The principle of operation of the water meter of this modification is based on the reception and transmission of ultrasonic signals that pass through the water flow. The device can be used to organize individual metering of water consumption in apartments, offices, industrial plants and commercial facilities. The device does not have modules for remote data transmission, readings are taken directly from the display located on the front panel of the computing unit. The device is equipped with a pulse output that sends pulses to a secondary device that counts the pulses and transmits information to the control center. This allows data to be read without direct access to the device.
