JOYS663 Ultrtasonic water meter

タイトルまたは説明

Ultrasonic Water Meter is an ultrasonic flow sensor that measures the velocity of water by using the principle of ultrasound.All measurements, references, readings and calculations are controlled by a microprocessor in the calculator top. The accumulated water consumption is displayed with eight significant digits and measuring unit.

Ultrasonic water meters measure the difference of the transit time of ultrasonic pulses propagating in and against flow direction; The meter is available to be integrated in a wireless network, you can select radio, wireless M-bus and PLC.
