1. Magnetic Level Gauges

With over 200,000 installations worldwide, the KM26 Magnetic Level Gauge has provided custom engineered solutions to liquid level applications in industries such as: Oil and Gas, Refinery, Chemical, Petrochemical, Power Generation and many more. The KM26 MLG has proven itself to be a safe, reliable, maintenance free solution for total and/or interface level detection in toxic, corrosive, high pressure, and high temperature processes.

ABB offers the standard KM26 Magnetic Level Gauge with a chamber of virtually any non-magnetic material, extruded process connections, a custom engineered float and all accessories with 316 stainless steel construction. The ABB MagWave dual chamber redundant level system has a proven record of improving feedwater heater reliability in power plants around the world. The MagWave combines a highly visible magnetic level indicator with the precise level measurement of a guided wave radar transmitter. Redundant level control can be achieved by adding a magnetostrictive transmitter or switch to the float chamber.

2. Magnetic Level Gauge Switches

ABB's magnetic level gauge switches for point level alarm and/or control can mount to a KM26 magnetic level gauge or an LS Series cage level switch.

These switches are completely isolated from the process fluid as they are magnetically activated by a magnet equipped float (KM26) or attraction sleeve (LS Series). The unique magnetic coupling action eliminates seals, diaphragms, springs, and torque tubes common to other level switching alternatives since there is no physical contact with the process fluid. The magnetic coupling also eliminates process connections to the switch; therefore, no isolation valves are required to block off the switch for maintenance. The switch "set point" is easily adjustable without changing any process piping and the result is a more reliable and easier way to maintain level system.
