Featuring a Hall effect sensor with a square wave pulse output (450 pulses/liter), it supports a wide DC voltage range (5-18V) and operates reliably under pressures up to 1.75 MPa. Waterproof and temperature resistant, it integrates easily with Android and Raspberry Pi systems, making it ideal for smart water management and automation projects. ## Description Waterproof,Heat resistance,pressure resistance,cold resistance.

Flow range:1-60L/min Maximum current:15 mA(DC 5V) Working voltage range:DC 5-18 V Load capacity:about 10 mA(DC 5V) Operating Temp:0-80℃,Operating humidity:35%-90%RH Allow compression:Water pressure 1.75 Mpa below Insulation resistance:>100M OHM Storage Temperature:-25-80℃ Storage humidity:25%-95%RH Output Waveform:Square Wave,output pulse singal. ROHS Compliant. Cable length:15cm. Packaging include G1" Flowmeter x 1 Review: Works fine but restricts the flow - Excellent for the price, but it it has its limitations. As other reviewers wrote, it restricts the flow. I wouldn't want to use it if a water line larger than 1/2 inch is needed. Calibration appears to be within about 5% from 0.5 gpm to 4 gpm. Below 0.5 gpm calibration falls off quickly. I showed an 18% error at 0.38 gpm. I didn't test it above 4.28 gpm which is all I got through my 1/2" hose. Review: works well for my application - It works well for my application. I set up a solar water heater for my pool controlled by a Raspberry Pi. I am using it to provide relative flow rates while making minor adjustments to the actuator/valve, so I can provide a variable flow that is always a constatnt temperature higher than my pool temp. Not sure how accurate it is, but I do know that the value of 450 pulses/liter for the 1" as stated in the ad is not correct . If F=4.8 * L/M, then pulses/liter should be 4.8*60 or 288 which is the value that I am using, but I still suspect it is too high. Will have to write some code to allow me to calibrate it. Had it in my system for about a month now, no complaints Update 6/4/2018. After adding 2 more solar panels, I am getting a max flow rate of 45 liters/min. Still running fine. but does deveop a louder hum at the higher flow rates. In addition at this increased flow rate I believe that it may have become a bottleneck considering the pump size that I am using to pump the water up around 25 feet to the solar panel. ## Features - Flow range:1-60L/min, Sensor: Hall effect. - Allow compression:Water pressure 1.75 Mpa below - Working voltage range:DC 5-18 V - Output Waveform:Square Wave,output pulse signal. - Work for Android and PI system. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01EA3C6LS | | Best Sellers Rank | #328,837 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #52 in Flow Sensors #4,679 in Electrical Switches & Dimmers | | Brand | DIGITEN | | Customer Reviews | 4.0 4.0 out of 5 stars (59) | | Exterior Finish | Copper | | Inlet Connection Size | 0.5 Inches | | Inlet Connection Type | National Pipe Tapered | | Is Discontinued By Manufacturer | No | | Item Weight | 2.82 ounces | | Item model number | FL-808 | | Manufacturer | DIGITEN | | Material | Metal | | Maximum Operating Pressure | 1750000 Pascal | | Number of Ports | 1 | | Outlet Connection Size | 0.5 Inches | | Outlet Connection Type | Compression | | Package Dimensions | 6.54 x 4.53 x 1.77 inches | | Specification Met | RoHS | | UPC | 713458679482 | ## Product Details - **Brand:** DIGITEN - **Exterior Finish:** Copper - **Inlet Connection Size:** 0.5 Inches - **Inlet Connection Type:** National Pipe Tapered - **Material:** Metal - **Maximum Operating Pressure:** 1750000 Pascal - **Number of Ports:** 1 - **Outlet Connection Size:** 0.5 Inches - **Outlet Connection Type:** Compression - **Specification Met:** RoHS ## Images ![G1" Water Flow Hall Effect Sensor Switch Flow Meter Flowmeter Counter 1-60L/min - Image 1](https://m.media-amazon.com/images/I/614zhs50-IL.jpg) ## Questions & Answers **Q: where do i get the matching male connector?** A: Sorry for the delay, I found them on Flexpvc. comQuantity: 2Product: BS435-010 Female Adapter 1 inch BSPT x 1 inch slip socket.

Unfortunately it failed at 11.5 months with minimal use. When starting the flow it rattles around until the paddle wheel gets stuck. I need very low flow rates so it still flows water for me, but I wouldn't buy again. I'll have to drain the system to eliminate this part at some point. ## Frequently Bought Together - DIGITEN G1" Water Flow Hall Effect Sensor Switch Flow Meter Flowmeter Counter 1-60L/min - DIGITEN Water Flow Control LCD Display+G1 Flow Sensor Meter --- ## 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.nz/products/407516097-g1-water-flow-hall-effect-sensor-switch-flow-meter-flowmeter](https://www.desertcart.nz/products/407516097-g1-water-flow-hall-effect-sensor-switch-flow-meter-flowmeter) --- *Product available on Desertcart New Zealand* *Store origin: NZ* *Last updated: 2026-04-25*
