Cooking Oil Flow Meter 100 L/h Small Batch Processing Manuals
Quick Answer
For 100 L/h cooking oil dosing in small batch processing, an oval gear flow meter with DN10 or DN15 connections delivers repeatable results. Silver Automation Instruments supplies the OGF series with food grade seals, 4-20 mA HART output, and local totalizer. Manuals, wiring diagrams, and CAD step files come with every shipment. Send pipe size, oil type, and batch volume to get the data sheet matched to your CIP skid or filling line.
Why Oval Gear Meters Handle 100 L/h Cooking Oil Better Than Other Types
Small batch oil batching below 200 L/h is unforgiving. Turbine meters lose accuracy at low flow and high viscosity. Coriolis meters are precise, but the cost per point often kills the project for 100 L/h sunflower oil or palm olein lines. Oval gear positive displacement meters skip those problems. Two oval rotors sweep a known volume per pocket. Flow rate does not affect the swept volume inside the chamber. Even at 80 L/h, the pulse output is steady. Because the meter counts discrete pockets of oil, not velocity, viscosity swings from 20 cP to 300 cP stay inside the error band.
Key Specifications for 100 L/h Batch Runs
Most engineers we talk to in Southeast Asia and the Middle East need a meter that can handle 60 L/h to 150 L/h without losing pulses. Our OGF-06 model covers 30 L/h to 300 L/h on thin oils. For palm oil or coconut oil at 40°C to 60°C, we often specify OGF-10 with a 5:1 turndown. Standard body is 316L stainless steel. Rotors come in PPS or aluminum depending on CIP chemical exposure. Process connections are sanitary tri-clamp 1 inch or BSPP threaded DN15. Repeatability stays within ±0.1%. Accuracy across the full range is ±0.5% of reading. Output options include two wire 4-20 mA with HART 7, NPN/PNP pulse, and Modbus RTU. Supply voltage is 8 to 30 VDC. The local display shows rate in kg/h or L/h and batch total. We set the display to your units before shipping.
What the Manuals Cover and How to Get Them
Every Silver oval gear flow meter arrives with a printed manual and a USB stick. The PDF includes a dimensional drawing with envelope length, clearance for rotor removal, and recommended straight pipe runs. Wiring tables for terminal block, pin assignments for M12 connectors, and grounding diagrams are inside the commissioning section. K-factor tables list pulses per liter for 5 viscosity ranges. One section covers CIP safety: maximum temperature 150°C, max caustic concentration 2% at 80°C, and rotor removal steps for manual cleaning. Because small batch lines often switch between soybean oil, rice bran oil, and fryer shortening, the manual explains how to flush and recalibrate onsite. For users who lost the original copies, we email the zip folder within one working day. Ask for “OGF cooking oil manual 100 LPH” in the request form. Our support team includes the certificate of calibration, material traceability 3.1 per EN 10204, and the pressure test report in the same package.
Real Installations We Have Seen
A snack food factory in Vietnam doses 95 L/h of palm olein into a fryer line. They use OGF-10 with tri-clamp connections and a PT100 integrated into the meter body for density compensation. The batch relay triggers a pneumatic valve at exactly 18.5 liters. Their production manager told us pulse jitter at low flow disappeared after switching from a turbine meter to oval gear.

Common Pitfalls and How to Avoid Them
Air pockets are the number one enemy. Even a 2 mL bubble distorts the batch total. Install a simple air eliminator right before the meter inlet. In practice, put the meter at the lowest point of the line so gas cannot collect in the measuring chamber. Second, do not throttle the downstream valve to control flow if you use a positive displacement pump. That creates back pressure spikes and damages rotors over time. Use a VFD on the pump instead. Third, let the meter stay filled with oil during idle periods. Dry starts accelerate wear on PEEK bearings. Last, check the K-factor after you change oil grade. A shift from soybean oil to palm stearin at 50°C changes viscosity from 28 cP to 38 cP, and the K-factor may drift by 0.2%. Most customers perform a quick bucket test once a month and update the digital K-factor via the keypad.

FAQ
Can the meter handle 100 L/h intermittent batching with daily CIP?
Yes. The OGF series tolerates caustic wash at 80°C if you remove rotors or specify PTFE encapsulated rotors. We provide a detailed CIP procedure in the maintenance chapter.
What is the lowest measurable flow on a DN15 oval gear meter for viscous oil?
With 300 cP oil, the OGF-10 meter reads down to 25 L/h reliably. Below that, pulse spacing gets wide and batch timing becomes a challenge. Choose a smaller OGF-06 for 10 L/h to 60 L/h.
Do I need straight pipe before and after the meter?
No. Oval gear meters do not need flow conditioning. You can mount the meter right after an elbow or a strainer. A Y-type strainer 300 microns before the inlet is recommended to catch food particles.
Is the flow meter compatible with 24 VDC plant power?
Yes. The electronics accept 8 to 30 VDC. For 4-20 mA HART output, loop resistance should stay below 500 Ohm at 24 VDC. We include loop wiring examples in the manual appendix.
How do I download the 100 L/h cooking oil flow meter manual?
Visit the Silver Automation Instruments contact page on flow-meter.com.au. Write “OGF cooking oil manual 100 LPH” in the message field along with your company name. One of our application engineers sends the zip folder with the full manual, CAD files, and the calibration certificate the same day.
