I use it on my radiant concrete floor "electric boiler" to check and set flow in each circuit. Even though I have flow valves, checking flow with this type meter is much more accurate and quicker. My resulting floor temperatures are identical and the flow matches the engineering calculations. I didn't realize it comes with a flow sensor (lets the boiler know there is water moving in the system and also a temperature sensor. Very good and complete product that works! Review: Using with a reef aquarium to control flow thru a UV sterilizer - I've adapted this unit paired with a Gredia GR-201 1/2" flow sensor to monitor flow rate thru a UV sterilizer. The sterilizer I have requires a flow at 37 GPH optimum and 60 GPH max to be effective eradicating protozoa. Out of the box the pairing of the meter and sensor was way off reporting 16 GPH while a had a gate valve nearly closed. So to calibrate it, the meter has a K-factor value that has to be adjusted to the sensor you pair it with. The default was a K-factor value of 1.98. I did a Google Bard search for what the sensors K-factor should be... 11.45. I set the meters K-factor to that. It was much closer but not accurate. I adjusted my valve until the meter was reading 1 GPH of flow. I set up a bucket to divert the water exiting the system into so I could measure the amount dispensed in a minute. I recorded .453 gal. with the K- 11.45. Now a little math, a divide the current K- (11.45) by the flow it produced (0.453) while the valve restricted flow with the meter reading 1 GPM. The resulting new K-factor of 25.27 work precisely. Well as precise as using a large measuring cup to measure the amount of water dispensed. I re-ran the test, I got 1 gallon at the 1 minute mark, 3 gal at 3 minutes. The one annoying thing about the meter is the backlit display goes dark after 15 seconds. Annoying during the calibration when your hands are busy turning on/off a pump and a timer. But in actual use I'll only be using this to set the gate valve position and the backlighting won't so much be an issue. I hope this helps those trying to get a more accurate reading. ## Features - QUANTITATIVE CONTROL, Controller will turn off the solenoid valve automatically when flow reach to the setting value you desire - MONITOR FLOW RATE, Display the REAL-TIME volume of liquid which passes per minute - WORK WITH ALL HALL EFFECT FLOW SENSOR, It can work various different flow sensor through adjust the K value - WATER METER, DFC15 can be used to measure the volume of water - LARGE LCD DISPLAY, Displays the flow total volume, flow rate and sense temperature clearly; custom icons on the display indicate the controller working status at a glance ## Technical Specifications | Specification | Value | |---------------|-------| | Best Sellers Rank | #134,290 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #103 in Flowmeters | | Customer Reviews | 4.2 out of 5 stars 64 Reviews | ## Images ![Water Liquid Flow Rate Volume Digital Display Flowmeter Quantitative Controller Counter Liter Gallon - Image 1](https://m.media-amazon.com/images/I/61vipNy8DKL.jpg) ![Water Liquid Flow Rate Volume Digital Display Flowmeter Quantitative Controller Counter Liter Gallon - Image 2](https://m.media-amazon.com/images/I/615JFYY5IxL.jpg) ![Water Liquid Flow Rate Volume Digital Display Flowmeter Quantitative Controller Counter Liter Gallon - Image 3](https://m.media-amazon.com/images/I/61UUaYVLH8L.jpg) ![Water Liquid Flow Rate Volume Digital Display Flowmeter Quantitative Controller Counter Liter Gallon - Image 4](https://m.media-amazon.com/images/I/7167mY2edFL.jpg) ![Water Liquid Flow Rate Volume Digital Display Flowmeter Quantitative Controller Counter Liter Gallon - Image 5](https://m.media-amazon.com/images/I/517iIPvuOzL.jpg) ## Questions & Answers **Q: The connector to the flow meter has a brown, white, and yellow wire. Which wire is positive, which is ground, and which is the signal wire?** A: What model flow sensor? The wiring harness has white, yellow & brown... Brown is VCC+ (positive battery). White is ground. Yellow is pulse input to the meter (from sensor). I mainly use the FL-408 sensor, but have others as well. It has red, black, & yellow wires. Red is positive power, black is ground, yellow wire is square wave pulse output from hall effect sensor. Other models have different coloured wires.. You could safely take the cover off the hall effect sensor and check, but easiest to simply plug the mating connectors together *between the sensor and the meter, and "follow" the wires across. **Q: could you use it just to monitor water flow and not hook up a solonid valve** A: Yes, I have it setup to monitor water flow only and have several hook up points, so I can move the meter to any of those sensors. **Q: Just received this product and it appears to attempt opening the solenoid at 12.2vdc and then trips my digiten lfc? is this a shorted solenoid?