Range: 0-60m Maximum accuracy: 0.1%

The L301 immersion type liquid level transmitter can be used to measure the liquid level in open containers, as well as in rivers, lakes, and water wells. It has the characteristics of simple structure, accurate measurement, and easy installation. The L301 immersion type liquid level transmitter consists of a stainless steel probe, a gas conducting cable, and an electronic transmission unit. The probe of the transmitter is made of 316 stainless steel structure and can be directly inserted into the measured liquid for use. The sensor, which is strictly sealed in a stainless steel probe, is isolated from the measured medium by a 316 stainless steel diaphragm and filled with silicone oil, ensuring wide applicability. The electronic transmission unit is strictly sealed in the electrical box and can also be equipped with Hirschman connectors for easy wiring
