# Gasoline Flow Meter 1 Inch: Specifications, Selection, and Buying Guide
## Quick Answer
A gasoline flow meter 1 inch size typically handles flow rates from 10 to 150 L/min for most fuel dispensing and transfer applications. For accurate gasoline measurement, oval gear flow meters with 4-20 mA output are the most common choice. Send us your pressure (bar), temperature (°C), pipe size (DN), and expected flow range to get a specific model recommendation.

## Project Context
I work with Silver Automation Instruments. We supply industrial flow meters and process instruments to oil and gas terminals, fuel depots, and chemical plants across Southeast Asia, Latin America, the Middle East, and Africa. Our customers include diesel distributors in Indonesia, fuel storage operators in Nigeria, and marine fuel suppliers in Australia.
Our product range includes Coriolis mass flow meters, electromagnetic flow meters, ultrasonic flow meters, vortex flow meters, oval gear flow meters, thermal mass flow meters, pressure transmitters, and paperless recorders.

## Why 1 Inch Gasoline Flow Meters Matter
Gasoline flow measurement is different from water or chemical dosing. Gasoline has low viscosity around 0.5 to 0.6 cP at 20°C. It also has volatile vapors that can affect measurement accuracy. The pipe size opens a lot of possibilities.
Most gasoline transfer operations use pipes between DN25 and DN50. The 1 inch DN25 size fits right in the middle. It works for truck loading arms, fuel dispensers, and small refinery transfer lines. We have seen this on customer sites many times.
A paint manufacturer in Southeast Asia called us last year. They needed to measure gasoline for mixing solvents.
Their pipe was exactly 1 inch. They tried a turbine meter first. The gasoline vapors caused cavitation. We replaced it with an oval gear meter. Problem solved.

## Technical Specifications for 1 Inch Gasoline Flow Meters
### Oval Gear Flow Meter (Most Recommended)
| Parameter | Specification |
|-----------|--------------|
| Pipe Size | 1 inch DN25 |
| Flow Range | 5 to 150 L/min |
| Accuracy | ±0.5% of reading |
| Viscosity Range | 0.5 to 5000 cP |
| Temperature | -40°C to +150°C |
| Pressure Rating | 40 bar standard |
| Output Options | 4-20 mA HART, pulse, RS485 |
| Material | Cast iron or stainless steel |
| Connection | BSP threaded or flanged |
The oval gear meter has two rotating gears. Gasoline pushes the gears. Each rotation equals a fixed volume. This mechanical principle avoids issues with gasoline vapors.
### Coriolis Mass Flow Meter
A Coriolis meter measures mass flow directly. It does not care about gasoline density changes with temperature. Temperature compensation is built in. The accuracy stays at ±0.1% to ±0.2%.
For 1 inch size, typical flow range is 0 to 600 kg/h. Maximum pressure is 100 bar. Output is 4-20 mA HART with Modbus optional.
The downside is cost. A Coriolis meter costs 3 to 5 times more than an oval gear meter. We recommend it only when custody transfer accuracy is required.
### Turbine Flow Meter
A turbine meter works for clean gasoline. The spinning rotor generates a frequency proportional to flow rate. Accuracy is ±1% of reading. Operating range is 10 to 200 L/min for 1 inch size.
Last year a customer in Vietnam asked us for a turbine meter on their gasoline blending line. The pipeline had small particulate from storage tanks. The turbine rotor stuck after two months. We s『SILVER Official Website SERVICE』
