3 FLOWMASTER OPERATION
The pressure gauge does not need a power source to
operate. Pressure measurements can be made with the
flow meter in the OFF position.
The Flowmaster is ready to measure flow as soon
as battery power is applied. Turn on the Flowmaster
by pressing ON/OFF switch to “1” position. The
Flowmaster can also be powered using an external 12V
DC power source.
Following power_on, the flow meter begins a self test
sequence lasting approximately 5 seconds and then
automatically enters flow measurement mode. The
typical flow meter display in flow measurement mode
is as shown below.
