Product Description

By entering your model number, you can make sure that this fits.

The Water Flow Sensor is lightweight, with a nimble outline, a small footprint, and is simple to install. In the rotating part, there are bearings.

Every revolution is accompanied by an electrical pulse from an integrated magnetic hall effect sensor. The hall effect sensor is isolated from the water pipe, ensuring that it remains safe and dry.

DC 5-18 V is the working voltage range.

Waveform of the output signal: square wave, output pulse signal

Waterproof, heat-resistance, pressure-resistance, and cold-resistance are all qualities that can be found

Questions & Answers

How reliable is this product's flow measurement?

I was able to get a score of 1 for accuracy. 5% +/- Because the software and controller you use have a big impact on the accuracy, make sure you use good programming practices and have enough hardware to handle the job.

I'd like to connect it to a 12v circuit and use it to turn on a light when there's a flow. Is it behaving like a witch, or does it require supernatural abilities?

Pay attention to the details. It specifies a working voltage range of 5 to 18 VDC. The output is also clearly stated to be a Square Wave Pulse. br>br>As a result, you must keep a close eye on your pulse. br>In your case, this pulse could be used to light an LED via a BJT or FET. The LED's intensity, on the other hand, would be determined by the pulse's DutyCycle. Flow range: br>br>frequencybr>br>frequencybr>br> Sensor: 30 liters per minute, flow rate: 30 liters per minute Allow compression: Hall effectbr> Pressure of the water Working pressure range: 75 Mpa belowbr> DC 5- Waveform of the output: 18 Vbr> Pulse signal with a square wave as the output. Work with Android and the Raspberry Pi system.

When water flow is detected, will this start and power a 12v RV water pump?

Not in a direct way. However, you can use it as a sensor and then power the water pump by opening and closing a relay. The code for these types of projects is available for free on both the Arduino and Raspberry Pi platforms.

Selected User Reviews For DIGITEN G1/2" Water Flow Hall Sensor Switch Flow Meter Flowmeter Counter 1-30L/min

The specified calibration appears to be off, but everything else works as it should (2% accuracy)

4/5

Only 2 accurate, but the calibration factor is 7. 5hz/(l/min)=450 pulses/liter also appears to be off. I calculated it to be closer to 13 after averaging a few tests. 796 pulses per liter at 25hz/(l/min).

I've been using these as part of an automated rain collection and use system for a long time, and they're great for the price

5/5

I use these to determine when the flow stops and to keep track of tank transfers. They don't like to eat twigs, but what do you expect? They don't always start with high flows, but they're still a great trade-off. The one I took apart (to remove a twig and repair some damage caused by wearing against said twig) was very well built and looks like it would have lasted more or less forever and never leaked if I hadn't eaten something I shouldn't have let in there.

It's working perfectly

5/5

This is connected to an esp32 (flashed with esphome) that communicates with a RPi running Home Assistant and measures the amount of water that flows into our garden. It really works.

Accurate and dependable

5/5

It's a great tool that's easy to use and precise. Added 0. For noise reduction, there is a cap on the input.

There aren't any dead spots on the floor

5/5

I really like this. Unlike magnetic reed switch sensors, this one will not stall in a polarized location, giving the appearance of flow. It's also extremely sensitive to low flows, which a reed switch can't do without a threshold flow.

Garbage Threading is a term used to describe the process of threading garbage through This is a complete mess when it comes to threading

3/5

I tried BSP and NPT threading, as well as Teflon tape, but it still leaked like a sieve.

The calibration formula was incorrect, but I was able to get it to work

5/5

Following my testing and calibration, I discovered that using 6. Rather than 7, use 5, instead. When multiplied by 5, the readings became much more precise. Is anyone with me on this?.
