The Rochester Remote Ready Dial, R3D® – LP, is a magnetically-driven, Hall Effect compatible dial. Dials are utilized on stationary applications where direct reading plus an electrical signal to a remote fuel level monitor may be required. Models are available to fit all Rochester Junior style liquid-level gauges.
In the area of LP gas measurement, a magnetic drive feature is important because a magnetic drive allows a signal from the float mechanism inside the tank to be transmitted through a solid bulkhead. The R3D® – LP dial is designed to allow a second magnetic coupling. This is a coupling from the R3D® – LP pointer magnet, through the sealed lens and into the Hall Effect Module (sold separately).
Features
- Highly reliable magnetically driven dial

Warnings
For LP-gas and other flammable product service applications, connect only to circuits and power sources Classified and labeled as Intrinsically Safe for Class 1, Division 1, Group C and D hazardous locations. The connection of non-intrinsically safe power could cause fire or explosion of flammable vapor which may be present.
This sensor is not to be used as the primary means of determining high or low fuel condition. It must not be used in the absence of redundant systems in critical applications where there may be significant safety risk or financial exposure in the event of fuel overfill or fuel exhaustion condition. This sensor is not to be used for tank filling.
