5 Flo-Tote Communications 6 I n Addition to many reporting and data management functions, the Flo-Tote File Driver allows for communications and other instrument services for your Flo-Tote system. These features allow you to perform: Site Setup: Used to configure your flowmeter to a particular metering site. Read Meter: Used to transfer stored data from your flowmeter to your computer system for data processing. Real Time: Used to view instantaneous data from the connected flowmeter. View Data: Used to view stored data files on your computer system. Preferences: Used to select the default file path where your data files will be saved to. Flo-Tote Communications 48

6 Site Setup S ite Setup is used to configure your flowmeter to a particular metering site. Once a setup has been sent to the flowmeter, then it will stay at that configuration until a new setup is sent to the meter. Sometimes you may find it convenient to pre-setup metering sites in the office as opposed to performing the setup in the field. In this case, you can save setups by clicking the Save Site button. Once in the field, you may simply choose the particular site where you are located and choose the Send Setup button. Clicking the Delete Site button will remove the active site from your computer system. Note: Saving a setup does not affect the setup in the meter. Changes take effect only when a setup is sent to the meter. In addition, sending the setup to the meter will automatically save the setup on your computer system. Therefore, if you send a setup to the meter, it is not necessary that you take the extra step of saving the setup by clicking the Save Site button. Caution: Sending a setup to the connected flowmeter will clear any data that resides in the flowmeter memory. Flo-Ware TM will warn you of this prior to executing the Send Setup command. If there is valuable data in the flowmeter that you have not previously read, choose Read Meter. See Reading a Meter in this handbook for detailed instructions. Note: During the Send Setup procedure, Flo-Ware TM will pop up a dialog box displaying the date and time stored in your flowmeter s clock and your computer s clock. If necessary, it is at this point you may edit the date & time of the flowmeter clock. 7 In This Section Editing Site Setup Data Level Calibration Level Offset Calculation Site Coefficient Calculation.9 Vmax Method.4 Method.8 Method.2,.4,.8 Method Known Average Method Channel Setup Auxiliary Channels Site Setup 49

7 Editing Site Setup Data The site setup entries should all be carefully checked before sending the setup to the flowmeter. Setups that have been previously sent to a meter or previously saved can be retrieved by clicking the Site ID drop down box. Once the box drops down you can scroll through the available setups. Once the desired site is highlighted, leftclick your mouse to select it. Left-clicking the Read Setup button will initiate communications with the connected flowmeter and the setup data will be transferred from the flowmeter to the screen of your computer. Once the setup is displayed, you can choose Save Site to save the setup from the connected flowmeter. Site Setup Fields Site ID drop-down box: Enter an Alpha-numeric descriptor (i.e., Manhole Number) to identify the site being setup. Location edit boxes: Enter information that describes the location of the site being setup. Flow Units drop-down box: Choose the flow units that you would like to use from the drop-down box. Sample Time edit box: Choose the length of time, in seconds, that you would like the flowmeter to sample for each cycle that it logs. Cycle Length edit box: Choose the interval (how often) that you would like the flowmeter to turn on and sample data. Start Type drop-down box: Choose Immediate to commence sampling once the setup has been sent to the flowmeter, Delayed to start the sampling at a pre-determined date and time, or External to trigger the flowmeter to start from an external device. Memory drop-down box: Choosing fixed will instruct the flowmeter to shut down after the memory is full. Choosing Wraparound will instruct the flowmeter to overwrite data in memory once it is full. Shape drop-down box: Choose the shape of your monitoring channel (i.e., circular, rectangular, odd, or full pipe) Size edit box: Enter the dimensions of your monitoring channel. If the shape is odd, select a table number that you have previously created with the Marsh-McBirney Shape Generator program. Several items may require extended information to setup your flowmeter properly. To access these features, left-click the Calc Button next to the corresponding item. These items are as follows: Level Cal. - Adjusts the calibration in the level measurement system. Level Offset - Compensates for situations where you may need to rotate the flowmeter sensor to a position in the pipe other than the bottom (6 o clock position). This is often used when there is significant silt at the bottom of the monitoring channel. Site Coeff. - Used to obtain optimum accuracy from the flowmeter. The Site Coefficient mathematically converts the local velocity from the flowmeter sensor to an accurate average or mean velocity through the entire flow stream. Channels - Single-tap to launch the instrument channels setup screen. Channel setup allows you to turn the standard level and velocity channels on/off, and configure the auxiliary channels (voltage inputs, pulse input, & contact closure outputs). Note: Descriptions on how to setup these extended information fields is detailed on several following pages of this handbook. Communications: Choose either direct (cable) or modem for the communication type. Editing Site Setup Data 50

