System-40-BAC BTU Meter Manual 03/ Page 7

8 SECTION 3.0: INSTALLATION The SYSTEM-40 BTU Meter should be installed by experienced plumbers, electricians, and others with related knowledge and experience in the heating, cooling, and fluid metering fields. ONICON technical support personnel are available via telephone or to provide technical assistance before, during and after installation. On-site field engineering, installation, and service are also available at an additional cost. The installer should use good trade practices and must adhere to all state and local building, or other, applicable codes. Before you begin, clean the external surfaces of all pipes at the installation sites so that they are free of debris, foreign matter, solids, leak inhibitors, and chemically aggressive substances. Flush the entire system so that it is free of flux, solder, pipe and tube cuttings and any other free moving debris. 3.1 SITE SELECTION Careful attention to the site selection for the system components will help the installers with the initial installation, reduce start-up problems, and make future maintenance easier. For example, do not install the flow sensor where it will be difficult for personnel to perform periodic maintenance. When selecting a site for mounting the system components, consider the criteria under Section 1.5: WORKING ENVIRONMENT, as well as the following. The following limitations apply to the installation of the meter: The flow sensor body must be correctly oriented with respect to the direction of flow in the pipe. Meters installed with reversed flow will not function. The System-40 is provided with 4.9ft (1.5m) cable lengths for the flow sensor and temperature sensors. Do not alter the cable lengths. Doing so will void the calibration and may invalidate the warranty. The maximum operating pressure for the flow sensor body, the direct insertion temperature sensors and the temperature sensor adapter bushings is 400psi. Ball valves provided for use with direct insertion temperature sensors have a maximum pressure rating of 232psi. Thermowells provided with the System-40 have a maximum pressure rating of 400psi. At fluid temperatures above 212 F the calculator enclosure should be remote mounted. Do not install the meter in close proximity to strong sources of electromagnetic interference (e.g. electric motors, VFD s, etc.) i IMPORTANT NOTE Proper site selection is critical to the performance of this Btu meter. Both the flow sensor and the remote temperature sensor must be properly located within the piping system in order to ensure an accurate energy measurement. System-40-BAC BTU Meter Manual 03/ Page 8

9 3.2 INSTALLING THE FLOW SENSOR When properly installed, the flow sensor will only measure flow associated with that portion of the piping system for which the energy measurement is being made. The flow sensor may be installed in either the supply or return pipe of the heat exchange circuit. Before you install the meter, the entire piping system should be flushed and free of debris. Please refer to the diagrams below when selecting the installation location. While many installation locations require little, if any, straight unobstructed pipe upstream or downstream of the sensor location, it is always recommended that the sensor be located with as much straight pipe upstream of the sensor as possible. C B D A Flow Direction G E & F Flow Direction A. This is a recommended position for the flow sensor. B. This is a recommended position for the flow sensor. C. Avoid installation locations where air can become trapped in the piping system. D. This is an acceptable installation location for closed loop pressurized systems. E. Do not install the sensor downstream of modulating valves or partially open valves. Fully open isolation valves (e.g. ball valves) are OK. F. Do not install the flow sensor at the inlet of a pump or anywhere else where the operating pressure in the pipe may drop below ambient pressure levels. To prevent cavitation, the minimum recommended operating pressure at the installation location should be at least 5psig. G. Avoid installing the meter downstream of multiple bends out of plane with each other where there are less than 10 diameters of straight unobstructed pipe between bends. System-40-BAC BTU Meter Manual 03/ Page 9

10 The flow sensor is installed with threaded meter couplings and flat sealing gaskets as shown below. Orient the sensor body by aligning the flow direction arrow with the direction of flow in the pipe. Retaining Nut Coupling Seal i Flow Direction IMPORTANT NOTE The sensor port is always on the downstream end of meter. The flow sensor body must be correctly oriented with respect to the direction of flow in the pipe. Meters installed with flow in the reverse direction will not function. The calculator enclosure may be rotated around the axis of the flow sensor into three different positions. To rotate, temporarily slide the enclosure off the flow sensor mounting brackets. Remove the two retaining screws and reposition the mounting brackets as required. Reinstall the enclosure with the display properly oriented for viewing. Mounting tracks on the back of the enclosure allow for mounting in any orientation. Slide calculator enclosure to remove from sensor mounting brackets Slide Enclosure Mounting Tracks Retaining Screw Retaining Screw i IMPORTANT NOTE When installing the meter in a vertical pipe with upward flow you must rotate the enclosure back plate 180 when rotating the display 90. To accomplish this, temporarily remove the 4 cover screws and rotate the backing plate. System-40-BAC BTU Meter Manual 03/ Page 10

12 3.3 INSTALLING THE TEMPERATURE SENSORS When properly installed, the temperature sensors will only measure the inlet and outlet temperatures of the heat exchange circuit where the energy measurement is being made. Before you install the sensors, the entire piping system should be flushed and free of debris Direct Insertion Temperature Sensors System-40 BTU meters configured with direct insertion temperature sensors are provided with one sensor pre-installed in the flow sensor body. The second sensor must be installed in the pipe opposite that of the flow sensor as shown below. The tapered sensors are provided with an M10 threaded fitting and a flat sealing gasket. For standard installations, an M10 x NPT bushing is provided for use with a customer supplied line size tee. The torque required to properly install the temperature sensors is 4lb-ft.! CAUTION The platinum RTD sensors provided with the System-40 are calibrated with the attached cables. Altering these cable lengths will result in significant measurement errors and void the meter calibration.

ONICON s sole liability and Buyer s sole remedy for any breach of the foregoing warranty is for ONICON to repair or replace, at ONICON s option, any defective product that is returned to ONICON during the warranty period. EXCEPT AS MAY BE SPECIFICALLY AGREED BY ONICON IN WRITING IN RELATION TO EACH SALE, NO OTHER WARRANTIES SHALL APPLY, WHETHER EXPRESSED, IMPLIED OR STATUTORY, AND THERE SHALL BE NO IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. 4. REMEDIES: ONICON s OBLIGATION UNDER THE FOREGOING WARRANTIES IS LIMITED SOLELY TO REPAIR OR REPLACEMENT, AT ONICON s OPTION, OF DEFECTIVE OR NONCONFORMING PRODUCTS. ONICON SHALL NOT BE LIABLE FOR CONSEQUENTIAL, INDIRECT, PUNITIVE, INCIDENTAL, OR SPECIAL DAMAGES WHETHER FOUND ON CONTRACT, TORT OR ANY OTHER THEORY OF LAW.

PATENTS: ONICON shall defend all suits or proceedings brought against Buyer or its customers arising from claimed infringements of any patent, trademark, service mark or copyright for any product furnished by ONICON and shall indemnify it against all costs, fees, and damages on the condition Buyer promptly notifies ONICON in writing and provides information and assistance to enable ONICON to conduct the defense, provided that ONICON shall have no such obligation in case of infringement resulting from ONICON s conformance to special requirements of Buyer.
