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 ## Customer Reviews ### ⭐⭐⭐⭐ Good *by E***O on October 8, 2025* Functions well, but does not come with technical specs. ### ⭐⭐⭐⭐⭐ Great product! *by R***O on October 26, 2020* Works Great!
