Magnetic Level Gauges
Magnetic level gauges provide on-site visual indication of liquid level. A bypass tube mounts to the outside of the tank, so the level in the tube always matches the level in the tank. A float with an embedded magnet follows the liquid level inside the tube and transfers it, without contact, to the display on the tube and/or a monitoring device.
Unlike glass sight gauges, magnetic level gauges are not subject to breakage, and they install and maintain easily. Magnetic level gauge products are listed below.
