Overview
The Inventory Master’s High- Perfection Ultrasonic Heat Meter with LoRaWAN and NB-IoT is a high-precision heat meter designed to measure and display heat energy as water flows through a heat exchange system. This device calculates and shows the release or absorption of heat energy based on the flow quantity from the flow sensor and the temperature signals from the inlet and return flows using matching temperature sensors, taking into account the water flow over time. It supports LoRaWAN and NB-IoT wireless communication, features IP67 protection, offers a battery life of six years or more, and provides Class 2 accuracy, making it suitable for both heating and cooling systems within a temperature range of 5 to 95 °C.
