With a flow range of 0.15-1.5L/min and a maximum pressure of 1.2MPa, this sensor is perfect for applications like water heaters. Its durable, water-proof design and SGS certified materials ensure reliability and longevity, making it an essential tool for modern water management. ## Description 1. The Water Flow Sensor is light, nimble outline, small size and easy to install. The bearings used in the rotating part. All materials are in line with SGS testing standards.2. There is an integrated magnetic hall effect sensor that outputs an electrical pulse with every revolution. The hall effect sensor is sealed from the water pipe and allows the sensor to stay safe and dry.3. Three wire connection: Red for positive, black for negative, yellow for pulse signal.Specifications:Product Name: Water Flow SensorMaterial: POM(Shell)Liquid Temperature: Not More Than 60CRated Voltage: DC 5VMax Current: 10mA(DC 5V)Maximum water pressure: 1.2MPaFlow Range: 0.15-1.5L/minConnector Size: 1/4Ingress Protection Rating: IP65Connector: Male XH-3PCable Length: 33cmSize: 66mm x 41mm x 24mm(L*W*H)Color: WhiteNet Weight: 28gPackage Included:1 x Water Flow SensorNote:1. Installed in accordance with flow direction in the back of product, otherwise there is no signal output.2. A filter screen must be installed at the inlet of the sensor, in order to avoid particles and debris entering the sensor. Review: Works well if you know how to use it - This flow meter is built well and has not leaked thus far. Like any of the many other hall effect flow meters out there, this is not a "plug and play" solution for measuring flow rate. For use with an Arduino, some coding is necessary in order to use this device. I was able to calibrate this device by taking a known weight of distilled water and letting it flow through the device due to gravity into an empty beaker while counting each "pulse" from the device using one of the digital pins on an Arduino. I made sure that no air was in any of the lines or inside the impeller while running the test, and I stopped the flow before air entered any of the lines. Once stopped, I weighed the leftover water and through subtraction found the exact amount of water that had flowed through the device. This gave a factor of 0.211 mL per pulse from the device, meaning for every time the hall effect sensor changed state from high to low (or vice versa) 0.211 mL of distilled water had moved through it. This can be used to measure flow rate of a liquid- in my case I am counting the pulses in a loop and then once a second has passed I multiply the "mL per pulse" by the number of pulses recorded over that second (pulses per second) which gives mL per second. Review: very susceptible to inductive fields - bought for a flow monitor on a custom RODI manager, sadly I had some bugs I thought were code but were actually that the pulsed output of this device was able to swing WILDLY onder the weak field of a motor that drew 30w to boost pressure I had to move from a 4-inch distance to over 12 inches of distance behind a steel bladder tank just to stop the ghost flow reading, and it still randomly gets a few extra pulses(likely from power line stability they really should have used a stronger pullup internally with teh hall-effect sensor simply grounding the signal locally with a local bypass capacitor given the leads are so thin otherwise works perfectly fine once you realize the pulses are about 1 per 0.2ml(not documented, shame on seller, had to find out from a reviewer) and it is inductively sensitive ## Features - Light weight, small size, easy to install.Hall element is imported, water-proof design to prevent water ingress,The inside of the impeller is inlaid with a stainless steel shaft and is always wear-resistant. - All materials are in line with SGS testing standards. - Three wire connection: Red for positive, black for negative, yellow for pulse signal. - The water flow sensor is applied for water heater, and can be used as flow switch. - Maximum water pressure: 1.2MPa, flow range: 0.15-1.5L/min. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07DM137WT | | Best Sellers Rank | #420,189 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #44,099 in Electrical Equipment | | Date First Available | June 8, 2018 | | Item Weight | 1.58 ounces | | Item model number | a18041200ux0153 | | Manufacturer | uxcell | | Product Dimensions | 5.51 x 3.94 x 1.18 inches | ## Images ![uxcell 1/4" Hall Effect Water Flow Sensor Switch Flowmeter Counter Fluid Meter DC5V 0.15-1.5L/min SEN-HW06K - Image 1](https://m.media-amazon.com/images/I/51ezuUI0D+L.jpg) ![uxcell 1/4" Hall Effect Water Flow Sensor Switch Flowmeter Counter Fluid Meter DC5V 0.15-1.5L/min SEN-HW06K - Image 2](https://m.media-amazon.com/images/I/61Ae9XBdIrL.jpg) ![uxcell 1/4" Hall Effect Water Flow Sensor Switch Flowmeter Counter Fluid Meter DC5V 0.15-1.5L/min SEN-HW06K - Image 3](https://m.media-amazon.com/images/I/61oeCJXYuBL.jpg) ![uxcell 1/4" Hall Effect Water Flow Sensor Switch Flowmeter Counter Fluid Meter DC5V 0.15-1.5L/min SEN-HW06K - Image 4](https://m.media-amazon.com/images/I/41x5QmXP9CL.jpg) ![uxcell 1/4" Hall Effect Water Flow Sensor Switch Flowmeter Counter Fluid Meter DC5V 0.15-1.5L/min SEN-HW06K - Image 5](https://m.media-amazon.com/images/I/51XrJU-nSLL.jpg) ## Questions & Answers **Q: how many pulses per liter?** A: Dear customer, it is 0.15-1.5L/min, 1L water=3779pulse ±10% **Q: does this require a flow meter totalizer?** A: Unnecessary. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works well if you know how to use it *by D***Y on July 30, 2022* This flow meter is built well and has not leaked thus far.
