More details about the flow meter: F=(5.5*Q)Β±2%, Q=L/Min, error: Β±2% Working range: 1-60L/min Working voltage: DC 5-24 V Water Pressure: ≀1.2Mpa Liquid temperature: 0-100℃ Maximum current consumption: 15 mA(DC 5V) Wire length: 15 cm Size: 72mm x 46mm x 42mm(L*W*H) Refer to the wiring: Red wire: VCC(+) Black wire: GND(-) Yellow wire: Signal output Package: 1 x 1 inch flowmeter Review: I've adapted this Gredia GR-201 1/2" flow sensor paired with a Digiten Flow Meter to monitor flow rate thru a UV sterilizer. The sterilizer I have requires a flow at 37 GPH optimum and 60 GPH max to be effective eradicating protozoa. Out of the box the pairing of the meter and sensor was way off reporting 16 GPH while a had a gate valve nearly closed. So to calibrate it, the meter has a K-factor value that has to be adjusted to the sensor you pair it with. The default was a K-factor value of 1.98. I did a Google Bard search for what the sensors K-factor should be... 11.45. I set the meters K-factor to that. It was much closer but not accurate. I adjusted my valve until the meter was reading 1 GPH of flow. I set up a bucket to divert the water exiting the system into so I could measure the amount dispensed in a minute. I recorded .453 gal. with the K- 11.45. Now a little math, divide the current K- (11.45) by the flow it produced (0.453) while the valve restricted flow with the meter reading 1 GPM. The resulting new K-factor of 25.27 worked precisely. Well, as precise as using a large measuring cup to measure the amount of water dispensed. I re-ran the test, I got 1 gallon at the 1 minute mark, 3 gal at 3 minutes. The one annoying thing about the meter is the backlit display goes dark after 15 seconds. Annoying during the calibration when your hands are busy turning on/off a pump and a timer. But in actual use I'll only be using this to set the gate valve position and the backlighting won't so much be an issue. I hope this helps those trying to get a more accurate reading.