8 Level Calibration Each time, prior to installation, it is recommended that you perform a level calibration on the instrument to be installed. The level calibration feature allows you to adjust the calibration in the level measurement system. Calibrating the level will help you obtain maximum accuracy from the flowmeter. The range of error that can be adjusted is +2 to -4. If readings are beyond this range or are very erratic, contact the Marsh- McBirney Customer Support Group. Note: When calculating a Level Cal it is recommended that you use a bucket of water to obtain the value. A bucket of water is a much more controlled environment than that of the dynamic flow conditions in a sewer pipe. If you do use a bucket of water, then you should choose Pipe Bottom in the Meas. From drop-down box To Calculate a Level Calibration 1 Left-click the Calc button next to the Level Cal. edit box 2 Enter whether the true depth reading is from the top of the pipe (air gap) or the bottom of the pipe in the Meas. From drop-down box. 3 Depending on your entry in the Meas. From drop-down box, enter either the air gap or actual depth (obtained by a ruler or tape measure) under the Meas. Level edit box. 4 Launch Real Time by left-clicking the Start button. After viewing the level for several readings, stop Real Time by left-clicking the Stop button. Enter the sensed level (real time reading) into the Sensed Level edit box. Once you have entered this value, Flo-Ware TM will automatically calculate the Level Cal for you. 5 Left-click the OK button to go back to the Setup screen. The new value will be in the Level Cal. edit box. Note: If you already know a value or are dissatisfied with the Level Cal results, you are free to type a value in the Level Cal. edit box.

9 Level Offset To Calculate a Level Offset Left-click the Calc button to launch the Level Offset window. The Level Offset should not be, but is often confused with the level calibration. The level calibration is an adjustment for the level calibration in the sensor and should be performed before the level offset calculation. The level offset is an adjustment for the radial location of the sensor in the monitoring channel. For instance, if your monitoring channel has sediment in the bottom of it, you may have the need to rotate the sensor at a different position than the bottom of the pipe (above the sediment level). To compensate for this change, you must adjust the level offset. By default, the level offset is set to.4. This is the distance between the bottom of the sensor and the port where level is measured on the sensor. If the sensor of the flowmeter is placed at the bottom of the monitoring channel, the level offset should be set 1 Left-click the Calc button next to the Level Offset edit box. 2 Enter whether the true depth reading is from the top of the pipe (air gap) or the bottom of the pipe in the Meas. From drop-down box. 3 Depending on your entry in the Meas. From drop-down box, enter either the air gap or actual depth (obtained by a ruler or tape measure) under the Meas. Level edit box. 4 Launch Real Time by left-clicking the Start button. After viewing the level for several readings, stop Real Time by left-clicking the Stop button. Enter the sensed level (real time reading) into the Sensed Level edit box. Once you have entered this value, Flo-Ware TM will automatically calculate the Level Offset for you. 5 Left-click the OK button to go back to the Setup screen. The new value will be in the Level Offset edit box. Note: If you already know a v alue or are dissatisfied with the Level Offset results, you are free to type a value in the Level Offset edit box. Level Offset: Start Real Time Stop Real Time Instantaneous Values Averaged Values Number of readings to average. Real Time must be stopped before changing. Level Offset 52

10 Site Coefficient Calculation The site coefficient is a value that is used to convert the sensed velocity to an average velocity so that an accurate flow measurement can be obtained. A default value of is used by Flo- Ware TM. However, to optimize the accuracy of the flowmeter, a site specific site calibration coefficient should be used. There are several ways to obtain this value. Although there is no one right way, it is always a good practice to try and utilize at least two different methods when obtaining a site coefficient. This will help minimize any error in the measurement system. Choosing a Calculation Method. To choose between methods: 1 Left-click the Calc button next to the Site Coeff. edit box. 2 Left-click the arrow on the Cal. Method drop-down box. 3 Choose the method you would like to use. Note: Once you choose a method and depending on what method you choose, you will see that additional controls may become visible. This is the information required for that particular method to properly calculate a site coefficient for you. Calibration Method Left-click the Calc button to launch the Site Coeff. window.

