Why is there no flow data when liquid passes through the flow meter?

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.

If the flow meter runs out of power, do I need to remove it from the pipeline?

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.

How long can I maintain the flowmeter after receiving a low battery warning?

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.

Why is my digital display not working or displaying incorrectly?

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.

Why does my newly purchased flow meter have errors when measuring water?

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.

Used it with water to gauge tanks. Accuracy is good enough out of the box, it was within 3 gallons on a 1000 gallon tank so I didn't even bother to calibrate it for accuracy. Ran it consistently at 10-12 gpm.

I recently acquired the Digital Fuel Flow Meter for my workshop, and I couldn't be more pleased with its performance. This device has truly simplified the way I monitor and record liquid usage. The clear LCD display is a standout feature, providing real-time flow rates, accumulated totals, and instant flow data at a glance. It's incredibly user-friendly, allowing me to switch between five different unit options effortlessly to suit my measurement needs. Accuracy is key when it comes to measuring fuel, and this digital turbine flow meter doesn't disappoint. With a high accuracy of ±1%, I can trust it to deliver precise readings consistently. Plus, the energy-efficient design is a bonus, with the display screen automatically turning off after 2 minutes of inactivity to conserve power. Although this can sometimes be annoying and I wish there was a way to program it such that you can decide how many minutes before it turns off. Durability is another highlight of this product. Its rugged design, featuring an aluminum alloy casing and stainless steel turbine, ensures it can withstand various environments and provide long-lasting performance. Overall, the Digital Fuel Flow Meter has exceeded my expectations. It's a reliable tool that simplifies fuel monitoring while offering accuracy, efficiency, and durability. Whether you're a professional in the industry or a hobbyist like myself, I highly recommend adding this device to your toolkit. It's definitely worth the investment.
