Neptune/Actaris Type S Flowmeters
Sizes 1-1/2" and 2"

The 1-1/2" & 2" Type S flowmeters utilize the nutating disc principle positive displacement measuring chamber technology. This design results in an extremely accurate meter which is insensitive to small changes in viscosity and flow profile disturbances. Each meter includes the base meter unit which houses and protects the measuring chamber and the gear train, with available units of measure of liters, kilograms US gallons and pounds. Registers provide reset of delivery and totalization and a wide variety of digital pulse and analog transmitters permit remote operation and monitoring.

The Neptune design nutating disc measuring chamber is both accurate (100% + or - 1.0%) and dependable, with repeatability of 100% + of - 0.1%. For specific flow ranges, with reduced variables, accuracy's of 100" + 0.5% are easily obtained. The double case construction reduces the effect of higher pressure losses in measuring viscous liquids. In addition, the disc design can accurately measure liquids with solid particles (up to .22mm/.009") without major damage or erosion to the measuring element for intermittent operations.

The rugged bronze outer body components are compatible with hundreds of nonacidic liquids. Flanged end connections allow rapid conversion from right to left hand flow. Pulse transmitters, coupled with the BATCHMATE (electronic batch control) and a locally acquired solenoid valve, result in an economical and dependable local or remote batching system.

Rugged construction assures a simple and economical system proven through more than 100 years of manufacturing experience. The nutating disc design offers low pressure differential and double case construction, resulting in an exceptional ability to measure a wide variety of mild corrosive and erosive liquids.

The Type S flowmeters do not require elaborate timing gears or difficult adjustment procedures to insure proper function of the measuring element. Replacement of a worn or damaged measuring chamber, gear train or register is a quick and easy process.

Time proven positive adjustment by means of patented Neptune calibration (change) gears allows changes in increments as small as 0.15% and reduces errors caused by vibration and tampering.
