•
Do not expose the meter to excessive vibration (greater than 0.5 g continuously).
Vibration levels in excess of 0.5 g can affect the meter accuracy.
•
For optimal performance of the meter, ensure that operating conditions correspond
to the meter calibration-type code and boundary.
•
Ensure that all piping connections conform to the local and national regulations and
codes of practice.
•
Follow fluid velocity guidelines and install the tines vertically for side insertion.
•
Properly tighten the transmitter housing cover after wiring to maintain ingress
protection and hazardous area approvals.
•
After installation, pressure test the meter and the associated pipework to 1
½
times
the maximum operating pressure.
•
Install thermal insulation in the meter, the inlet, and the bypass-loop pipeline to
maintain stable temperatures. The thermal insulation should cover the process
connection.

Power requirements
Following are the DC power requirements to operate the meter:
•
24 VDC, 0.65 W typical, 1.1 W maximum
•
Minimum recommended voltage: 21.6 VDC with 1000 ft of 24 AWG (300 m of
0.20 mm
2
) power-supply cable
•
At startup, power source must provide a minimum of 0.5 A of short-term current at
a minimum of 19.6 V at the power-input terminals.
