Fire Hydrant Meter - RPZ

RG3 Fire Hydrant Meter with RPZ is for use in measurement of potable cold water up to 140˚F and working pressures up to 160 psi. The meter will perform with accuracy registration of 100% + 1 1/2% within the typical operating range. Both pressure lossand accuracy tests are made before shipment, therefore no adjustments need be made before installation.  The meter is designed for use where water flows in one direction from a fire hydrant. It may also be used for temporary metering of irrigation, well pumping, construction, testing or similar non-permanent applications. Water flows into the meter’s measuring element driving a rotor where the revolutions are transferred to a register by magnetic drive coupling through the meter’s cover plate.  The meter shall be installed with the direction of flow as indicated by the arrow cast in the meter case. The meter may be installed in horizontal or inclined positions up to 45˚, with the register facing upward. It is recommended that a gate valve be located downstream to control flows.

 RG3 Fire Hydrant meters consist of several basic components: light weight aluminum main case, turbine type measuring element assembly, sealed register, aluminum cover plate, stainless steel hardware, brass lid assembly, aluminum or brass swivel and nipple, aluminum or stainless steel handles, etc. The measuring element assembly includes the rotor assembly, vertical shaft and a calibration vane.  Fire Hydrant meters come with an inlet strainer built into the swivel.
