Household heat meter with radio output

Overview

Household heat meter with radio output "Pulsar IoT" - designed to measure: the amount of heat energy, cooling energy, heat power, volumetric flow (volume), temperature, temperature difference of the coolant (water). To read the data, access to the metering device is not required - the transmission 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. Structurally, heat meters are a single heat meter and consist of:

  • one or two volumetric flow sensors;
  • pairs of resistance thermocouples;
  • one or two gauge pressure sensors;
  • calculator

The principle of operation of the heat meter consists in the processing by the calculator of the measurement signals coming from the volumetric flow sensor (s), temperature sensors, gauge (sensors) of excess pressure, calculation and display on the indicator device of the calculator of the measurement results.
