Heat Flow Meter for Radiator

Heat Energy Meter   General Instruction Digital Electronic Heat Energy meter can measure heat power passed through pipes. It consists of flow sensor, microprocessor and temperature sensor. Microprocessor obtains flow signals through flow sensor and signals of water temperature at the entrance or exit by temperature measuring circuit, and then it will calculate the released heat power by heat-carrying liquid according to the standard of heat calculation formula. It also can be used to measure cold power if connect temperature sensors reversely.   Characteristics 1. Latest patent technique of wireless digital monitoring to supervise and calculate heat power. 2. No mechanic gears, no magnetism sensor, wear resistance, anti-corrosive and anti-attack. 3. Alarming when low voltage. 4. Alarming when temperature sensor is disconnected or in case of short circuit. 5. Flow has 8 levels and can be separately adjusted automatically, high accuracy. 6. Smart lower power consumption according to flow speed. 7. Update online. 8. Data backup and automatic correction. 9. Ultra-low energy consumption.    Technique Specifications
