R-30D Pulse Transmitter Batch/Totalizer Register

Brand: Niagara Meters

Transmits a scaled electrical pulse signal (switch closure type) for each discrete unit of liquid volume metered during a batching cycle and continuous digital totalized readings. 

The 6" dial face with gasketed viewing glass display, contains 5 digits to display non-resettable totalization and can be configured to display any standard engineering unit (U.S. gallons, Imperial gallons, pounds, and liters). 

A large sweep hand is located in the center of the register. 

The sweep hand can not be reset.

A microswitch is activated each revolution of the sweep hand. 

The value of the pulse is equal to the range of the dial face. 

Variations are possible by adding lobes to the cam (up to 10) and or changing the range of the dial face. 

Maximum sweep hand speed is 60 RPM.
