Neptune TRU/FLO® compound meters are designed for extreme accuracy in highly volatile flow rate applications such as hospitals, apartment buildings, and hotels. Because the TRU-FLO-Compound-Meter uses a minimum number of parts, incorporates our maintenance-free valve, and comes standard with the patented throttle valve designed to protect the positive displacement meter from premature wear the TRU/FLO is considered the standard commercial water meter. It goes without saying that the Neptune TRU/FLO compound meters maximize revenue.

The performance of all TRU/FLO compound water meters meets or exceeds the latest accuracy requirements set by the AWWA C702 and allow maximum continuous flow rates to be exceeded by as much as 25% for irregular periods.

Sizes: 2” HP, 3”, 4”, 6” and 6” x 8”
