1Mhz high temperature ultrasonic water flow sensor steel flowmeter gland sensor
ith the rapid development of Internet of things technology, the demand for high-performance ultrasonic sensor of ultrasonic intelligent water meter applied in intelligent buildings is becoming more and more obvious. In order to further improve the measurement performance of ultrasonic intelligent water meter, TAIMI has launched a new generation of water meter flow sensor from the perception layer. Compared with similar competitive products on the market, this product has more stable electrical performance and stronger pressure resistance. At the same time, it has the characteristics of high sensitivity, fast reaching the peak value and easier signal processing, which helps to improve the measurement accuracy of ultrasonic water meter, and provides a more competitive hardware basis for the iterative upgrade of ultrasonic intelligent water meter.All copper material, high temperature resistance 130 degrees.
- Conform to international potable water standards
- High and low temperature resistance, high pressure resistance
- High stability and reliability
Ultrasonic flow sensor, the core element of ultrasonic flow meters, is a liquid-medium sensor.It can be used in liqiud flow meter, hot meter or as liquid level sensor.
