What is the K value for this sensor please?

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.

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

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.
