The instrument should not be located in a location
where excessive vibration is to be expected.
Care should be taken not to locate the instrument
near any source of electromagnetic interference, such
as those produced by electric motors, transformers,
solenoids, etc.
Either of these factors could induce a signal into the
fl ow sensing pickoff and interfere with the accuracy of
line product measurement.
9.1 Operation
Review the system installation to ensure all the
components are in proper sequence, all isolation
valves must be closed, all electrical connections are
complete, and all covers are in place.
1. To pressurize the system, slowly open the inlet
valve so as to prevent system shock. Slowly allow
product to enter the system whilst keeping the
downstream isolation valve closed.
2. Open the downstream valve (10%) to allow any air
to be fl ushed from the system. Do not overspeed
the instrument.
3. Once the air has been fl ushed from the system,
close the downstream isolation valve and check
for any leaks. If leaks are found, check all seals
and retighten connections.
4. Fully open the upstream isolation valve to
pressurize the system.
Flow start up can commence once the sytem has been
pressurized.
1. Turn on all electronic circuits and check for proper
function.
2. Open
fl ow control valves and allow the instrument
to run at 20% of its rated fl ow for 5 minutes.
3. During this initial run, check all other components
in the system for functionality.
4. Once this run is complete, set the fl ow control
valve to the required fl ow and ensure that the
maximum fl ow for the instrument is not exceeded.
