Quick Answer: For jet fuel distribution headers using DN200 pipe, a Coriolis mass flow meter is the most practical instrument. It gives direct mass flow and density, handles 180 000 kg/h without wear parts, and demands almost zero straight pipe run. Silver Instruments supplies ATEX and IECEx certified Coriolis meters with 4-20 mA HART, Modbus, and a proven track record in Southeast Asian fuel depots.
Jet Fuel Flow Meter DN200: Handling Main Pipeline Distribution Scales
In a busy airport fuel depot or bulk terminal, Jet A-1 moves through a 200 mm main header at flow rates from 80 m³/h to over 500 m³/h. Pipeline pressure usually sits between 10 bar and 16 bar, and the fluid temperature hovers around 25 °C. The meter on this DN200 line does a tough job. It must deliver custody transfer accuracy, survive long idle periods, and give operators confidence when they push 150 000 kg of fuel into a hydrant system in 30 minutes. Old installations used turbine meters. Those needed frequent bearing checks because jet fuel acts as a low lubricity fluid. Positive displacement meters added pressure drops above 0.8 bar and wore out their internals too fast. In practice, many depot managers in Vietnam, the Philippines, and the Middle East now choose a Coriolis mass flow meter sized for DN200. Silver Instruments installed two SIL-CM200 meters at a terminal near Da Nang in 2024 that batch-load 16 hydrant carts every day. The meters measure mass flow, density, and temperature with a single instrument, eliminating the need for separate density meters.
Why Coriolis Wins Over Vortex and Ultrasonic on Jet Fuel
Jet fuel has a resistivity that kills magmeter operation. That narrows the choice to Coriolis, vortex, and ultrasonic. Vortex meters for DN200 work but need 15D to 25D upstream straight run after an elbow or tee. In a compact fuel manifold, that space is simply not available. Ultrasonic clamp-on meters struggle with signal loss on old pipe and still need clean calibration. A Coriolis flow meter like our SIL-CM200 needs zero upstream straight pipe. It just sits between a set of isolation valves and goes to work. Because the Coriolis principle measures mass directly, you do not need density correction tables for Jet A-1 at 15 °C versus 25 °C. The meter outputs live density around 775 kg/m³ to 800 kg/m³. Any drop caused by air entrainment or a surge of low grade fuel triggers an immediate alarm in the SCADA.
What a DN200 Coriolis Meter Looks Like on Site
A SIL-CM200 meter for jet fuel has 316L stainless steel wetted parts and ANSI B16.5 Class 150 raised face flanges. Nominal mass flow capacity is 200 000 kg/h at a reasonable pressure loss of 0.4 bar. Mass accuracy sits at ±0.10% of rate for flows above 20 % of full scale. Density accuracy reaches ±0.5 kg/m³. The transmitter mounts directly on the sensor or remotely via a 4-wire cable. It ships from our factory with an Ex db ia IIB T4 Gb certification plate, valid for Zone 1 areas. Output options include one 4-20 mA HART for mass flow, a passive pulse output for a totalizer, and Modbus RTU RS485 for density, temperature, and diagnostic registers
Installation and Calibration Realities
A DN200 Coriolis meter weighs roughly 400 kg. You need a pipe support on each side and a lifting plan for the final connection. The process connection reads jet fuel at an average density of 785 kg/m³, so we set the factory calibration with a jet fuel simulant that matches viscosity of 1.3 cP at 25 °C. Every meter gets a 5-point wet calibration. The certificate is traceable to an ILAC-accredited laboratory, which settles any customs or billing dispute at the receiving terminal. On site, commissioning takes half a day. Most engineers skip the zero check and go straight to a tightness test, then batch verification against a weighbridge. The SIL-CM200 has passed batch checks with deviation under 0.07% in a recent commissioning at a Manila airport fuel depot.
FAQ
Can the SIL-CM200 handle peak flow spikes above 200 000 kg/h?
The meter tolerates short overloads up to 120% of nominal flow. During a 15-minute peak surge in a hydrant pit, you can push 220 000 kg/h without damage. We size the meter so your normal peak stays at 80% of the nominal rate to keep pressure loss low.
Does the Coriolis meter drift over time with jet fuel?
No. The tube oscillates at its natural frequency. There are no moving parts to wear, and the drive gain diagnostics tell you if coating or corrosion ever starts. We recommend a field verification every 24 months with a reference prover if your ISO 9001 procedures require it, but actual drift is almost never seen.
Is the meter certified for ATEX Zone 1 in fuel storage areas?
Yes. Our SIL-CM200 holds both ATEX and IECEx Ex db ia IIB T4 Gb. The sensor and junction box are rated for direct installation in Zone 1 at loading racks and tank dikes. Use suitably rated cable glands and the barrier is built into the transmitter.
Can you detect water or air in the jet fuel with this meter?
Yes. Live density serves as a quality gate. Pure Jet A-1 at 20 °C measures about 785 kg/m³. If density jumps above 800 kg/m³, water contamination is likely. If density drops erratically, air is entering the line. The meter can send alarms on both density limits over Modbus to the control room.
What is the delivery time and price for a DN200 Coriolis meter?
Typical lead time is 8 to 10 weeks for a SIL-CM200 with ATEX certification. Send us your operating pressure in bar, full scale flow in kg/h, flange standard, and hazardous area zone. We will return a formal quotation with shipping weight and pricing. Our team supports installations across Southeast Asia, the Middle East, and Latin America.