** A: Possibly! Test the solenoid separately. Try using a separate 12VDC Power supply rated at least 2 Amp DC, and measure the current draw switching it on and off. The solenoid is not polarity dependent, so the wires will go either way. Depending on the solenoid type (There are a few), it may dray 2 Amps by itself, (more on "inrush curent"), in which case you may be overloading the plug pack that came with the DFC15. These are only rated at 2A!Also, listen to the solenoid. You should hear it "click" and if you have it in your hand, - you should feel the impulse of the solenoid. I have found a couple of solenoids that have been poorly assembled and "jammed", and have been able to fix them simply by re-assembling. I found another fitted with a 24V coil instead of the 12VDC coil. (Another cheaper version of the Liquid Flow Controller uses a 24VDC Power supply). Unlikely, but not impossible that the 12VDC driver output within the DFC15 is faulty. It sources its supply voltage from the incoming DC from the socket input, filtered with an electrolytic capacitor (that assists with the inrush current for the solenoid), then "switched" with an output driver transistor. Very simple output driver circuit, but all surface mount, so not easily serviceable. **Q: Can this be rigged in some way as z-wave/smart home compatible controller to use with an econet controls bulldog valve robot?** A: Highly unlikely. The Digiten controllers do not have a comms interface. The manufacturer does not supply any form of technical documentation. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Has it all *by J***M on January 26, 2025* after setting the K factor ( constant needed for the sensor) and verifying the proper volume reading this meter works perfectly.

Documentation not so much. *by R***T on January 13, 2020* I found the Digiten DFC15 Liquid Flow Controller to be well made. Physically and electronically, installation was straightforward and easy. The unit functions well and appears to be fairly accurate. The only issues I had were with the documentation. Firstly, there is no identification of the sensor wires. I'm sure that if you had a Digiten sensor, it would just plug in and you wouldn't need to know which wire was ground, positive or sensor output. However, I spent a lot of time finding a hall-effect sensor with NPT threads and I needed to know this. I figured it out with a multimeter and trial-and-error (Yellow is sensor out, White is ground and Brown is positive). Secondly, while the instructions tell you how to change the "K" parameter, which adjusts the pulse per gallon or liter setting, there is no formula for figuring out what it should be. I read in a product question that the formula was pulses/60. This turned out to be wrong, at least in my case. My sensor information said it produced 1380 pulses per gallon and again, through trail and error, I determined that my "K" value was 4.60. That's 1380/30. I verified this by filling a gallon container and seeing the meter read 1.00 gallons. I did read the manual carefully, in order to discover how to set the readings to Fahrenheit and gallons, as well as how to do a reset. I've used the unit for a few days now and it works perfectly. So other than some better documentation, I'd highly recommend it. ## Frequently Bought Together - DIGITEN Water Liquid Flow Rate Volume Digital Display Flowmeter Quantitative Controller Counter Liter Gallon - GREDIA 2" Water Flow Sensor Food-Grade Switch Hall Effect Flowmeter Fluid Meter Counter 10-200L/min - GREDIA 1/4" Quick Connect Water Flow Sensor Food-Grade Switch Hall Effect Flowmeter Fluid Meter Counter 0.3-6L/min --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tw/products/69174500-water-liquid-flow-rate-volume-digital-display-flowmeter-quantitative-controller](https://www.desertcart.tw/products/69174500-water-liquid-flow-rate-volume-digital-display-flowmeter-quantitative-controller) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-06-01*
