15mm to 40mm Inline Ultrasonic Btu Meter

The threaded ultrasonic BTU meter UBM250I-T is designed for measuring thermal energy of small area where pipe size is not bigger than 40mm , e.g. apartment, villa, shop, etc. The BTU meter comprises of ultrasonic flow sensor and two temperature sensors, base on flow rate and differential temperature of supply / return water to calculate the thermal energy consumption. The product adopts a design of straight-through pipe, features with high measurement accuracy, low pressure drop, anti-blocking, stable operation and long service life. The product can be widely used in central heating/cooling and district heating/cooling systems for thermal energy measurement of residential, commercial and office building.
