Precision Flow Meter for Automotive Antifreeze – CX-M5.2-SS Oval Gear Flow Meter
Why Antifreeze Needs a Special Flowmeter
Automotive antifreeze (glycol/water) is tough to measure. Viscosity changes with temperature. Additives can corrode metals.
Pressures run high. Low flow rates are common in idle or partial-load conditions.
Most flowmeters fail here. Turbine meters wear out. Thermal sensors drift. Ultrasonic types lose accuracy at low flow.
The CX-M5.2-SS Oval Gear Flowmeter is built specifically for this job.

What Makes It Different
Positive Displacement Design
Measures every drop directly. Accuracy stays at ±1% regardless of viscosity or pressure changes.
SS316 Housing
Resists corrosion from glycol and additives. Handles 32 bar without deformation.
PPS Gears
Low friction, chemically inert, stable across -30°C to +80°C. No metal-to-metal contact means no galling or seizing.
Wide Power Range
Works on 5V, 12V, or 24V systems. No extra converters needed.
Built-in Filter
Protects gears from debris. Extends service life.
High Resolution
0.11 mL/pulse captures even the smallest flow changes.
Where It's Used
EV battery thermal management
Engine test benches
Fuel cell cooling
Industrial chillers
Mobile off-highway equipment
Installation Tip
Mount with inlet filter facing flow. Keep straight pipe upstream when possible. For bidirectional measurement, request optional pickup board.
Why Choose CX-M5.2-SS?
It delivers reliable, repeatable data where other meters struggle. Compact size. Rugged materials. True ±1% accuracy from 5 mL/min
to 100 mL/min. No bearings to wear out. No drift from temperature or viscosity shifts.
