Neptune maintains a Meter Support Department which handles questions concerning our meters and related products.  This includes residential,  commercial, and industrial meters, in addition to telemetry products like our TRICON^® family of electronic transmitters.  We're here to answer your questions. 

Residential Meters, 5/8" through 1"
Every T-10 water meter meets or exceeds the latest AWWA C700 Standard. Its nutating disc, positive displacement principle is time proven for accuracy and dependability since 1892, ensuring maximum utility revenue.  This type meter is almost always used to measure the water consumption in the residential market.

Commercial 1-1/2" and 2" Intermediate Meters
These T-10 water meters also meet or exceed the latest AWWA Standard. They also contain the nutating disc, positive displacement principle for capturing low  flow rates.  
Application - These meters might be used at convenience stores and other small-to- medium commercial applications where the flow rate is not expected to exceed 160 gallons per minute.

Commercial High Performance (HP) Turbine Meters
HP Turbine water meters offer some of the widest flow ranges of any turbine meters on the market. All HP Turbine water meters meet or exceed the latest performance and accuracy requirements of AWWA C701. 
Application - The HP Turbine water meter is designed for applications where flow rates are consistently moderate to high, such as processing plants, manufacturing facilities, effluent water in treatment plants, inter-system sales or custody transfer, and office buildings.

Commercial Compound Meters
All TRU/FLO^® Compound water meters meet or exceed the latest performance and accuracy requirements set by the AWWA C702.
Application - The TRU/FLO Compound water meter is designed to register wide-flow ranges where varying flow rates are typical. TRU/FLO meters combine the low-flow sensitivity of a disc-type meter with the high-flow capacity of a turbine-type meter, and are used in areas such as apartment buildings, motels, hotels, condominiums, mobile home parks, schools, restaurants, dormitories, department stores, and shopping malls.

Industrial Fire Service Meters
