Products Introduction Jingyuan intelligent heat meter is used to measure and show water flow that the heat released or absorbed from heat exchange system, installed in the export or entrance of heat exchange loop. It is a integrated intelligent heat meter that measure cold or heat consumption of heating or refrigerated facilities. It is applicable to the urban household heating or cooling measurement and automatic control charges. It can improve management level of the heat-supply enterprises by the way of changing the charge mode from original ‘area based’ to ‘actual amount of used’. Functions and Features 1. Cold and heat measurement integrated. 2. The key components use tungsten steel, corundum, anthrax and other wear-resistant materials. 3. SOC single chip design, high reliability. *******0 Single chip from TI , US, Unique encryption technology, ultra low-power. 5. A number of unique patents , such as multiple access classified data correction , redundant memory technology, special handshaking protocol with information transmission encrypted, Classified state code ecognition technology, etc., makes adequate assurance for the data security. ***** moisture-proof treatment, adapted to harsh environment. 7.High-resolution LCD cycle show of more than *0 types of parameters. ***** installed location can be altered under the different circumstances. *****-beam and single-beam structure, convenient choice for the user. ***** pulse interface. Using process ***** Account: The new user needs account-open and receive card in the management department before usage (heat meter dedicated IC card), management department will enter the user’s information and provide the customer with an equivalent amount of heat or cold quantity according to the payment. The information input the user’ s card through read-write manipulator. ***** Reading: Lifting the protection hood, the IC card mouth shows out. According to panel indication, put the voucher card with metal surface upwards into the IC card mouth along the arrow instruction. While the sound of ‘du’ given out, LCD displays remainder which is the sum of original data and the new purchase. The operation of card reading is over. ***** Up: A new card becomes an old card after the dates put into the meter. ***** reissue: IC cards should be properly preserved by users. If lost, card procedures should be timely taken on at the designated department.
