Gn Flow Meter is a leading manufacturer of microfluidic measurement and control instruments.
You're mixing resin. You're dosing paint. You're feeding a reactor.
One wrong flow reading – and the whole batch is scrap.
Not because the pump failed. Not because the pressure dropped.
Because your flowmeter couldn't handle the viscosity.
Most flowmeters lose their nerve when the fluid gets thick. Turbine meters slow down. Electromagnetic meters choke on non-conductive media. Ultrasonic meters give up on paint.
The P5 doesn't care.
It's a positive displacement oval gear meter. It measures by trapping fixed volumes – not by flow velocity, not by conductivity, not by sonic reflection.
Viscosity changes? Temperature swings? Intermittent flow?
The P5 reads them all the same. Because it measures volume, not speed.
| Your Fluid | Why Others Fail | Why P5 Works |
|---|---|---|
| Polyurethane resin | Gets thicker as it cures – turbine meters lose accuracy | Positive displacement – viscosity has zero effect |
| Paint and coatings | Contains pigments – clogs turbine blades, fouls sensors | Oval gears – self-wiping action keeps them clean |
| Adhesives and sealants | Stringy, non-Newtonian – ultrasonic can't penetrate | Mechanical metering – doesn't rely on signal reflection |
| Heavy oil | Too thick for electromagnetic, too slow for turbine | High-torque gear design – handles it effortlessly |
| Feature | What It Means for You |
|---|---|
| 5~5000 L/min | One meter covers pilot lines and production lines |
| 0.5% accuracy | Every batch consistent – no over-dosing, no under-dosing |
| All-stainless (PSS) | No corrosion, no swelling, no degradation from solvents |
| 8 bar rating | Handles pump pulsation and system backpressure |
| 5~26 VDC | Direct to PLC – no extra power supply needed |
| -40~80°C | Works in cold storage, works in hot reactors |
| Miniature footprint | Fits into tight skids where others won't |
"Low pressure drop" – means your pump works less, your energy bill drops, and your system runs cooler.
"Low noise" – means no high-frequency whine. Your operators will thank you. Your neighbors will too.
"Intermittent measurement" – means even when the pump stops and starts, the totalizer keeps counting. Every drop. Every time.
No recalibration – Stainless gears don't wear. What you set on day one stays true on day 1,000.
No surprises – When viscosity spikes, the P5 doesn't drift. It just keeps reading.
No second-guessing – Your batch data is real. Not estimated. Not corrected. Real.

Would you rather trust a signal – or trust a gear?
Signals can drift. Sensors can foul. Electronics can fail.
Gears just turn. And every turn is a fixed volume. No math. No interpretation. No excuses.
