R3D Remote-Ready Dial, Magnetel 4” & 8” – LPG
Rochester Remote Ready (R3D) Dial for LPG/propane gas applications
Application
The Magnetel® Rochester Ready Remote Dial (R3D) is a magnetically driven, Hall Effect compatible dial. These dials are utilized on applications where direct reading plus an electrical signal to a remote fuel level monitor are required. Models are available to fit Rochester 4” & 8” Magnetel® and Taylor 8” Master liquid-level gauges.
General Information & Features
In the area of LP gas measurement, a magnetic drive feature is important because the fluid is stored under pressure. A magnetic drive allows a signal from the float mechanism inside the tank to be transmitted through a solid, non-magnetic bulkhead without the necessity of dynamic seals or pressure-type conductors.
Previous designs of liquid level gauges for magnetically driven dials which produced an electrical output signal had the disadvantages inherent in using variable resistors with a wiper arm contact. There has been a need for a more reliable and simplified design for these LP gas liquid-level gauges that would provide an electrical output related to the liquid level in the vessel.
The Magnetel® R3D Dial is advantageous in that it can be used as a retrofit on existing vessels to provide an electrical output that can be utilized for remote monitoring of tank levels. With remote monitoring of tank levels, distributors of LP gas will be able to more efficiently plan deliveries to various consumers.
