Rochester 6300 Magnetel Liquid-Level Gauges


The 6300 Series Magnetel liquid-level gauges are designed to accurately determine the percentage of total tank volume for most liquids in stationary-storage applications. UL listed for LP Gas and NH3 service.

General Information and Features

These Magnetel Gauges are available in four basic models:

  • Model 6336:
    Incorporates 4" [100 mm] dial and is designed for top mounting.
  • Model 6360:
    Incorporates 8" [200 mm] dial and is designed for top mounting.
  • Model 6339:
    Incorporates 4" [100 mm] dial and is designed for side, end or angle mounting.
  • Model 6342:
    Incorporates an 8" [200 mm] dial and is designed for side, end or angle mounting.

The large, easy-to-read dials are also easy to remove and replace. Materials of construction vary depending on the types of liquids to be gauged. Many different optional features are available to meet your specific needs. These materials and options, along with their pricing impact, are summarized for each model in price list 6300.

Magnetel gauges are designed for working pressures ranging from atmospheric to 450 [31 Bar] psig.
