FM Fire Pump Test Flow Meter
Flowmeter for fire pump is mainly used to measure the volume flow of conductive liquid and slurry in closed pipes. Including acid, alkali, salt and other highly corrosive liquids.
Fire pump flowmeters may be used to determine the discharge of a fire pump. Water from the pump is temporarily directed through
the flowmeter, then to atmospheric drain or back to the water supply source.
It is important that the flowmeter not be connected directly back to the pump suction. This arrangement does not adequately test the
condition of the water supply.
These flowmeters are calibrated to measure the fire pump output directly in gal/min (dm3 /min). A control valve is provided in the
flowmeter line. This valve must be completely closed, except when the flowmeter is in use. Unless otherwise noted in the listing, these
systems have 175 psi (1205 kPa) rated working pressure.
