APPLICATIONS

Recommended for measuring high-volume water usage from fire hydrants or other fire protection systems. Convenient hose connections and light-weight construction make this portable turbine meter useful for accurately measuring water used to fill street sweepers, water tankers or other equipment.

 

CONFORMANCE TO STANDARDS

Hersey Model HM Water Meters comply with ANSI/AWWA Standard C701 class II. Each meter is tested to ensure compliance.

CONSTRUCTION
Hersey Model HM Water Meters consist of three basic parts:

D-I-M-E (Drop-In-Measuring-Element), bottom case and register. The D-I-M-E assembly contains all of the working parts inside of the meter and is easily removed from the bottom case when servicing is desired. The bottom case is constructed from cast aluminum to be lightweight and has built in carry handles for portability. The register is enclosed in a bronze register box. The rotor assembly is thermoplastic which is dimensionally stable and will not corrode. The inlet connection has a 2-1/2" female national hose thread swivel adapter and the outlet connection is 2-1/2" male national hose threads.
REGISTER
The permanently sealed register incorporates a bayonet style locking mechanism with Hersey's unique integral tamper pin. The totalizing register has a straight-reading odometer type display, a 360° test circle with center sweep hand and a low flow (leak) indicator.
OPERATION
Water flows straight through the turbine section where it turns a rotor at a rate in direct proportion to the amount of water flowing through the meter. The straight-through design allows high volumes to flow with a minimum of head loss.

Retro ThrustT rotor design extends the life of the meter by dividing wear between two points: during low flow the tungsten carbide thrust bearing floats against a sapphire bearing surface; during high flow the stainless steel shaft gently contacts a second sapphire bearing. During medium flow, the rotor floats between the thrust bearings without contact.
MAINTENANCE
The Hersey Model HM Meters are designed and manufactured to provide long service life with virtually no maintenance required. D-I-M-Es are available for field replacement and offer new meter accuracy and warranty benefits without field testing. Existing D-I-M-Es can be returned to the factory for refurbishment with new registers and measuring elements for installation later.
CONNECTIONS
Available with National Standard for fire hose coupling thread, female and male couplings.
