Cooking Oil Flow Meter DN200: Bulk Delivery and Legal-for-Trade Compliance
Quick Answer: For DN200 cooking oil bulk delivery, you need a flow meter with legal-for-trade certification such as OIML R117 or MID. Silver Automation Instruments supplies oval gear and Coriolis meters that meet these standards. Send us your oil type, pipe size (DN), flow range, and temperature, and we will recommend a certified meter for your tanker loading station.
Why a Certified Meter Matters for Edible Oil Trade
In Australia, Indonesia, and the Gulf, edible oil distributors and refiners face strict measurement regulations. A flow meter without pattern approval cannot be used to print delivery tickets or issue invoices. We have seen a palm oil trader in Surabaya lose a shipment because their DN200 turbine meter had no legal-for-trade seal. Here is the thing: customs, port authorities, and buyers now demand OIML R117 or MID marking before they accept a bulk transfer. Oval gear and Coriolis meters from Silver Instruments carry factory-supplied certificates and can be verified on site by local weights and measures officers. This keeps your loading bay compliant and your payment cycle short.
Oval Gear Flow Meter DN200 for High-Viscosity Cooking Oil
Most engineers skip this part, but for oils like palm, soybean, coconut, or canola, an oval gear meter is often the safest choice. The meter handles viscosities from 10 cP to over 100,000 cP without losing accuracy. Our DN200 model typically delivers a pulse output of 0.1 L per pulse, direct to your batch controller or PLC. A recent installation in Vietnam uses this meter to fill ISO tank containers at 850 L/min with coconut oil at 45 °C. The unit runs a 4-20 mA HART transmitter, a PT100 for temperature compensation, and a local mechanical totalizer. Accuracy stays within plus minus 0.2% across two shifts daily. Bearings are tungsten carbide. Housing is 316L stainless steel. We also provide PN40 flanges, a strainer, and an air eliminator for complete custody transfer skids.
Coriolis Mass Flow Meter DN200 for Direct Weight Measurement
In practice, many bulk buyers prefer to pay by mass, not volume. Cooking oil density shifts with temperature and grade. A Coriolis meter measures mass flow and density directly, so your invoice matches the actual weight loaded. Silver Instruments offers a DN200 Coriolis meter that reads up to 1,500 kg/min with plus minus 0.1% accuracy. The sensor has no moving parts and handles process temperatures up to 150 °C. Because it meets OIML R117, it is accepted for trade in over 30 countries, including Malaysia, the UAE, and New Zealand. A food oil exporter in Johor recently switched from weighbridge to
Installation Tips for DN200 Bulk Loading Stations
Start with a good flow profile. Oval gear meters are less sensitive, but we still recommend a straight run of 3D upstream and 2D downstream. Fit a Y-type strainer right before the meter to catch debris from tank bottoms. We always install a pulsation damper when the pump is positive displacement. For Coriolis meters, support the pipe properly so the meter body sees zero stress. Do not install the meter at the highest point where air can collect. Temperature sensor must be in good contact. Typical output setup: two pulse outputs to the batch controller, one 4-20 mA to the DCS, and a local display for the operator. In many sites across Thailand and the Philippines, operators pair our DN200 meters with a pneumatic shut-off valve and a two-stage closure to avoid overfilling.
FAQ: Cooking Oil Flow Meter DN200 Legal-for-Trade
What approvals do I need for edible oil custody transfer in Southeast Asia?
Most countries accept OIML R117 or MID. Local pattern approval may be required in Thailand and Indonesia. Silver Instruments supplies full documentation and supports your local verification.
Can an oval gear meter handle palm oil at 50 °C?
Yes. Palm oil runs around 30 to 50 cP at that temperature. Our oval gear meters measure from 1 cP to over 100,000 cP. The gears are hardened for long runs.
How do you prove meter accuracy during commissioning?
We use a prover tank or a master meter traceable to NIST. Our factory calibration certificate lists the error curve at three flow rates. On site, most customers run a 5-point check and seal the meter.
Do you offer ATEX or IECEx versions for oil loading?
Edible oil loading is usually non-hazardous. However, if your process involves hexane extraction, we can provide a certified ATEX Zone 1 meter with stainless steel housing and flameproof transmitter.
What spare parts should I stock for a DN200 oval gear meter?
Keep one set of gears, two shaft seals, and a bearing kit. The meter is easy to open. We ship spares from our Brisbane and Singapore hubs.
