When placing your meter in operation, the meter and system must be
lled slowly with liquid and be free of air prior to start-up. Extreme care
must be taken to avoid damaging the meter during this time. When lling
the system with liquid for the rst time, gravity lling is the preferred
method of lling the system with liquid. Gravity lling uses positive head
pressure from product storage above the inlet port of the meter to ll the system. If necessary, systems can be lled
with the pump.

1. Make sure all valves (upstream and downstream of the meter) in the system
are closed.
2. Open the valve located at the storage tank a small amount. Provided there is
not a valve between the tank and the meter inlet, the meter’s register/counter
will start to move and then stop. If there is another valve between the tank and meter, repeat this process with each valve until
the meter is exposed to the liquid.
3. Once you are assured that the meter has registered some volume and stopped, continue to open the tank valve until it is
completely open.
4. With the valve(s) open between the tank and the meter, slowly open the downstream valve until the meter’s register/counter
starts to move. Do not run the meter any faster than 25% of its rated ow during start-up. Once the product is owing out of the
end of your system, the outlet valve can be opened all the way, provided that the system is designed not to exceed the ow
rate marked on the meter.

Make sure that your pump can operate
against a dead head pressure. If not,
consult the factory for assistance.
Dead Head Pressure - Pumps
Prime the pump before using it to ll the
system. Consult the pump manufacturer
for proper pump priming.
Prime the Pump First
Before disassembly of any meter or accessory component:

If these conditions cannot be avoided, air and vapor elimination
systems may be required. If you cannot ll the meter slowly by
gravity or by using a valve to throttle back the ow, consult the
factory.

If the ow remains constant and varies within narrow limits or if
the product is viscous, the meter can be calibrated for ows below
minimum ratings. If the meter is installed in a custody transfer
application (for nancial transactions), the ow rate must fall within
ow rate range indicated on the serial number plate. A meter
should never be run beyond the maximum ow rate determined for
that class meter and/or liquid measured.
