Neptune/Actaris Type S Flowmeters
Sizes 1", 3/4" and 5/8"

The 5/8", 3/4" and 1" Type S flowmeters, with double case construction, 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 to small changes in viscosity and flow profile disturbances. Each meter includes a base unit which houses and protects the measuring chamber and the gear train. Registers provide reset of delivery and totalization, and a wide variety of digital pulse transmitters permit remote operation and monitoring.

The Neptune design nutating disc measuring chamber is both accurate and dependable, with repeatability of 100% + or - 0.1%. The double case feature reduces the effect of higher pressure losses in measuring viscous liquids. In addition, the disc design permits accurate measurement of liquids with suspended 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 hundred of nonacidic liquids. Threaded end connection allow rapid conversion from right to left hand flow with provided coupling sets. Pulse transmitters, when used 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, combined with continual design improvements, assure a simple to operate and economical to use system proven through more than 100 years of experience. The overall design of the Type S yields a meter with 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 both simple accomplish and requires very little time.

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

Normally assembled as a right hand flow: inlet on left, with outlet on right. Optional left hand flow: inlet on right, with outlet on left requires rotating the register by 180 degrees.
