IC card prepaid heat meter
Product Description:
Prepaid heat meters can not only accurately measure the heat consumption in heating facilities, but also achieve heat control. The user purchases heat from the property management department, writes it into the heat meter through the user card, and the valve opens. When the user's remaining heat is 0, the valve closes. The user needs to purchase heat and then reopen the valve before continuing to use heat. It can be installed horizontally or vertically, ensuring accurate measurement. Suitable for places with centralized heating such as ordinary residential buildings, schools, and shopping malls.
Functional features:
1. Prepaid heat meters come with one card per household, allowing for payment before use and automatic valve closure after use.
2. The full Chinese menu displays the heating (cooling) value, inlet and outlet water temperature, temperature difference, cumulative flow rate, and is clear and intuitive.
3. The inlet and outlet pipes can be installed horizontally or vertically, making it easy to use and maintain.
4. Meet the national level 2 accuracy verification standard for heat meters.
5. Compliant with JJG225-2001 Thermal Meter Verification Regulations and CJ128-2007 Thermal Meter Standards, M-bus/RS485 communication output can be selected to achieve remote data transmission and centralized control.
6. The product is equipped with a high-capacity battery with a lifespan of 6 years.
