The Magne-Trac product line provides one of the safest and most economical ways to meet your level measurement requirements.

In applications for extreme pressure, temperature, vibration, and highly corrosive or hazardous material, Magne-Trac gauge will perform where other fail. Features include lower installation costs, easy to read liquid level indication, and low maintenance.

Constructed of non-magnetic materials including standard 316 SST. Exotic materials such as Alloy

20 & Hastelloy C are available. Traditional inlet & outlet mounted design displaying liquid level to match the vessel level. Complete with flange end closure for accessibility to float. Magne-Trac chambers are available to ASME 31.1 and 31.3.

Specifications

Magne-Trac Chamber

The chamber may be constructed of any non-magnetic material, including austenitic stainless steel, alloys such as Alloy 20, and plastics. The chamber is typically mounted to the side of the vessel with an inlet and outlet that will allow the liquid level in the chamber to match the liquid level in the vessel, in the same manner that traditional sight glasses work. Magne-Trac chambers are available to ASME 31.1 and 31.3, and utilize flange end closures for float access.

Magne-Trac Float

Standard floats are constructed of thin wall, deep drawn 316 Stainless Steel or Titanium. Optional materials are available. Each float is custom engineered for a specific application and operating process variables. The float houses a magnet array, designed to project a magnetic field through the chamber and to an externally mounted indicator assembly. Variables considered in the construction of a float are dependent on the temperature, pressure, and liquid density, as well as material compatibilities.

Magne-Trac Indicator

The standard indicator consists of anodized aluminum housing, rotating flags, and a clear cover. The standard UV stable Yellow/Black flags are uniquely constructed of high temperature molded nylon. The non-corrosive nature of the material eliminates problems with corrosion often encountered with aluminum flag/stainless steel pins most commonly supplied in the market. Magne-Trac indicators are constructed with a UV scratch resistant polycarbonate window as standard, eliminating nuisance breakage of glass and allowing a high integrity fit. The flags are a wide 1.4″ to enhance viewing. Each flag is assembled around a high temperature rare earth magnet assembly that ensures a latching action to eliminate false indication due to a vibration.
