200KHz Ultrasonic Sensor Ultrasonic Transducer for Gas Flow Meter (FBELE)

Product Description

A gas flow meter comprises a meter body, a tube, and a sensing unit. The sensing unit includes a base connected with one end of the tube; a speed transducer penetrating the base; a temperature transducer penetrating the base; a temperature compensator penetrating the base; and a microcontroller accommodated inside the meter body. The microcontroller is electrically connected with the speed transducer, the temperature transducer and the temperature compensator. The temperature transducer only functions to detect the temperature of the surrounding gas. The temperature compensator only functions to compensate the speed transducer for the temperature drop thereof. Each of them functions independently. Once the temperature of the speed transducer lowers, the temperature compensator directly compensates for the temperature drop, whereby the statistic error value is effectively decreased.
