Some of the capabilities designed into the DANIEL INDUSTRIES MODEL 2500 MICROCOMPUTERS include: Minimal power requirements Network and remote communications Simultaneous orifice and turbine meter measurements Simultaneous gas and liquid measurement Both field and control room locations Multi-tube measurement and switching SECTION 2 5

18 AUG 1995 Model 2500 HARDWARE OPTIONS Design of the DANIEL INDUSTRIES MODEL 2500 MICROCOMPUTER hardware allows for two input/output (I/O) configurations, including a one-board configuration or a two-board configuration. The primary differences between the one-board unit and the two-board unit are the number of inputs and outputs each can handle. These two options provide for economy and flexibility when selecting an instrument for a specific installation. For example, an instrument originally installed as a one-board unit can be upgraded to a two-board unit at a later time if additional capacity is needed. The characteristics of the one-board and two-board configurations are outlined in the following table. Characteristic 1-Board Unit 2-Board Unit Remarks Analog Inputs 6 18 Rated at 4 to 20 ma or differential voltage 1 to 5 VDC Analog Outputs 2 4 Rated at 4 to 20 ma Status Inputs 6 24 Sense contact closure Control Outputs 6 24 Open collector outputs Optional solid-state relay with RTU terminal boards Prover detector switch input 1 2 Detects contact closure at the prover Pulse inputs 2 6 For pulse-generating primary sensing elements Frequency input 1 2 For frequency-generating primary sensing elements RS-232C serial communications port 1 2 Adaptable communications port* SECTION 2

SECTION 5 33

46 AUG 1995 Model 2500 INITIALIZING SEQUENCE When power is applied to the DANIEL INDUSTRIES MODEL 2500 MICROCOMPUTER during either a "cold" or "warm" startup, the computer automatically performs an initializing sequence. The sequence determines if the instrument is configured for a specific application and performs a series of self-diagnostic tests to ensure that all internal circuitry and devices are operational. When performing a "warm" startup after a power failure or a watchdog error, the front panel displays a copyright message and copyright date for several seconds before performing the initializing sequence. During a "cold" startup, the copyright message does not appear. NOTE: The DANIEL INDUSTRIES MODEL 2500 MICROCOMPUTER has a time-of-day clock chip in addition to the time maintained by the software clock in the operating system to provide time continuously during a power failure or when the unit is being stored. When the system is in operation, the clock chip is updated at two-hour intervals, shortly after midnight, and whenever the time of day is changed in the unit. 34 SECTION 5

50 AUG 1995 Model 2500 LIQUID METER PROVING Meter proving, a procedure utilized in determining the accuracy of a liquid meter, is normally applied to Positive Displacement and Turbine meters. In meter proving the indicated volume of fluid which passes through a meter is compared to the true volume measured in a pipeline prover of known size. By comparing the true volume to the indicated volume, a meter correction factor, which is expressed in the following formula, can be determined. Meter Correction Factor = True volume Indicated volume Provers are either uni-directional or bi-directional and measure non-interrupted liquid flow through Turbine or Positive Displacement meters. Inside the prover is a displacer, in the shape of a sphere or piston, which is forced through the prover by line pressure. As the displacer travels from one end of the prover to the other, it comes in contact with detectors mounted in the wall of the prover. The amount of displaced liquid between the two detectors is the true volume. Flow from the main line is diverted into the prover causing the displacer to begin moving from one end of the prover to the other. As the proving routine begins, pulses from the transmitter of the meter being proved are directed to a prover counter. The prover counter accumulates the meter pulses when the displacer actuates the first detector switch and then continues to accumulate pulses when the displacer actuates the second detector switch. The prover counter then ceases to accumulate pulses from the meter. At this point, the meter correction factor can be calculated by using the following formula. Meter Correction Factor = Volume displaced between switches Volume indicated by accumulated pulses 38 SECTION 5

51 AUG 1995 Model 2500 PROVING SEQUENCE The DANIEL INDUSTRIES MODEL 2500 MICROCOMPUTER with a single-board configuration (MODEL 2521 series) handles proving for one meter, while the dual-board configuration (MODEL 2522 series) handles proving for up to five meters. For further information, please refer to Drawing DE in the Appendix for a block diagram representation of the proving sequence. Automatic proving is setup to occur: At a pre-selected time every day (e.g. contract hour) Whenever operating conditions warrant meter proving, such as at changes in temperature, flow rate, density, etc. PROCEDURE SUMMARY For a combination of changing conditions and times The following steps describe the sequence of events that the DANIEL INDUSTRIES MODEL 2500 MICROCOMPUTER goes through in a proving sub-routine for a bi-directional prover. 1. The proof request is received by the unit. 2. The unit waits for the temperature in the meter to come within a certain number of degrees of the temperature of the prover. The length of time the unit waits for temperature stabilization and the proximity of the meter temperature to the prover temperature may be selected by the operator. 3. The unit sends a rotate command to the 4-way valve. If the 4-way valve does not rotate and report the proper status, such as "valve properly seated and sealed", the proof aborts. 4. When the 4-way valve is rotated, flow is diverted into the prover. 5. The displacer begins to move, which actuates the first detector, and the unit senses the first detector. 6. After the unit senses the first detector, it begins to accumulate pulses, meter temperature and pressure, and prover temperature and pressure. It also monitors SECTION 5 39

