*Optional installation hardware may be provided in place of this fitting

Please notify ONICON if any of these items are missing.


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 email 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.


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.

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.
