3500 series RF admittance level switchDetailed product description：

The 3500 series RF admittance level switch is a novel level measuring instrument that uses advanced RF admittance technology to overcome the defect of capacitive level meters that cannot eliminate the influence of conductive hanging materials. The instrument has reliable operation, can resist the influence of heavy hanging material layers, and is suitable for almost all industrial sites. The instrument also has the characteristics of easy installation, maintenance free, and low price. Instruments are widely used in industrial fields such as petroleum, chemical, metallurgical, pharmaceutical, power, food, paper, etc.
