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. Why is there no flow data when liquid passes through the flow meter? We will check in three steps: 1.

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. 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.

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.

Review: Accurate - Larger than expected but it works great Review: A critical part of an automotive coolant system - Used in automotive coolant circuit. This is a substantially sized component being 3" high X 5.5 in long without hose barbs for attaching 1.5in coolant hoses. Keep in mind the flow guage with hose barbs is about 10 in long. Not a small part to fit into your hose layout but very nice quality overall. ## Features - Not waterproof: Dry Environment Only, suitable for sheltered locations. Keep away from rain, humidity, and condensation. Do not immerse. - Five Unit Options - Our 1.5 inch flow meter allows you to switch between GAL(US Gallons), QTS, PTS, L, and m³ units to suit your measurement needs, offering flexibility and convenience. Flow range: 10.5-74 GPM(40-280 LPM), working pressure: 6 Bar. - Clear LCD Display - Our digital fuel flow meter's easy-to-read screen shows real-time flow rates, accumulated totals, and instant flow data. Monitor and record liquid use effortlessly. Single count range: 99999; Total cumulative count range: 29999999. - Accurate Measurements - Our digital turbine flow meter ensures precise readings with ±1% high accuracy. Trust it to provide reliable data for liquids like water, diesel, gas oil, gasoline, kerosene, methanol, E15, and more. - Energy-Efficient - The digital water flow meter's display screen automatically turns off after 10 minutes of inactivity, conserving energy. It reactivates when liquid flows or with the press of any key. Enjoy a standby time of over 1 year. ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 3.8 out of 5 stars 16 Reviews | ## Images ![1.5 Inch NPT Digital Flow Meter, 10.5-74 GPM Inline Fuel Turbine Flowmeter with LCD Display for Water, Diesel, Gas Oil, Gasoline, and Other Liquids - Supports Gallon, QTS, PTS, L, m³ - Image 1](https://m.media-amazon.com/images/I/71-moSftx0L.jpg) ![1.5 Inch NPT Digital Flow Meter, 10.5-74 GPM Inline Fuel Turbine Flowmeter with LCD Display for Water, Diesel, Gas Oil, Gasoline, and Other Liquids - Supports Gallon, QTS, PTS, L, m³ - Image 2](https://m.media-amazon.com/images/I/81wZAWNm+KL.jpg) ![1.5 Inch NPT Digital Flow Meter, 10.5-74 GPM Inline Fuel Turbine Flowmeter with LCD Display for Water, Diesel, Gas Oil, Gasoline, and Other Liquids - Supports Gallon, QTS, PTS, L, m³ - Image 3](https://m.media-amazon.com/images/I/81a1aF8gbnL.jpg) ![1.5 Inch NPT Digital Flow Meter, 10.5-74 GPM Inline Fuel Turbine Flowmeter with LCD Display for Water, Diesel, Gas Oil, Gasoline, and Other Liquids - Supports Gallon, QTS, PTS, L, m³ - Image 4](https://m.media-amazon.com/images/I/81uqs+uJOjL.jpg) ![1.5 Inch NPT Digital Flow Meter, 10.5-74 GPM Inline Fuel Turbine Flowmeter with LCD Display for Water, Diesel, Gas Oil, Gasoline, and Other Liquids - Supports Gallon, QTS, PTS, L, m³ - Image 5](https://m.media-amazon.com/images/I/8107GqrMJVL.jpg) ## Questions & Answers **Q: Why is there no flow data when liquid passes through the flow meter?** A: We will check in three steps: 1.

I wanted to see how accurate it would be so I filled up a 5 gallon pail first when I was done filling up the meter Reas 11 gallons. It was 5 gallons. ## Frequently Bought Together - GRYVOZE 1.5 Inch NPT Digital Flow Meter, 10.5-74 GPM Inline Fuel Turbine Flowmeter with LCD Display for Water, Diesel, Gas Oil, Gasoline, and Other Liquids - Supports Gallon, QTS, PTS, L, m³ - GRYVOZE 1 Inch Digital Turbine Fuel Flow Meter, 2.6-26 GPM Inline NPT Thread Flowmeter with 3/4 in Adapters for Water, Diesel, Gas Oil, Gasoline, and Other Liquids - Supports Gallon, QTS, PTS, L, m³ - Apeixoto 3/4 Inch Fuel Swivel, Fuel Hose Swivel with 3/4'' NPT Connector Fuel Plane Swivel with 360 Roating Connector --- ## 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.pt/products/612453193-1-5-inch-npt-digital-flow-meter-10-5-74](https://www.desertcart.pt/products/612453193-1-5-inch-npt-digital-flow-meter-10-5-74) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-06-07*
