Introduction:
Measuring calorimeter figures out the quantity of used heat based on the temperature of water inlet and outlet as well as water that flows through it, which can be applied to the household metering management of heat and cool energy of central heating and cooling system (air conditioners and chilled water system) in cities and towns.
Ic card calorimeter mainly consists of flow sensor, temperature sensor, calculator and electric valve. It realizes the measuring and charging control of calorimeters. When there is no energy in the calorimeter, ic card calorimeter will immediately close the valve system. The valve will open automatically as soon as the ic card calorimeter is charged by the user.
Functions:
1) measurement and deduction function: when there is flow rate and temperature difference, ic card calorimeter will measure and deduct the actual heat accurately. When there is no any heat, the ic card calorimeter will close the valve system, and meanwhile, the cumulative amount in the ic card calorimeter will be added.
2) display function: varieties of status and data in the ic card calorimeter can be shown circularly through the keys in the lcd.
3) prompting function: error prompt is available when eeprom, clock, and temperature sensor go wrong or when mistakes and problems occur, such as no calibration temperature, abnormal valve and wrong operation etc..
4) prepaid and charge for heat consumable function: the calorimeter will add the heat purchased to the original and display the current remaining amount after the charged user card has been inserted. Heat will be supplied when the valve is turned on. When there is no heat, the calorimeter will close the valve automatically and cut off the supply of water.
Introduction:
Equipped with our companys code controller, base meters are bought abroad to realize the prepaid and control functions, thus to achieve the automatic control of different functions of this new type of gas meter.
Range of application:
This product can be applied to the measurement of gas, natural gas, liquefied petroleum gas and other non-corrosive gases in the city.
Main features:
Automatic prepaid function: charging before using of it, water meter residual capacity= the original gas + newly purchased gas auto-control function: switching the gas path automatically according to the payments and gas situation.
Real time computation function: measuring on the real time and display the stock value, closing gas source automatically when the purchased gas is used up.
Power-down memory function: solid state recorder is internally installed and the data will be permanently preserved.
Status display function: displaying the amount of newly charged gas, the remaining stock and cumulative use, as well as low-voltage state etc.
Prompting function: warning when the remaining gas is used to the set value or other functions are out of work.
Overdrawing function: able to set a certain overdraft gas according to the user needs
Automatic alarm function: when the voltage is lower than certain point, alarm system will be operated and the battery must be replaced within 72 hours, otherwise, it will automatically shut down the gas resources.
Anti-gas-larceny function: shut down the gas supply automatically when there are theft of gas or illegal operations

Introduction
The series of products are encoded and decoded by a computer algorithm based on encryption and decryption rules. The user inputs the 8-bit code that produced by the management system to realize the purchases recharge. On account of using a plain language input with no carrier, the user can go to the places designated by operating companies to buy code directly or get the code by phone.
With 8-bit password, the users can recharge by themselves without considering time and space constraints, and it is simple and convenient to use. Operating units can manage hundreds of thousands of users with little manpower and equipment, and complete manage service fees and charges without leaving home, which puts an end to the phenomenon of the arrears.
