The Neptune High Performance (HP) Turbine is designed for applications where the flow is consistently moderate to high.
 

Each Neptune HP Turbine water meter consists of a rugged bronze maincase, an AWWA Class II turbine measuring element, and a roll-sealed register.

The bronze maincase is corrosion resistant, lightweight and compact. Inlet and outlet connections are flanged. Neptune strainers are available to prevent debris from entering the meter, and to reduce the effects of uneven water flow due to upstream piping variations.

The Unitized Measuring Element (UME) allows for quick, easy, in-line interchangeability. Water volume is measured accurately at all flows by a specially designed assembly. Self-lubricating bearings provide equalized rotor loading for accuracy over a broad flow range. The thrust compensated rotor configuration relieves pressure on the thrust bearings which minimizes wear and provides sustained accuracy over an extended operating life. Direct coupling of the rotor to the gear train eliminates revenue loss due to slippage during fast starts and line surges. A calibration vane allows in-field calibration of the UME to lengthen service life and to ensure accurate registration.

Neptune HP Turbine water meters offer the widest flow range of any turbine meters on the market. All Neptune HP Turbine water meters meet or exceed the latest performance and accuracy requirements of AWWA C701 and maximum continuous flow rates may be exceeded by as much as 25% for intermittent periods.
