Quick Answer
Vegetable Oil Flow Meter DN150 Processing Line Bulk Intake Controls
For vegetable oil bulk intake on a DN150 process line, Silver Automation Instruments supplies oval gear flow meters in DN150 with PT100 temperature compensation for custody transfer and batch control. The meter outputs 4-20 mA HART, handles 200 to 8000 L/min, and holds up to repeated CIP at 85°C. We size the meter based on your oil type, line pressure, and PLC connection. Send us your oil viscosity at working temperature, pipe schedule, and flow range for a same-day quote.
Vegetable oil measurement on a DN150 intake pipe causes headaches many engineers ignore at first. A dairy spreads plant in Indonesia ran a turbine meter on palm olein and lost 2% of every truck unload for three years. The issue was not the meter brand. The oil viscosity dropped from 55 cP at 30°C to 12 cP at 55°C during steam tracing. Turbine meters drift badly when viscosity shifts more than 5 cP. Oval gear meters do not drift under viscosity change. That is why most food plants in Southeast Asia now use oval gear flow meters from Silver Instruments for bulk oil intake.
In practice, a DN150 line needs a large chamber oval gear meter, often with PEEK gears and 316L housing. The Silver Instruments SOG-L150 series covers DN150 flange connections to EN 1092-1 PN16 or ANSI 150 lb. The meter sits right after the strainer on the intake manifold. Strainer mesh must be 40 mesh or finer for rapeseed oil and sunflower oil. For crude palm oil with fines, use 20 mesh and a Yokogawa-style magnetic filter before the meter. If you skip this, solid impurities lock the gears and the meter will trip the batching PLC with a flow alarm.
Temperature compensation matters as much as the meter type. A batch of soybean oil at 15°C has 2.3% more mass per liter than at 45°C. If you run intake by volume only, you under-receive cold oil and over-receive warm oil. Silver Instruments builds a PT100 into the meter body and sends temperature via 4-20 mA to the batch controller. The SOG-L150-PT outputs compensated volume in liters at 15°C using the API table for vegetable oils. Custody transfer systems in Vietnam and Colombia now demand this compensation because their traders audit the intake data monthly.
Here is the exact spec we quote most often for a DN150 intake skid. Flow range 300 to 6000 L/min for soybean oil at 30°C, viscosity 32 cP. Meter body CF8M stainless steel, gears PEEK, bearings tungsten carbide. Accuracy ±0.2% of reading above 10:1 turndown, repeatability ±0.03%. Flanges 6 inch ANSI 150 RF. Outputs dual pulse, 4-20 mA HART, and RS485 Modbus RTU. ATEX Zone 1 II 2G Ex ia IIC T4 if the intake area handles hexane-extracted crude oil. We ship three weeks after order, sea freight to your port, typically Ho Chi Minh, Jeddah, or Lagos.
Most engineers skip the air eliminator because DN150 lines have low air entrainment. But if your intake pump loses prime between truck unloads, air pockets hit the meter hard. We have seen this on customer sites many times. A built-in air eliminator on the meter inlet vents air automatically and stops measurement when gas fraction exceeds 3%.

Silver Instruments also supplies the batch controller for the intake. Model SIL-9800-R2 handles two-stage valve control, recipe storage for five oil types, and Ethernet/IP for Rockwell PLCs. One food oil refinery in Thailand uses this controller to intake crude palm oil, soybean oil, and sunflower oil through the same DN150 manifold. The operator selects the recipe, hits start, and the controller ramps the intake valve to 80% open, then throttles to 10% at trip point, and shuts off at setpoint. Overfill errors dropped to zero after the upgrade.
For high-viscosity oils like castor oil or hydrogenated palm stearin above 500 cP at 60°C, oval gear meters still work but need increased clearances. Silver Instruments can supply the SOG-L150-HV with enlarged gear clearances and steam jacket up to 150°C. The meter maintains ±0.5% accuracy up to 1000 cP. If the oil solidifies in the pipe, the meter must be drained and flushed with hot water immediately after each batch. We include a drain plug and quick-release end cover for this reason.
What about Coriolis meters for DN150 vegetable oil intake? They work beautifully but cost 3x to 5x more. A Coriolis meter does mass flow directly, needs no temperature compensation, and handles entrained air up to 10%. For a 6-inch line, the meter price starts at USD 22,000 FOB. Oval gear meter price starts at USD 6,800 FOB. If your budget allows and you need custody transfer to 0.1% mass accuracy, Coriolis is the better choice. Otherwise oval gear does the job for most bulk intake applications.
We recommend a factory acceptance test with your oil at your working temperature. Silver Instruments has a test loop in Perth with a 5000 L tank and heating jacket. You ship 20 liters of your oil, we run the test and send video, calibration certificate traceable to NATA, and repeatability data. This gives your plant engineer confidence before the meter lands on site.
FAQ
Can I use a vortex flow meter for vegetable oil on DN150
No. Vortex meters drop out below Reynolds number 20,000, which happens with viscous oil at low flow. Oval gear is correct for this service.
Does the meter need recalibration every year
If you measure edible oil for custody transfer, annual verification against a master meter or weigh scale is industry practice. Silver Instruments supplies a portable calibration trolley for DN150 meters.
Can the oval gear meter handle CIP chemicals
PEEK gears and FKM seals are compatible with 2% caustic soda at 85°C and nitric acid 0.5% at 70°C. EP is recommended for acid CIP above 1% concentration.
What is the pressure drop at 6000 L/min
For soybean oil 32 cP, pressure drop is 0.6 bar across the meter. Ensure intake pump head can handle this plus pipe loss.
How do I order a DN150 vegetable oil flow meter
Send us your oil type, normal and max flow rate, working temperature, pipe material, hazardous area classification, and PLC protocol. Quote will include meter, PT100, batch controller, and filter.
