Ultrasonic level transmitter is microprocessor controlled digital level meter. Ultrasonic pulses generated by the sensor (transducer) emitted in the measurement, the surface acoustic wave after reflection by the liquid receiving same sensor or an ultrasonic receiver, by a piezoelectric crystal or a magnetostrictive device into an electrical signal by transmitting and receiving sound waves to calculate the time between the sensor surface to the distance measured liquid. As a result of non-contact measurement, measured media is almost unlimited, can be used to measure the height of a variety of liquid and solid materials. Features Measure range:0 ~ 50mBlind zone:＜0.3-2.5m（different for range）Accuracy:1%F.SPower supply: 24VDC (Optional: 220V AC+15% 50Hz)
