DIGITEN Water Liquid Flow Rate Volume Digital Display Flowmeter Quantitative Controller Counter Liter Gallon

Unit is pretty solid and not hard to use. Make sure you do some testing and set the K constant so that the flow meter can be as accurate as possible. I used the "Quantitative" mode to tweak and test until I'm satisfy with the flow accuracy using a measuring cup to count and check the volume. Happy with the unit. Too bad the temperature sensor is not common thread (BSP or M6, can't remember). Should be including 1/4 NPT for North American market.

Good product. Meter was accurate and worked great.

Setup with the linked solenoid and flow sensor. When I pressed run/start the unit would shutoff which then burnt out the circuit board. Think is more an issue with the solenoid that was supplied. It looks cheap. I will need another controller so hopefully doesn’t happen again

先ずは動画の説明から。50Lで水が止まるように設定してスタート。ディスプレイの一番上の数字が総量ですが、46L過ぎでいきなり50Lの表示になりストップ。このような症状がかなりの頻度で起こります。実は、最初この商品を他のショップで購入したのですが、メーカーに動画を添えて返品を申し入れたのですが、シミュレートすると言った切何の連絡もなしです。最初に買った個体の不良も考えられるので、返品のしやすいAmazonさんで、もう一つ買ってみましたが、同じ症状が出ます。もちろん返品しました。メーカーは不良を認識していると思います。同じ機能の商品が、別のメーカーからも出ています。そちらを試してみます。

I've spent the past few months refining my assembly of a whole house well water filtration system & reverse osmosis drinking water plus ice makers on 2 refrigerators, a sink side spigot & rain barrel top off water feed for our 600 gallon pond.With this flowmeter controller I can measure the feed water side of the RO/DI accurately, used in concert with the DIGITEN 1/4" Quick Connect Hall Effect Sensor Water Flow Sensor Food-Grade Flowmeter Water Flow Counter Meter 0.3-10L/min. to make it easier to determine membrane & pre/post filtration stages effective remaining life.Chose this over a kit as I've no need for solenoid control of the input water, the controller & sensor separately to saved a few bucks.Set up of the controller was fairly straight forward, set up for total usage, alarm function on a count, & visual flow indicator.Take note, the sensor is miswired when ordered separately from the controller.It's an easy enough fix as the jacks are accessable in the plug assembly & can be pressed out to swap positions to work with the controller's harness connector.In this case as noted by other reviewers the black & yellow leads need to swap positions to connect to the proper pins in the not quite correct mating connector.They can fit together but it's not the normal connector as appears to be supplied in the controller kit using the same sensor.Also, the temp probe they provide, is an MALE M8 BSP straight thread, so you'll need an adapter from that to NPT or press on to use it inline. I found one here https://www.amazon.com/gp/aw/d/B07SRVYQBZ.With the sensors installed it seems sensitive enough once the controller is properly calibrated to the right K value for your pressure & flow.Of course it would be great if it had flow sensor granular enough to track product water production.Calibration is pretty straight forward, set a K, decant some water, adjust until the meter display agrees with the decanted volume of water...in my case a K value of 150 was close enough.So now I can track when to swap out filters at 850 gallons & the membrane at 44000, as long as it stays in calibration & the flow meter doesn't fail.Build is decent, display is functional & pretty comprehensive. The case has a hang eyelet, which happily fit over the screw head I used.My opinion so far, is it's a good buy.I'll update in the future if anything changes.
