General Introduction
Samrt Contactless IC Card Digital Heat Meter can measure heat power passed through pipes. It is more advanced than RLB since it is prepaid and use RF card to activate meter. It consists of flow sensor, microprocessor, temperature sensor and prepaid module. 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 technique of wireless digital monitoring to supervise and calculate heat power.
3. No mechanic gears, no magnetism sensor, wear resistance, anti-corrosive and anti-attack.
4. Alarming when low voltage.
5. Alarming when temperature sensor is disconnected or in case of short circuit.
6. Flow rate has 8 levels and can be separately adjusted automatically, high accuracy.
7. Smart lower power consumption according to flow speed.
8. Update online.
9. Data backup and automatic correction.
10. Ultra-low energy consumption.
11. Electric floating ball valve patent technique
