Ultrasonic apartment heat meter with radio output


Ultrasonic heat meter with radio output "Pulsar IoT" is designed for apartment-based metering of heat energy consumption. It is installed in a horizontal piping system. To read the data, access to the metering device and the presence of the tenant are not required - the transfer is carried out to the dispatching device via a radio channel. Using a radio channel allows you to transmit information regardless of the presence of a cellular signal. The radio module is a self-contained device - it works from a built-in battery.
