 The meter operates with ultrasonic flowmeter transducers in combination with  
  temperature sensors for measuring supply water flowrate and the temperature  
  difference between supply water and return water, and then measure and dis-  
  play the heat quality either released or absorbed by the water flowing through  
  an heat exchanger. It can execute flowrate measurement-computation-display  
  integrated functions. Compact in size and small in power consumption (The m-  
  eter can operate continuously for over 10 years with a single battery), the meter  
  is suitable for use in residential building, district heating system and centralized  
  air conditioning system.  
The meter works with ultrasonic flowrate measurement technology and remai-  
   ns unaffected in the presence of any magnet-induced interference and especi-  
   ally inthe case where the water has a high content of impurities. Furthermore, with the use of the meter, the pressure loss of pipeline can be
    reduced to a minimum. The meter can be mounted at any angle in either horizontal or vertical direction.
  In conformity with the National Standard on Heat Meter CJ128-2000.
  The meter falls into 2 different major categories, i.e. the CRL-H series household-use ultrasonic heat meter and the CRL-HL series househ-
  old use ultrasonic heat (cold) meter. As for the difference between these 2 kinds of meters, refer to the following Table.
