The Finetek EF/MEF Series is a line of magnetic level gauges that offer local visual indication, level switch activation, and continuous level gauge transmitter output from a single device. These bypass-style level transmitters are typically mounted on the side of a vessel. The EF/MEF Series uses buoyancy and magnetism principles to function. A magnet-equipped float is located within the bypass chamber, which is attached to the vessel. The liquid level in the chamber tries to equalize with the vessel’s liquid level, causing the float to rise and fall along with the liquid level in the tank.

By attaching visual indicators, level switches, and magnetically activated level transducers to the bypass chamber, the magnet inside the float activates all of them as it moves up and down in the chamber. The EF chamber has a standard ID of 60mm (2.36″), while the MEF mini-unit has a typical chamber ID of 1.18″ (30mm).
