R-31C Electric Contact Batch/Totalizer Register

Brand: Niagara Meters

Provides electrical contact closure upon completion of 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 is set at the zero position by a hand set knob and manually re-set for each batch. 

When the dial hand reaches the fixed quantity setting, the switch is activated. 

The dial hand indicates the quantity remaining to complete the batch.
