Product Description

Thermal energy meter is a kind of instrument used to measure and display the released heat when the heat carrying liquid passes through the heat exchange system. The thermal energy meter is consisted of flow sensor, microprocessor and matched pair temperature sensor. The microprocessor gets the flow signal through flow sensor and the signal of water temperature at the entrance and exit from the temperature measuring circuit, and then calculates released heat by the heat carrying liquid according to the standard heat calculation formula. The thermal energy meter is designed and developed on the base of the European Standard EN1434 and OIML-R75 International Standard, and has high performance and flow energy consumption, and accords with the product standard CJ128-2000 Thermal Energy Meter issued by State Construction Department.

Application:

1. Thermal meter should be at best installed at the water exit of the pipe, to avoid pollution, and make it easy for dismantling and card inserting.

2. Thermal meter should be installed horizontally (with the side of display upward), the direction shown by the arrow should be the same with that of the water flow in the pipe.

3. The inlet temperature sensor (line with blue label) should be installed on the joint of the water outlet.

Structure and Features::

1. The flow measurement adopts the latest patent technology of wireless digital monitoring.

2. The flow measurement adopts no mechanic gears, non-magnetic sensor, and wear-proof,

anti-corrosive and anti-attack.

3. Alarms when low voltage and being attacked or destroyed.

4. Alarms when the temperature sensor is disconnected or has a short cut.

5. Flow and temperature has 10 levels and separately adjusted, with high precision.

6. Intelligent reduction of consumption according to the rate of flow.

7. The program can be upgraded online.
