HOW TO USE
RLB-F smart prepaid mechanical heat meter is a kind of instrument used to measure and display the released heat power when the heat-carrying liquid pass through the heat exchange system. It consists of flow sensor, microprocessor and matched pair temperature sensor. The microprocessor gets the flow signal through flow sensor and the signal of water temperature at the entrance and exit from the temperature measuring circuit, and then calculates exchanged heat by the heat-carrying liquid according to the standard heat calculation formula.
RLB-F has prepaid function and with the supporting of Smart Meter Management System, it provides a new way of heat power management. It provides many benefits to both heat power companies and end users, including guaranteed payment and arrears collection, extensive management tools through detailed report functionality and the ability for customers to manage their consumption more easily.
RLB-F is designed and developed on the reference of the European Standard EN1434 and OIML-R75 International Standard, with high performance and low energy consumption, and in line with the product standard of CJ128-2007 Heat meter issued by Ministry of Construction of China.

INSTALLATION
1. A filter shall be installed in front of the ultrasonic
heat meter.
2. Before installation, please clean the pipe firstly, to
avoid that there is stone or other sundries inside the pipe.
3. During the installation, please don’t wrench, move or
knock the component inside of the pipe, to avoid knock against the meter body.
4. Please leave enough space for repair. The installation
shall follow the water flow direction on the pipe. The heat meter is installed
horizontally and easy for checking and swiping card.
5. When connect the meter with the pipe, please don’t use
excessive force, to avoid damage the sealing rubber mat, and it may cause the
water leakage.
6. During the
transportation process, please handle them with care to avoid knocking and
cannot store the meters at strong electromagnetic field.
