DIGITEN Water Flow Control LCD Display Controller+G3/4" Hall Sensor Flow Meter Flowmeter Counter+G3/4" Solenoid Valve Normally Closed N/C+12V Power

Working perfectly to check flow rate on a UV sterilizer attached to my saltwater reef aquarium.I didn't need to use the solenoid valve only the flow meter and thermometer, both worked perfectly and were easy to set up/install. Most difficult thing is setting the proper "K-Value" for accurate flow rate.

Missing the "1 meter adapter cable" to tie the parts together. Guess I'll return the unit and see if I can get a replacement. I'll up the rating to four stars due to very fast replacement. I haven't had time to test it yet, but the equipment looks well made for the price. I have a habit of losing these little instruction books, I wish they would post a PDF copy on line.

Unit is not accurate at all, it's rated to handle 60L/minute and is unable to be accurate even at 20-40L/minute. Overshoots 20-50% with high irregularity so can't even adjust K value to compensate.

I checked this out at home before taking it out to the airfield where I planned to use it to control loading of ballast water into my sailplane. At that time I found out that the pump control output was dead. I have not yet investigated a warranty claim, but I got a simple dc timer to do the same job.

Flow sensor lasted about two weeks and stopped reading.

In this day and age, not having a wireless report of flow rates and the ability to control an emergency shut off valve - makes this produce very limited. Essentially, its a volumetric sprinkler controller.
