G1.0SS Micro Oval Gear Flow Meter-For Mercaptan Injection Systems and High-Precision Chemical Dosing
When Precision Is Not Optional
Mercaptan injection is one of the most demanding applications in the gas and petrochemical industry.
Too little – the odorant threshold isn't met. Safety risk.
Too much – wasted chemical, environmental concerns, regulatory issues.
The G1.0SS was built for this exact challenge.
It's a positive displacement oval gear meter. Every rotation traps a fixed volume. Every pulse counts. No estimation. No drift. No excuses.
Built for the Tough Jobs
| Your Challenge | G1.0SS Answer |
|---|---|
| Ultra-low flow | 0.4 L/H minimum – precise control even at tiny injection rates |
| High pressure | 32 bar rating – handles pump pulsation and injection pressure |
| Corrosive resistance | SS316 gears and SS housing – compatible with mercaptan and additives |
| Viscosity changes | Positive displacement – accuracy unaffected by temperature or viscosity shifts |
| Harsh environments | -40~80°C operating range – works in winter cold and summer heat |
| System integration | 4~26 VDC wide power – direct to your PLC or dosing controller |
| Noise concerns | Low noise emission – smooth gear operation, no high-frequency whine |
Why Mercaptan Injection Demands Oval Gear Technology
Mercaptan is a difficult fluid. It's volatile. It's corrosive. It demands precise dosing at very low flow rates.
Turbine meters? They can't handle the low flow or the viscosity changes.
Electromagnetic meters? They require conductive liquids – mercaptan is not one.
Ultrasonic meters? They struggle with bubbles and low-flow resolution.
The G1.0SS oval gear meter? It traps and counts. Every milliliter. Every injection. Every time.

What This Means for Your System
Mercaptan Injection Skids
Precise odorant dosing for natural gas pipelines. Every injection is measured, logged, and verifiable.
Chemical Dosing Systems
Accurate additive injection where flow rates are low and accuracy requirements are high.
Petrochemical Processing
Heavy oil, resin, PVA – high-viscosity media that other meters simply cannot handle.
High-Pressure Injection
32 bar rating means no pressure reduction required. Direct injection into pressurized lines.
Remote and Unattended Sites
Wide temperature range and all-stainless construction mean reliable operation without frequent maintenance.
Low Pressure Drop – Why It Matters
Every bar of pressure drop costs you money.
Higher pump energy consumption
More heat generated in the system
Potential cavitation in sensitive fluids
The G1.0SS minimizes pressure loss. Its internal flow path is optimized to reduce resistance while maintaining measurement accuracy. Your pump works less. Your energy bill drops. Your system runs cooler.
Low Noise Emission – Why You'll Notice
Mercaptan injection systems often operate near populated areas or within enclosed facilities.
The last thing you need is a high-pitched whine from a flowmeter.
The G1.0SS uses precision-meshed gears that rotate smoothly and quietly. No turbine blade whistle. No ultrasonic hum. Just quiet, reliable measurement.

One Question
Would you trust a signal – or trust a gear?
Signals drift. Sensors foul. Electronics age.
Gears just turn. And every turn is a fixed volume.
In mercaptan injection, there is no room for doubt.
