General Introduction
RLB-F is used to measure and display heat power in pipes. One household with one meter and one IC card for consumer. It is more advanced than RLB since it is prepaid and use RF card to activate meter. It consists of flow sensor, microprocessor and temperature sensors and prepaid programme. It also can be used to measure cold power if connect temperature sensors reversely.
Characteristics
1. Prepaid, RF card, waterproof and reliable performance.

2. Latest patent technology of wireless digital monitoring to supervise and calculate heat power.

3. No mechanic gears and magnetism sensor, wear resistance, anti-corrosive and anti-attack.

4. Alarm when lower or voltage or being attacked.

5. Alarm when temperature sensor is disconnected or on condition of short circuit.

6. Flow and temperature has 10 levels and can be separately adjusted automatically, high accuracy.

7. Smart lower power consumption according to different flow speeds.

8. Update online.

9. Data backup and automatic correction.

10. Ultra-low energy consumption.
