BTU 2940 - BTU METER – ULTRASONIC INLINE TYPE

BTU 2940 is an Ultrasonic type BTU meter, which is an energy measurement device used to calculate the amount of thermal energy transferred in heating or cooling systems. It measures the energy consumed or delivered by monitoring the flow rate of the heat transfer fluid and the temperature difference between the supply and return lines. It uses ultrasonic in line type flow meter to measure the flow rate.

BTU meters are widely used in HVAC systems, district heating and cooling networks, chilled water plants, and energy management applications.

KEY HIGHLIGHTS
