Neptune’s Fire Hydrant water meter is designed for mobile use in
metering flows from fire hydrants. The meter measures a wide flow range to maximize revenue. It meets or exceeds
the latest performance requirements of AWWA. Maximum flow rates may be exceeded by 25% for intermittent flows.
The
Fire Hydrant water meter consists of a lightweight, aluminum maincase fitted with a 2” gate valve, a turbine
measuring element, and a roll-sealed register.
The aluminum maincase is Xylan® coated for corrosion resistance and is lightweight, compact, and easy to
handle. This meter features a unique “balanced handle” which makes carrying and installing it easier than any
other fire hydrant meter on the market. A 2” gate valve enables the user to regulate the water f low without
opening and closing the fire hydrant.
The unitized measuring element (UME) allows for quick and easy
interchangeability. Exclusive dual graphite bearings provide equalized rotor loading for accuracy over a broad
f low range.
The thrust-compensated rotor configuration relieves pressure on the thrust bearings, which
minimizes wear and provides sustained accuracy over an extended operating life. A tamper-resistant stainless
steel calibration vane allows re-calibration of the UME to lengthen service life and to ensure accurate
registration. The roll-sealed register eliminates leaking and fogging. A magnetic drive couples the register
with the measuring element.
