VE/804 Series Electromagnetic Thermal Energy Meter

The VE804 Series operates based on Faraday's Law of Electromagnetic Induction. As the conductive fluid flows through a magnetic field, it generates an induced voltage proportional to the flow velocity. This signal is converted into volumetric flow data. With dual integrated Pt1000 temperature sensors, the system simultaneously measures the supply and return fluid temperatures, enabling accurate thermal (or cooling) energy calculation in accordance with international standards.

★ High Measurement Accuracy: Class 1 and Class 2 

★ Nominal Diameter Range:
