OGFM Oval Gear Flow Meter

When Viscosity Changes – Your Meter Must Not Care

Most flowmeters are built for water-thin liquids. Change to asphalt, adhesive, or crude oil, and accuracy drifts.

The OGFM doesn't care.

It's a positive displacement oval gear meter. Every rotation traps a fixed volume. Every pulse counts. No estimation. No drift from viscosity changes. No surprises.

Built for the Fluids That Matter

Your Challenge	OGFM Answer
High-viscosity liquids	Positive displacement – viscosity has zero effect on accuracy
Asphalt and bitumen	Handles thick, sticky media – no clogging, no drift
Methanol and solvents	SS304/SS316 options – compatible with aggressive chemicals
Adhesives and resins	Precise volumetric measurement – consistent dosing
Crude oil and heavy oil	Wide flow range – 40~120,000 L/H – covers small to large transfer
Wide pipe sizes	DN10 ~ DN200 – from small lines to large pipelines
High pressure	1.6 MPa working pressure – handles pressurized transfer lines
Multiple connection types	Flange, clamp, thread – matches your existing piping
Multiple material options	Cast iron, cast steel, SS304, SS316 – choose the right material for your fluid
Multiple output options	4~20mA, pulse – connects to any control system
Display options	LCD or mechanical digital – local readout available

Why Oval Gear – Not Turbine or Electromagnetic

Meter Type	Limitation	OGFM Advantage
Turbine	Cannot handle high viscosity, wears quickly	Positive displacement – viscosity-independent, durable
Electromagnetic	Requires conductive liquids – oils and adhesives are not conductive	Works with non-conductive fluids
Ultrasonic	Struggles with viscous, opaque fluids	Direct volumetric measurement – no signal issues
Coriolis	High cost, size limitations	Lower cost, larger sizes available

OEM Equipment	Dosing skids, transfer systems, blending	Compact, customizable, multiple outputs

One Question

Would you rather guess your viscous liquid flow – or measure it?

Guessing leads to batch errors. Guessing leads to billing disputes. Guessing leads to process instability.

Measurement leads to precision. Measurement leads to profit. Measurement leads to confidence.

The OGFM gives you the number you can trust.