Available channels to Trigger From: None Note: Net totals, + Total, and - Totals are calculated at the end of each sample and compared to the Trigger Value. If the Trigger value has not been reached, the value is added to the next sample taken. This is repeated until the trigger value is reached. If the total ends up being greater than the trigger value, the contact will close and the difference between the Trigger Value and the flow total will be added to the next sample taken. Auxiliary Channels 60

18 Full Pipe Setup Flo-Ware for Windows provides support for the Model 268 full pipe flowmeters. These meters utilize a velocity only sensor and an optional pressure sensor. Flow is calculated by multiplying the mean velocity by the area of the full pipe. The pressure option is used to record the pressure in the pipe being monitored. Pressure is not used for the flow calculation. Note: To obtain optimum accuracy from the flowmeter, profiling techniques should be used. Instructions on how to profile flow in a closed pipe can be obtained by Marsh-McBirney, Inc. This manual discusses the software setup of these instruments. Profiling techniques are out of the scope of this manual. Titles: Full Pipe One Inch Sensor : Installation and Field Calibration Manual Two Inch Full Pipe Sensor : Installation and Profiling Manual To setup the flowmeter for full pipe: 1. Choose Full Pipe from the Shape drop-down box. Note: Several controls will change to items related to the full pipe setup. These items include; Pressure Zero Cal, & K1 setup Pressure Sensor: Pressure Cal: This edit box allows you to adjust the zero calibration of the pressure sensor. It is recommended you calibrate the sensor to atmospheric pressure (in air). In this case, the reference pressure is zero. The difference between zero and the pressure sensor reading is the pressure calibration value used. To calculate the pressure zero: 1. Click the Calc button next to the pressure cal edit box. 2. Enter the reference pressure in the Ref. Pressure edit box. Note: It is recommended you calibrate the sensor to atmospheric pressure (in air). In this case, the reference pressure is zero. 3.

After several consistent and stable readings are acquired choose Stop. 4. Enter the Sensed Pressure in the Sensed Pressure edit box. Pick a value that is the average of the consistent readings you see. 5. The Pressure Zero will calculate. Choose OK and the value will automatically be placed in the Pressure Zero edit box of Site Setup. Full Pipe Full Pipe Setup 61

19 Full Pipe Setup Cont. The K1 value modifies the sensed velocity ( velocity around the sensor) to an accurate mean velocity through the flow stream. The K1 is calculated by knowing; 1. The sensed velocity of the flow stream 2. The mean velocity of the flow stream The sensed velocity is what the sensor calculates in its operating position within the pipe. The mean velocity is the average velocity throughout the crosssection of the flow stream. To obtain optimum accuracy from the flowmeter, profiling techniques should be used. Note: Instructions on how to profile flow in a closed pipe can be obtained by Marsh-McBirney, Inc. This manual discusses the sof t- ware setup of these instruments.

24 Site Information 12 Once a Flo-Tote data file has been loaded into a project, Site Information can be accessed by right-clicking any of themes that represent data from the file loaded (i.e., flow, level, velocity). Choose Site Information to launch the Site Information dialog box. Accessing this feature allows you to both view and modify any available information. A specific feature that adds power and flexibility to the Flo-Tote File Driver is the ability to utilize many site coefficients in your Flo-Ware TM project. The site coefficient is a value that is used to convert the sensed velocity to an average velocity so that an accurate flow measurement can be obtained. While, in most cases, a single site coefficient value will yield ample accuracy, you may find the need to use several. This may be due to; surcharge conditions, pipe bends, turbulence, etc. Whatever the reason, Flo-Ware TM and the Flo-Tote File Driver provide a multiple site coefficient facility for you. Checking the Display Site Cal as Theme option, will enable this feature. Choose OK to invoke changes and the site calibration coefficient will be displayed as a theme in your raw data. Using the Find / Replace feature will then allow you to customize the Site Coefficient based on level for instance (i.e., find all levels less than 3 inches and replace Site Coeff. with Find all levels greater than 3 and replace Site Coeff. with , and so on). As you can see, virtually any amount of site coefficients are available to you. Of course when you change the site coefficient, flow will dynamically recalculate based on the changes you have made.
