Fuel Transfer Flow Meter Selection: Explosion-Proof ATEX Certifications for Gasoline and Diesel
Quick Answer: For gasoline and diesel transfer, select an oval gear flow meter or a Coriolis mass flow meter with ATEX Zone 1 or Zone 2 certification. Match the meter body to fuel viscosity, pipe size from DN15 to DN100, and flow range. Silver Instruments supplies explosion-proof fuel transfer meters with 4-20 mA HART output, pulse output, and local totalizer display.
Why ATEX Certification Matters for Fuel Transfer
Gasoline vapor forms an explosive mixture in air. Diesel is less volatile but still dangerous in closed rooms and pits. A fuel transfer skid, loading rack, or tank farm needs a meter certified for the correct zone. ATEX certification covers the sensor, housing, cable glands, and local display. Without this certificate, site inspectors in Vietnam, Indonesia, Nigeria, or Saudi Arabia can reject the installation. In practice, most engineers skip this part until the inspector stops the commissioning.
Flow Meter Types for Gasoline and Diesel
Oval gear flow meters work well for diesel and low to medium gasoline flow. They are accurate to about 0.5 percent of reading. The body can be cast iron or stainless steel. The viscosity range covers 0.8 cP to 2000 cP, so diesel at 3 cP to 5 cP and gasoline at 0.6 cP are both possible with the right clearance. Coriolis mass flow meters measure mass directly in kg/h or t/h. They reach 0.1 to 0.2 percent accuracy and have no moving parts. They cost more but work well for custody transfer or low flow. We have seen this on customer sites many times.
Key Parameters to Specify
Pipe size matters first. DN15 to DN100 covers most fuel transfer skids. Flow range can be 0.5 L/min to 1000 L/min for small systems. Specify fuel type because gasoline has a viscosity around 0.6 cP and diesel around 3 cP to 5 cP. Pressure in bar and temperature in °C affect the seal and bearing choice. Output signal should be 4-20 mA HART plus pulse. Power supply is typically 24 V DC. Ingress protection should be IP65 or IP67. The ATEX marking can be Ex db IIB T4 Gb or Ex ib IIB T4 Gb. Request a local display with a resettable batch total.
Common Mistakes in Specifying Fuel Transfer Meters
Here is the thing. Many buyers order a water meter for diesel. The seals swell and the meter stops. A fuel terminal in the Philippines replaced three water meters before calling us. Another custome

FAQ on ATEX Fuel Transfer Flow Meters
What is the best flow meter for diesel transfer? An oval gear flow meter works well for diesel from DN15 to DN80. It gives reliable batch totals and costs less than Coriolis. For custody transfer or very low flow, select a Coriolis mass flow meter.
Does ATEX cover both gasoline vapors and diesel? ATEX certification depends on the gas group and temperature class. Gasoline vapor usually falls under IIA or IIB. Diesel vapor can be IIA. The installation zone defines the protection level. Always send the zone classification and fuel type.
What signal output should I request for fuel transfer? Request 4-20 mA HART plus pulse. Pulse works for batching. HART lets you read flow rate and total from the control room. A local display on the meter helps operators.
Can one meter handle gasoline and diesel? Yes. Many oval gear and Coriolis meters handle both fuels. Check the viscosity range and wetted materials. Gasoline has lower viscosity around 0.6 cP. Diesel is around 3 cP to 5 cP. The meter should cover both without losing accuracy.
