General introduction
RLBF-C series ultrasonic heat energy meter is consisted of flow sensor, microprocessor and matched pair temperature sensor.
Characteristics
1. Alarms when voltage is low.
2. Automatic data correction technology.
3. Alarms when the temperature sensor is disconnected or has a short cut.
4. High definition and wide temperature LCD display.
5. Flow rate has 8 levels and are separately adjusted, with high precision.
6. Motor-driven float ball valve patent technology
7. Intelligent blockage resistant and valve rust remove technology
8. Alarms by closing the valve when remaining heat power is on limiting level
9. Automatically valve testing technology
10. Ultra-low energy consumption (static power consumption is less than 7uA ).
11. The tube adopts forging technology.
12. Measuring mechanism has no moving parts (means no impeller), and no wear and tear forever. The measuring accuracy will not be influenced by using period.
13. There is optic electric interface, and the communication distance is more than 2 meters, adopt infrared tool can read meter.
14. Easy installation, horizontally or vertically.
15. All-in-one card technology, customers can use one card to control all the Suntront brand meters in household(water meter, energy meter, gas meter and heat energy meter)
