Calorimeter

Production description:

 

   Calorimeter is used in the individual measuring fee of the calorie for the central heating of the construction,

   central air conditioner,cold and hot united supply etc.

   Easy installation:could be installed on the inlet pipe, return pipe at will: the intergraph could spin 360 degree

   horizonally, 90 degree vertically.

The instrument applies all Chinese character display, which is clear and visible, possessing multifunctional

display: calorie value, inlet temperature, return temperature, temperature differential, accumulate flow, flow

velocity, low-voltage alarming.

The instrument applies the design of low power consumption, guaranteeing the lithium battery working for

no less than 6 years, and maintaining the power-down data for 10 years.

Calorimeter applies the technology of American Wegen transmitter and Germany non-magnetic transducer,

which increase the stability and accuracy of the meter, especially for the small flow.

Possessing telemetering function, being able to realize ‘485” or m bus centralized collecting.

 

Feature:

 

  • Using high-quality transducer and advanced electronic measurement technology to ensure high accuracy and stability of the flow measurement

  • Using AD-PFE coating solves the problem of scale affect the life of the calorimeter

  • Can be replaced online communication module, supports M-BUS bus, RS485 bus and remote data transmission pulse output interface,centralized control

  • Automatic error diagnosis function, in a non-normal state, an error message prompts, to ensure safe and accurate operation

  • Calculator meter can be installed horizontally or vertically. Arbitrarily adjust the viewing angle for easy reading

  • Battery life more than 9 years

  • Hot and cold dual-use (heating, cooling can be metered)

  • Optionally into the return pipe installation, ease of construction

  • Can be horizontal or vertical installation

  • Protection : IP68
