A: non-contact. B: built-in intelligent temperature compensation circuit, material level, liquid level, ranging, send a meter to complete. C: The ultrasonic level meter has built-in signal sub-plate processing unit to automatically eliminate false signals and ensure the data is true. D: Using multi-point emission circuit, the measurement result is more reliable, and the difficult problem of inaccurate level measurement is solved. E: Ultrasonic level (material place, liquid level)meter, is a non-contact, high reliability, cost-effective, easy to install and maintain level measurement instruments. It does not have to contact medium and it can meet most of the requirement of level measurement, the new generation ultrasonic level meter is developed through our company's many years' efforts and our company own the completely independent property rights of it., Manufacturer: CFWWSAQ
