We are offerng hall effect flow sensor
model: usn-hs21ta
explanation:
us: ultisensor; n: nylon; h: hall sensor; s: straight; 41:g1/4,6mm; p: plug; t: threaded; a: type a
e: elbow; t: threaded; 21: g1/2’; 43: g3/4”; m: female and male thread for inlet and outlet separately; 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)= 8.1*flow rate(q)-6(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.
