## Questions & Answers

**Q: What is the K value for this sensor please?**
A: The label on the sensor provides an "F" number that is the Hz for LITERS/minute; my search for a "K" value states that number is GALLONS/minute. A liter is VERY ROUGHLY a little less than a quart, so a K value should be roughly 4 (3.78541) times an F value.

**Q: Is the output PWM or an analog output?**
A: Hello, the output is PWM.

**Q: would i be able to measure the flow through my drip irrigation with this? never measured but I'm guessing it might be less than .3l/min at times**
A: I have three different models of Gredia's flowmeters and I found them to be inaccurate at low flow rates, I presume there is not enough force to spin the wheel ... F = ma.

**Q: What is the output voltage on the yellow wire during .4 lpm flow if fed with 5VDC?**
A: At 5vdc you should get >4.7vdc
