Products Description
No Moving Parts, high accuracy for years long. No moving components in the flow sensor, avoid long-term abrasion of mechanical parts which may result in inaccuracy measurement and failure of the meter. Such design is also resistant to impurities, therefore no inspections and maintenance are cost-free.
Ultrasonic Water Meter Brass Wireless Remote Apartment
A wireless ultrasonic water meter (LoRa )is an intelligent measuring instrument with a flow sensor and calculators. The calculator used the sensor and through the water of time difference to collect temperature differences and sound waves to complete accurate measurement of water flow.
