Hall Effect Flow Sensor
Model: UL-HS41P

Explanation:
UL: Ultisolar; H: Hall Sensor; S: Straight; 41: G1/4, 6mm; P: Plug E: Elbow; T: Threaded; 21: G1/2'
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)=56*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.
