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.

Works as expected and very easy to install very helpful if you want to control water flow.

フローセンサだけ使用してます。常に1.3~1.5mpaの圧力のかかるところで少し使用してみましたが、1.5ｍpaぐらいになると使用した量が合わなくなる気がします。とはいえなかなかの圧ですので、逆にいえばそこまでなら安定して使えます。漏れのような少量は検知できないようです。接続は１２ｖ直流で使用してますが電源を切るとログが消えます。ログを残したい場合電池式のほうが良さそう。

Arrived on time and well packaged. Be aware that the thread is British pipe and connectors are hard to find. I used FIP fitting with an added washer and no leaks so far. Early step in set up is to set the K value of the sensor and they do not tell what the K value is of the included sensor. I have messaged them today and am waiting for an answer. The instructions say to contact the manufacturer for the K value, they are the manufacturer so why do they not provide the information that they know you will need.

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.
