Review: Does the Job - This digital flow meter does the job well. It’s really large at 3 inch piping. It is easy to use and has good instructions. Installation is quite easy if you use the right Teflon tape with what liquid you are using with it. Overall, I think it’s a good product.
Review: Weird thread size so it's worthless - I cannot find a fitting with the correct thread size. I would like to use this at work but I don't know why none of the cam lock 3 inch ntp fittings work. It's currently a paper weight.

## Features

- Digital LCD Display - The clear LCD screen of the 3 inch flow meter shows real-time flow rates, accumulated totals, and instantaneous flow. It makes monitoring and recording your liquid usage easy. Single count range: 99999; Total cumulative count range: 29999999.
- Accurate Measurements - Our digital turbine flow meter provides precise readings with a high accuracy of ±1%, ensuring reliable data for liquids like water, diesel, gas oil, gasoline, kerosene, methanol, E15, and more.
- EMI Shielding: Our 3" flow meter is equipped with advanced electromagnetic interference protection, allowing for installation in close proximity to pumps or motors without interference.
- Versatile Unit Options - Switch between GAL(US Gallons), QTS, PTS, L, and m³ units to meet your specific measurement needs, offering flexibility and convenience. Flow range: 21-264 GPM(80-1000 LPM), working pressure: 6 Bar.
- Energy-Saving - The display screen of the digital water flow meter will turn off after 10 minutes of inactivity. It automatically turns on when there is liquid flow and can also be activated by pressing any key. Standby time: over 1 year.
- Durable Build - Crafted with an aluminum alloy casing and stainless steel turbine, this digital fuel meter is designed to withstand various environments and provide long-lasting performance. Working temperature: -10°C~80°C(14-176°F).
- Waterproof Rating - IPX4, not IPX8. Do not immerse this flowmeter in water, oil, or other liquids. It is not designed for submersion. To extend the lifespan of the built-in electronic board, please avoid splashing water on the dial.

## Questions & Answers

**Q: Why is there no flow data when liquid passes through the flow meter?**
A: We will check in three steps: 1. Remove the flow meter from the pipeline. 2. Blow air at the turbine to check for blockage. 3. If it spins, check the display. If there’s data, the flow is too low; if not, the chip may be faulty and needs replacement.

**Q: If the flow meter runs out of power, do I need to remove it from the pipeline?**
A: No, you only need to unscrew the screws and remove the display panel to replace the battery inside. There's no need to remove the entire flow meter, and no data will be lost during the battery replacement process.

**Q: How long can I maintain the flowmeter after receiving a low battery warning?**
A: Under normal conditions, after the low battery warning appears, it is expected to last for about a week to a month. We recommend replacing the battery as soon as possible.

**Q: Why is my digital display not working or displaying incorrectly?**
A: Please check the auto-sleep function and try replacing the battery. If neither works, the flowmeter might have water damage, which can harm the PCB. If you need a waterproof model, we recommend purchasing our waterproof flowmeter.

**Q: Why does my newly purchased flow meter have errors when measuring water?**
A: Our flow meters are factory calibrated for fuel. If you are using it for tap water, you can manually adjust the coefficient to 1080. The adjustment steps can be found in our manual. For more precise data, you can perform a calibration.

### ⭐ Weird thread size so it's worthless

I cannot find a fitting with the correct thread size. I would like to use this at work but I don't know why none of the cam lock 3 inch ntp fittings work. It's currently a paper weight.

### ⭐⭐⭐ Flow meter uses British Pipe Thread, Not National Pipe Threads as advertised
*by T***S on April 24, 2025*

Flow meter does NOT use NPT (National Pipe Thread). Instead it uses a British thread which requires different fittings. The fitting cost more than the flow meter did.
