Flange Type External Float Level Switch

Product Description:

Flange type external float level switches are fully independent units designed for installation on tanks or vessels via threaded, socket weld, or flanged pipe connections. These switches have proven their reliability and repeatable performance in hundreds of industrial applications including petroleum refining, petrochemical production, and power markets...

Applications:

Chemical, Crude Oil Processing, Power, Petroleum Refining, Pulp and Paper

Features:

(1) Carbon steel float chamber;

(2) Stainless steel float and linkage;

(3) Working pressure up to 62 bar (900 psig);

(4) Process temperature up to +538°C (+1000°F);

(5) Specific gravity as low as 0.34;

(6) Internal access to float chamber through top-mounted flange;

(7) Single or multiple switch assemblies;

(8) 1", 1 1/2", or 2" tank process connections available in NPT, socket weld, side-side flange, or side-bottom flange configurations.

Working Principle:

The buoyancy of the process liquid causes the float to ride on the liquid surface. The float moves with changing liquid levels, and this movement brings the magnetic sleeve into the magnetic field of the switch magnet, pulling the magnet toward the sleeve and triggering switch action.
