Ultrasonic Flow Sensors 1 MHz

Part Number: SMFM21971MH

Easy to mount and solder. Low power consumption, excellent for long-term uses with consistent performance.
Advanced structural design, high distortion resistance.
It can be used as a liquid flow meter or as a liquid level sensor. The enclosed design of the product’s case allows for directly contacts with the liquid while preventing the performance problem usually created by mounting.
