Ultrasonic Liquid Level Sensor 4-20mA, 0-20m Range Non-Contact Level Transmitter

Ultrasonic Liquid Level Sensor 4-20mA, 0-20m Range Non-Contact Level Transmitter for Water Tank, Sewage, Industrial Use This ultrasonic level transmitter uses non-contact ultrasonic technology to measure liquid/solid levels without direct contact. It features high accuracy (??0.5% FS), automatic temperature compensation, and IP65 protection, making it suitable for sewage tanks, acid/alkali solutions, and industrial silos. Available in integrated, split, anti-corrosive, and explosion-proof versions with 4-20mA output, it works seamlessly with PLC and industrial control systems. Integrated Type: Integrated Ultrasonic Level Transmitter with LCD Display, 4-20mA DC24V, 0-10m Range Split Type: Split Ultrasonic Level Meter with Digital Controller, Non-Contact Level Sensor for Industrial Tanks Anti-corrosive Type: Anti-corrosive Ultrasonic Level Sensor for Acid/Alkali Liquid, 0-10m 4-20mA Explosion-proof Type: Explosion-proof Ultrasonic Level Transmitter for Flammable Liquids, IP65 0-20m Range Specification Key Value Product Name Ultrasonic Liquid Level Sensor / Transmitter Model Options Integrated Type / Split Type / Anti-corrosive Type / Explosion-proof Type Measuring Range 0-1m / 0-2m / 0-3m / 0-4m / 0-5m / 0-6m / 0-7m / 0-8m / 0-9m / 0-10m / 0-15m / 0-20m (customizable) Output Signal 4-20mA (2-wire) / RS485 / Modbus Power Supply DC 24V Accuracy ??0.5% FS (error ??? 2.5cm at 5m range) Resolution 1mm Dead Zone 0.35m ~ 0.6m Operating Temperature -20??C ~ +60??C Pressure Atmospheric pressure Protection Grade IP65 Display LCD digital display (on integrated/split models) Material ABS flame-retardant housing, optional anti-corrosive/explosion-proof versions Features Automatic temperature/sound speed compensation, multi-speed response, anti-interference circuit, non-contact measurement Applications Sewage tanks, acid/alkali solutions, industrial tanks, rivers, reservoirs, silos ?? Mounting Method Installation Notes: The reference plane for measurement is the lower edge of the sensor. The upper limit of the level must not enter the measurement blind zone. When measuring side levels, the feed inlet must be avoided. When installed outdoors, it is best to provide rain and sun protection.
