SYSTEM-40 BTU MEASUREMENT SYSTEM
SECTION 3.0
INSTALLATION
The System-40 BTU Meter should be installed by experienced contractors
with related knowledge and experience in hydronic heating and cooling
systems, and fluid metering applications in general. Contact ONICON for
installation assistance.
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, tube cuttings or any other free moving debris.
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.
When selecting a site for mounting the system components, consider the
criteria under Section 1.6: WORKING ENVIRONMENT, as well as the following
limitations that 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 fixed 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, the temperature sensor adapter bushings
and the thermowells is 400 psi.
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.
