Ultrasonic Water meter 1/2″ with Modbus

$250.00 $115.00


An Ultrasonic water meter is an intelligent measuring instrument with 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. 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.
