Start up Recommendations
Test equipment should be grounded to prevent a possible spark. Test area should have no ignition source. Operators should
wear personal protection and prevent any product exposure and environmental issues.
Start-up instruction for new installations or after maintenance and repairs:
1) Only properly trained personal should design, install, or operate metering system.
2) Remove plastic threaded plugs placed in meter for shipping protection. They are not to be used in
meter system because of the PVC plugs low rated pressure, compatibility, and sealing issues.
3) Place the meter in an area with ample workspace, secure from vibration, and pipe line stress. Mount
and bolt down on to a fixed stand or platform. This prevents meter stress, which will cause leakage
and metal fatigue.
4) Apply thread sealing compound and gasket materials that are compatible with product.
5) Do not weld to meter or meter accessories such as valves and air eliminators. This will weaken
housings, cause O-ring and casting leaks and potentially distort the critical tolerances within the flow
meter.
6) Always wear personal safety protection equipment such as goggles, steel toed shoes, gloves and full
body clothing.
7) Be sure to install a pressure relief valve or expansion joint in the system to protect against thermal
expansion.
8) Make sure all system components are properly secured and tightened.
9) All meter assembly bolts and connections are tight.
10) The air eliminator vapor release must be properly vented to atmospheric pressure and piped into a
reservoir container or back to the supply tank.
11) Electrical connections are properly installed and start/stop switches are off and locked-out.
12) Ensure that there is flooded suction to the Pump and that fluid is available to system to prevent the
starving or cavitation of the pump.
13) Flood the system slowly. Start the system with all shut off valves in the closed position. When a
pump is turned on and a valve opened in a new, dry system, tremendous liquid and air pressure can
build up in the piping and be forced through the meter. The high pressure and volume of air causes
the meter to rotate more rapidly than normal. When the fluid product reaches the meter, there is an
abrupt slowing of the meter rotor. This can cause damage to the register, rotor shafts, packing gear
and/or blade, timing gears and other components.
The recommended method of starting any system is to flood the piping gradually. This allows
product to slowly force the air from the entire system.
