NOHKEN FR21 & OLV-21 Magnetic Float Level Sensor

The FR20 and OLV-20 custom level sensors are engineered and manufactured to meet demanding customers applications for liquid level sensing. Available in a wide range materials and mounting types, these sensors are appropriate in most liquids. The FR20 series is available in lengths up to 3900mm with a variety of mounting configurations. The OLV-20 series is physically smaller and has a maximum total length of 500mm. Interface of two immiscible liquids can be detected by FR series. The difference of SG is required more than 0.1 for SS float, 0.2 for plastic float.
