QE-300 ultrasonic level meter / level meter / transmitter 
 I. Product Overview 
 Ultrasonic level transmitter uses the principle of measuring the time difference, measured material height. The product is non-contact measuring instruments, has a strong anti-jamming capability, installation, maintenance, easy to use, more suited to the complex environment of the industrial field. It uses low power, small blind transceiver dedicated ultrasonic sensors, high accuracy and stable operation, with temperature compensation. Can be widely used in electric power, metallurgy, building materials, chemicals, food and other industries, not only the measurement of liquid materials, but also measurable solid materials.
