G1/2" Hall Water Flow Sensor USN-HS21TX 1-30L/min Flow Meter Flowmeter Combined with Solenoid Valve All in one Integrated
Model:?USN-HS21TX
Explanation:
Function:?For the sense of the water flow rate on the following equipments:?Thermostatic water heater, water purifier, water dispenser, smart card equipment, coffee machine etc.
Calculation Formula:?F(Hz)=9.7*Q(L/min)
Note:
1. When magnetic material is close with the sensor, its characteristics may vary.
2. In order to avoid particle debris, the sensor must be installed after a filter.
3. The flow sensor installation has to avoid strong vibration and shaking of the environment, so as not to affect the sensor's measurement accuracy.
Features:
1.???????Food grade POM (polyformaldehyde) material, environmental friendly material,?
2.???????Intubation design of inlet and outlet pipe, easy connection and operation;
3.???????Imported Hall IC from Japan, stable and reliable;
4.???????Range: 1-30L/min;
5.???????working voltage: DC5-12V;
6.???????rated voltage: DC5V;

8.???????Pulse output duty cycle: 50+-10%
9.???????Insulation resistance: 100M Ohm and above;
10.???Tightness: Seal up all the holes, and inflate with 0.8MPa water, after 1 minute, no leakage and deformation;
11.???-20-60 centigrade;
Solenoid Valve:
Always closed.
Pressure: above 0.1Mpa.
Input voltage:12V
