Is there any documentation on converting the ppm signal on the yellow wire to liters per minute flow rate? Most other flow meters have this info in the data sheet but I can not seem to find any on this sensor.
I just answered my own question. I must have overlooked the formula in the data sheet. Its ppm/7.5= flow in liters per minute
Can you show us your program?
Yes I am in the middle of a full writeup on the water flow sensor. It should be posted in a day or so. Still refining the code. Something is wrong somewhere. I am using a CPX Pro (jingway 1200) pump from Dangerden.com and its rated at a max of 880 lph and I am getting about 1300lph from the flow sensor. I think it may have a bipolar hall effect sensor inside instead of a unipolar hall effect sensor.
