7. OPERATION
7.1 Flushing the Piping Assembly
A newly installed piping assembly where scale,
sludge and other foreign matter are expected requires
flushing the piping assembly before commencing
meter operation.
In order to safeguard the meter, use a bypass line for
flushing. If there is no bypass line, install a short pipe
section in place of the meter as shown in Fig. 7.1.

7.2 Operation Procedure
(1) Drainage (in steam service):
To prevent steam hammer, drain the piping assembly completely.
(2) Checking the meter for proper installation:
To ensure safety, inspect connecting bolts, gaskets, and other members for tightness and other conditions.
Make sure of the flow direction also.
(3) Leak check:
Fill the meter with the fluid and check for any leak.
(4) Turning power ON:
Upon completion of wiring connections, turn on power.
Verify that the receiving instrument does not register erratic counts with no flow.
(5) Starting up the measurement line:
By starting up the pump or opening the valve, carefully allow the fluid to flow.
CAUTION: To safeguard the equipment connected, avoid a sharp increase in
flowrate.
(6) Operation check:
Verify that the receiving instrument registers the flow correctly.
Make sure that the fluid conditions (pressure, temperature, etc.) and flowrate conform to the meter
specifications.
