Ultrasonic Contactless IC Card Heat Flow Meter
General introduction
RLBF-C series heat flow 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.
