The iSOLV EFS802 BTU is a complete system that includes a electromagnetic flow meter, a temperature sensor and a matching pair of sensors. The system can detect the temperature in real time at both the supply and the return pipes. It also monitors the flow rate instantaneously based on Heat Exchange Thermodynamics principles. The EFS802 BTU measurement system allows for real-time access to information on various parameters such as temperature, flow rate and energy consumption. The flow meter is designed with a reduced bore, allowing installation of the straight pipe (U0D0).
