Neptune® Fire Hydrant Meter

We Currently Only Sell In Alberta and NWT

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.

Fire Hydrant water meters are designed for mobile use in metering flows from fire hydrants.


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.