52 AUG 1995 Model 2500 the prover for seal integrity, and if seal integrity is lost during the proving run, the unit aborts the proof. 7. The unit continues to accumulate pulses, meter and prover data until the second detector is sensed. If the second detector is not sensed in the length of time defined by an operator entry, the proof aborts. 8. The unit makes another pass through the prover as previously outlined in Steps 3 through 7. For a bi-directional prover, one pass is considered half of a total run. 9. The unit will calculate a trial meter factor based on the total pulses, average temperatures, and average pressures of the total proving run. 10. The unit will run x number of operator-entry trial runs. The number of trial factors will be compared, and if each of the trial factors are within a certain percentage, which is entered by the operator, of each other a valid proof has been accomplished. 11. If a valid proof is completed, the final meter factor is calculated from the average of the data, which includes the pulses, temperatures, and pressures collected for the x trials. 12. If the comparison in Step 10 was not valid, another trial is run and the last x consecutive trials will be tested as in Step 10. The unit will run up to ten trials to achieve the tolerance selected by the operator and will print both the results of each of the trial runs as they are completed and the results of the final meter factor calculation. If the tolerance is not achieved after ten trials, the proof is aborted. The previous steps described for a proving sub-routine for a bi-directional prover are the same for a uni-directional prover, except that for a uni-directional prover: Unit sends a launch command to the prover interchange One pass constitutes a total proving run 40 SECTION 5

53 AUG 1995 Model 2500 PROVING CONFIGURATION When the DANIEL INDUSTRIES MODEL 2500 MICROCOMPUTER is utilized for meter proving, it is usually used in conjunction with the DANIEL INDUSTRIES PROVER RELAY ASSEMBLY (Daniel P/N ). The control outputs (open-collector) are used to select the meter to be proved. For further information, refer to Drawing CE in the Appendix. For the corresponding connections of Termination Board Daniel P/N to P/N or P/N to P/N , refer to Drawing ES or ES respectively. As an example of when a DANIEL INDUSTRIES MODEL 2500 MICROCOMPUTER is used in conjunction with a DANIEL INDUSTRIES PROVER RELAY ASSEMBLY, consider a metering system with five turbine meter runs where each meter must be proved through a bidirectional prover at the contract hour. The steps involved in accomplishing this for each meter are as follows: 1. A request for proof of meter number one is received by the DANIEL INDUSTRIES MODEL 2500 MICROCOMPUTER. 2. The DANIEL INDUSTRIES MODEL 2500 MICROCOMPUTER control output associated with meter number one, "PROVE MTR #1", energizes relay number one of the DANIEL INDUSTRIES PROVER RELAY ASSEMBLY. 3. With relay number one energized, the pulses from meter number one are diverted to pulse input Channel Number One. This channel is dedicated to be the pulse input for the meter to be proved. 4. The unit sends a rotate command to the 4-way valve. 5. Flow is diverted into the prover and the displacer begins to move. 6. When the senses that the first detector switch has been actuated, it begins accumulating the pulses from meter number one. 7. When the second switch has been actuated, the pulse accumulation stops, and a second pass is run. For a bi-directional prover, one pass is considered half of a total run. 8. The calculates a trial meter factor based upon the total pulses, average temperatures and average pressures of the total proving run. SECTION 5 41

54 AUG 1995 Model Typically five trials will be run, but the total number of trial runs is selected by the operator. The five trial factors will be compared and if each of the five trial factors is within a certain operator-selected percentage of each other, a valid proof has been completed. 10. If a valid proof has been completed, the final meter factor is calculated from the average of the data collected for the five trials. 11. If the comparison in Step 9 is not valid, another trial is run and the last five consecutive trials will be tested as in Step 9. The DANIEL INDUSTRIES MODEL 2500 MICROCOMPUTER will run up to ten trials to achieve the tolerance selected by the operator. If the tolerance is not achieved after ten trials, the proof is aborted. 42 SECTION 5

55 AUG 1995 Model 2500 BASE25 EPROM CHANGEOUT Before changing out any EPROMs, the operating parameters for the DANIEL INDUSTRIES MODEL 2500 MICROCOMPUTER must be recorded. This will help insure that setup remains the same after change takes place. NOTE: The Numeric and Selection Operator Entries will contain most of the special setup parameters. The following steps describe the sequence of events for changing the EPROMs in the DANIEL INDUSTRIES MODEL 2500 MICROCOMPUTER. 1. Discontinue power to the unit. 2. Locate the Base25 EPROM(s), which are installed in sockets U36 through U39 on the CPU I/O PC board as shown in the following table. Access to the board is obtained by unlatching the unit from the enclosure (see underneath the front panel) and sliding the unit out of the enclosure just far enough so that the left-hand board may be moved to the rear (see catch underneath and toward the rear). The EPROM(s) are on the right board (CPU I/O PC Board) located in the sockets, which are marked U36 and U Remove the old EPROM(s) as indicated in Figure Install the new EPROM(s) in the correct sockets, as specified in the following table. SOCKET U36 U37 U38 U39 DESIGNATOR E000 E800 F800 F000 SECTION 5 43

56 AUG 1995 Model 2500 Ensure that all pins of the EPROM(s) are installed correctly with the locator notch on the EPROM lining up with the socket notch, regardless of the orientation on the EPROM labels. 5. If the Model 2500 is a two-board unit (Model 2522), remove the old EPROM, if present, and install the Memory D800 EPROM into socket U44, as shown in Figure 5-2. Ensure that all pins of the EPROM(s) are installed correctly with the locator notch on the EPROM matching the socket notch, regardless of the label orientation on the EPROM(s). 6. To make sure the Random Access Memory (RAM) has no extraneous information, on the CPU I/O Board, briefly short pin 14 to pin 28 on U34 and U35. This is illustrated in Figure 5-1. If the DANIEL INDUSTRIES MODEL 2500 MICROCOMPUTER is a two-board unit, briefly short pin 14 to pin 28 on U24, U28, and U38 of the I/O Expansion Board as shown in Figure After installation is completed, close up the unit and apply power. The front panel LCD screen should display the following message: AWAITING CONFIG P2 B2400 ID Download the desired application program and setup the various operating parameters.
