LVR20 and LVR30 liquid level sensors have a voltage divider network that incorporates a reed switch array sensitive to the position of the magnetic float.
Float Sensors, also known as float switches, are one of the most widely used and reliable methods for liquid level sensing and monitoring. These devices are used for a variety of purposes, including for liquid level control and monitoring in tanks, sumps, and industrial processes. The most popular type of float switch is the reed switch, which works by sensing the position of a magnetic float. Reed switch float switches are economical and easy to install. They are able to provide accurate and reliable level sensing for many liquids.
Omega Engineering’s float operated continuous level sensors have 316 SS wetted parts, come in ranges up to six feet, and are available with 4-20 mA, or voltage outputs.
