In Line Fuel Flow Meter: Real-Time Gasoline and Diesel Consumption Logs
Quick Answer: Inline fuel flow meters from Silver Automation Instruments give you direct access to real-time gasoline or diesel consumption data. Our oval gear and Coriolis meters send 4-20 mA, pulse, or RS485 signals to your PLC or paperless recorder. This setup helps you track fuel costs, detect engine overconsumption, and prevent diesel theft in Southeast Asia, Australia, and the Middle East.
Why Direct Fuel Measurement Matters
A diesel generator in a remote mine in Western Australia burns 40 liters per hour. If the operator does not log this in real time, one leaking injector can waste 200 liters in a single shift. In practice, most engineers skip the dipstick method after they install an inline meter. We have seen this on customer sites many times. Because fuel is a major operating cost, small measurement gaps add up fast. But a proper flow meter gives you a totalized log that cannot be faked.
Which Meter Fits Your Fuel Line
Silver Automation Instruments supplies two main inline technologies for gasoline and diesel logs. The OGF series oval gear flow meter works well for most engine, generator, and burner applications. It handles flow ranges from 1 L/h up to 1000 L/h, pipe sizes DN4, DN6, DN10, DN15, DN20, and DN25, and pressures up to 40 bar. Temperature limits are -20 °C to 80 °C. The meter body is anodized aluminum, and the gears are PPS or PTFE. Standard accuracy is ±0.5% of reading with repeatability of ±0.05%. Output options include a 4-20 mA loop, an open collector pulse, or RS485 Modbus. This data feeds directly into the Silver VX series paperless recorder, creating a tamper-proof consumption log.
For custody transfer or blending where mass matters more than volume, our miniature Coriolis mass flow meter measures gasoline and diesel with ±0.2% accuracy. One device gives you mass flow, density, and temperature. It is a good fit for fuel loading skids and chemical burner lines. Because the Coriolis meter has no moving parts, there is almost zero drift over time. So you get the same log quality after five years as on day one.
A Real-World Example
Last year, a customer in Vietnam who manages a fleet of 30 fishing vessels asked us to solve a diesel waste problem. We supplied 60 oval gear meters with pulse outputs wired to their onboard PLCs. Real-time consumption per trip showed exactly which engines were overburning. The data helped them cut fuel waste by 12% in the first quarter. In another case, a chemical plant in Saudi Arabia installed our Coriolis meters on diesel burners and ran Modbus cables straight into their central SCADA. The maintenance team now schedules burner cleaning based on actual fuel flow logs, not calendar guesses.
Installation S_600x400.jpg)
Here is the thing about inline fuel flow meters: they love clean fuel. Fit a 60-micron Y-type strainer right upstream. Diesel and gasoline often carry small rust particles from storage tanks. Without a strainer, the oval gears can jam. Install the meter at a low point in the line to avoid air pockets. Air makes the meter read high and ruins the log accuracy. For gasoline, check material compatibility. Our standard OGF aluminum body with PTFE gears handles most gasoline blends, but if your fuel has ethanol or aggressive additives, we can switch to stainless steel and Viton seals. Most engineers skip this part, but it saves you hours of troubleshooting later.
Logging Data Without Extra Effort
Silver VX paperless recorders grab the 4-20 mA or Modbus signal directly. Each channel gets a tag: Generator A, Main Engine Port, Burner Line 3. The recorder stores flow rate and daily totals on an SD card. If flow deviates more than 10% from the baseline, it triggers a relay alarm. Many customers in the Middle East use this to catch diesel theft from shared tanks overnight. Because the log is digital, you can export it as a CSV file and email it to your fleet manager.

FAQ
Can an inline flow meter measure both gasoline and diesel?
Yes. Our oval gear meter handles both fluids because the internal gears are compatible with gasoline and diesel. Just select the right seal material, Viton or PTFE. Do not use the same meter for gasoline if it previously measured heavy fuel oil without a deep cleaning.
What accuracy can I expect for fuel consumption logs?
Oval gear meters deliver ±0.5% of reading, Coriolis meters ±0.2%. The totalized pulse output ensures no data drift. We match the K-factor to your flow range at our Nanjing factory before shipping.
How do I connect the meter to my PLC or data logger?
Use the pulse output or 4-20 mA signal. We provide wiring diagrams. Most customers connect to Siemens, Allen Bradley, or Mitsubishi PLCs. The RS485 Modbus option lets you read multiple flow meters on one bus directly into a Silver recorder or your SCADA.
What pipe sizes do you offer for diesel generators?
We stock DN4, DN6, DN10, DN15, DN20, and DN25 as standard. Larger sizes up to DN50 are available on order. For a typical 500 kVA generator, DN15 or DN20 is the common choice.
Do you have ATEX or explosion-proof certificates for fuel measurement?
Yes. Our oval gear meters are available with ATEX Zone 2 or Zone 1 certification. The Coriolis meter can be supplied with Ex d or Ex ia approvals. Tell us your zone classification and gas group when you send the inquiry.
