central air-conditioning meters
adopts digital temperature sensor
CKN seriesf central air-conditioning energy meter
CKN series of central air-conditioning meters adopts digital temperature sensor, the temperature accuracy is improved to 0.5 degrees, the sensor line can be increased to 20 meters in length, using not easily blocked insert flowmeter, electromagnetic flowmeter or ultrasonic flowmeter is more suitable for central air conditioning measurement actual situation.
CKN series of central air-conditioning meters cost is high, it is mainly applied in the different paid subjects, needs stratification,partitioning of the integrated building,air conditioning with independent accounting workshop within the factory and the energy metering box with vav air conditioning box .
Such as: shopping malls, cinemas, restaurants etc.

Functions
1. Use the energy exchange of thermodynamic properties directly measuring, the principle is clear and easy to be understand.
2. On site displays: it can directly show the total energy consumed by the user, central air conditioning supply /return water temperature and flow data, intuitive and convenient.
3. RS485 communication port ,coutput the remote concentration meter reading.
4. the control port: can be realized to control the open or close of the electric valves
5. 220V Power supply directly, sustainable power for 12 hours by follow-up battery, with power-down protection, data never lost.
6.Partition measurement, and fewer installation of the measuring equipment points.
