HOW TO USE
RLBL-C 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. RLBL-C heat meter is consisted of heat meter and its controller, they are in one structure. The meter is consisted of base meter and controller, the controller is consisted 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 the exchanged heat power according to the standard heat calculation formula.
Our heat meter can add M-BUS function, which supported by collector, concentrator and software to realize remote meter-reading system, the wireless function can be also added and consists of remote meter reading system with PDA or other relevant wireless device, with the remote meter reading system, the management center can read meter data and control the user’s power consumption conveniently.
The meter is designed and developed on the basis of the European Standard EN1434 and OIML-R75 International Standard, with high performance and low energy consumption, and in line with the product standard CJ128-2007 Heat Meter issued by Ministry of Construction of China.
FUNCTIONS
1. Alarms when voltage is low.
2. High definition and wide temperature LCD display
3. Flow rate has 8 levels and are separately adjusted, with high precision.
4. Alarms when the temperature sensor is disconnected or has a short circuit.
5. Measuring mechanism has no moving parts and no wear and tear forever. The measuring accuracy will not be influenced by usage period.
6. Optical interface, long distance communication, read meter by PDA.
7. M-BUS communication.
8. Horizontal or vertical installment.

INSTALLATION
1. A filter shall be installed in front of the ultrasonic heat meter.
2. Installing the valve in front of the filter will be convenient for repair and clean the filter.
3. Before installation, please clean the pipe firstly, to avoid that there is stone or other sundries inside the pipe.
4. During the installation, please don’t wrench, move or knock the component inside of the pipe, to avoid knock against the meter body.
5. Please leave enough space for repair. The installation shall follow the water flow direction on the pipe.
6. The heat meter can be installed horizontally or vertically on the water inlet of the pipe. When installed horizontally, two pieces of energy converter must be in horizontal; when installed vertically, they must be installed on the straight pipe with the water flow on up direction.
7. When connects 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.
8. During the transportation process, please handle them with care to avoid knocking and cannot store the meters at strong electromagnetic field.
