The ZED-TIDCI-M is a battery powered ZigBee device, capable to count pulses emitted from flow rate meters (water, gas, electricity,…) and to measure the temperature from both the 2 on board NTC inputs. Pulse counters and temperature samples are sent at regular intervals to a gateway of 4-noks products family. Moreover, if temperature sensors are installed into an hydraulic circuit in the inlet and outlet pipes this device can send the difference between them.
