China Professionally Supplied Wireless Remote Control Lora Ultrasonic Water Meter

Overview
LoRa ultrasonic water meter is intelligent measuring instruments by the temperature sensor (50mm and more), flow sensors and calculators. 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. It can transmit data through LoRa module. And can provide important application and data for many applications in the pipeline.
Mainly used for water metering and monitoring water flow, such as domestic water, central air conditioning systems, equipment, etc
