Featuring a sharp LCD display with multiple unit options, EMI shielding for stable readings near motors, and a durable aluminum alloy casing, it’s engineered for professional-grade monitoring of water, diesel, gasoline, and more. Its power-saving auto-off and non-volatile memory ensure reliable, hassle-free operation in demanding environments. ## Description Introducing our 3 in digital turbine flow meter - a reliable and efficient solution for accurate liquid measurements. Whether you need to measure water, diesel, gas oil, gasoline, kerosene, methanol, E15, or other low-corrosive, non-viscous liquids, this industrial flow meter has got you covered. The liquid flow meter is designed with power-saving functionality, automatically turning off the display after 2 minutes of inactivity. When liquid flows through, the digital flow meter will power on automatically, or you can easily turn it on with a simple keystroke. Additionally, its non-volatile memory ensures that your settings and data are retained even when the power is off. The default unit of measurement for this digital fuel flow meter is liters. If the unit is not in liters, please refer to the user manual to change it to the desired unit. It can be switched to QTS, PTS, L, GAL, m³. We take pride in delivering a calibrated product, saving you the hassle of manual calibration. Our factory-calibrated flowmeters provide accurate readings right out of the box, ensuring reliable and precise measurements for your needs. When you notice a decrease in the accuracy of the flowmeter, it is necessary to calibrate the flow meter to ensure precision. To maintain measurement accuracy, it's crucial to ensure a steady and stable pressure during use. Avoid arbitrary adjustments to the outflow position, as it may impact the precision and accuracy of the measurements. Keep in mind that the turbine meter is not suitable for direct, close-range connection to pumps, as it may cause interference and lead to data instability. For accurate readings, make sure the liquid flow velocity falls within the required range: 21-264 GPM(80-1000 LPM). Furthermore, if you intend to measure high-viscosity liquids such as lubricating oil or engine oil, we recommend choosing a gear flow meter instead of a turbine flowmeter! Review: It can't get wet and it's made for water flow - This has been sent back already.. It's a piece of garbage Review: NOT NPT - As noted by others BEWARE not NPT threads as advertised the threads are BSP. The adaptors each cost more than the flow meter if you need NPT. ## 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(Gallons), QTS, PTS, L, and m³ units to meet your specific measurement needs, offering flexibility and convenience.

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. ## Customer Reviews ### ⭐ It can't get wet and it's made for water flow *by B***S on 16 May 2026* This has been sent back already..
