External Ultrasonic Liquid Level Control

     Welcome to purchase high precision external ultrasonic liquid level control,Website:http://www.smagall.com, non contact explosion proof ultrasonic tank level controller, non contact explosion proof ultrasonic tank level sensor, non invasive ultrasonic explosion proof liquid level switch, non invasive ultrasonic explosion proof liquid level control, non invasive ultrasonic explosion proof liquid level controller from Smagall.     The External Ultrasonic Liquid Level Control is a new type of liquid level monitoring and alarming instrument. The high frequency ultrasonic pulse produced by the probe of the liquid level switch  can pass through tank wall and transmit between the tank wall and the liquid and then be reflected back. By detecting and calculating the reflective behavior, the level switch  can identify whether there is liquid at the monitored position. The liquid level switch  can send relay signal to succeeding devices or other equipment at the mean time, which can realize the function of simultaneous monitoring or controlling. Your Benefits:1. External measurement to ensure maximum safety2. High precision and quick reaction 3. Very Safe to measure dangerous liquid( No opening or penetration of tank wall)        applicable to virulent, highly corrosive or high pressure liquid and liquid in        various complicated operating condition or explosive gas atmosphere. 4. Very easy to install         When the switch is installed the tank can still be in use which means for        installation the tank need not be cleaned beforehand and welding or drilling        on the tank wall is not needed. 5. No need to calibrate regularly. 6. Reliable and stable performance. 7. No need to maintain. 8. Long working life9. Intelligent and electronic 10.
