Integral Brodie Electronic Rate Totalizer
(BERT-E)
If the instrument has been supplied with an inte-
gral electronic register, the internal wiring connec-
tions will already be in place. For additional func-
tions and wiring possibilities please refer to the
BERT-E’s instruction manual.
8.3 - Meter Start Up and 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 al-
low 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 over-
speed 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 pres-
surize 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 in-
strument to run at 20% of its rated fl ow for 5
minutes.
3. During this initial run, check all other compo-
nents 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 ex-
ceeded.
