1. Introduction

Hall Effect Flow Sensor

Model:  USC-HS21TC

Explanation:

US: UltiSensor; N: Nylon; C: Copper H: Hall Sensor; S: Straight; 41:G1/4,6mm; P: Plug; T: Threaded; 

E: Elbow; T: Threaded; 21: G1/2’; 43: G3/4”;  A: Type A

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.
