Digital heat meter I-UHM

ultrasonicModbusRS485

Product Overview
Ultrasonic heat meter I-UHM for thermal energy measurement with RS485 (Modbus) output. Designed for water-based and homogeneous liquid systems, the meter calculates thermal energy by combining ultrasonic flow measurement with temperature difference (ΔT) between supply and return. Equipped with PT1000 temperature sensing and long-term data storage, it provides stable, non-mechanical measurement suitable for industrial heating/cooling circuits.
