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.
