The LS7000 is an excellent general purpose level control device. It can sense all liquids and the "difficult to measure" dry materials.
Operation: The probe uses a radio frequency balanced impedance bridge to detect the presence or absence of a product. Upon contact with the product, the probe's frequency is altered therefore signifying the presence of the product. The probe is supplied with an adjustable delay on or delay off timer. The timer is used to ignore wave action in a tank or control a pump using a single probe.
