Product introduction
Product Application:
The SN55B gear flow sensor is widely used for precise low-flow measurement in various industries.
Applicable Media:
Additives, fuels, flotation tanks in water treatment, corrosion inhibitors, catalysts, emulsifiers, oil, grease, fragrances, adhesives, solvents, ink, pesticides, and some high-viscosity fluids.
Application Industries:
Automotive, aerospace, mining, power, chemical, pharmaceutical, food, coatings, petroleum, environmental protection, printing, and more.
Especially suitable for flow measurement of high-viscosity media such as heavy oil, polyvinyl alcohol, resin (can measure fluids with viscosity up to 10,000 Pa·s).
Compact and lightweight, with low vibration and noise during operation, stable performance, and capable of measuring micro-flow in small-diameter pipes.
Low starting flow, wide turndown ratio, suitable for metering liquids with large fluctuations, high accuracy unaffected by pressure or flow changes, stable performance, long lifespan, and high flow capacity.
Measurement of resin and glue
Measurement of hydraulic oil, lubricating oil, and grease
Fuel oil measurement
Measurement of liquid nitrogen, refrigerants, solvents
Measurement of edible oil, fish oil, and food filling
Chemical and anti-corrosion fluid measurement
Fluid dosing control systems
Medium temperature: -30...80℃ (high-temp customization: 150℃)
Standard pressure resistance: 5 MPa
High-pressure customization: 40 MPa (stainless steel material)
Principle and Features
Wiring Diagram
Dimension Drawing
Selection Table
The SN55B miniature gear flow sensor features built-in dual oval gears. When fluid enters the measuring chamber, it drives the gears to rotate. The volume of liquid captured between each tooth and the chamber wall is equal.
By detecting the number of gear teeth that pass through with a specific sensor, the volume of the flowing liquid can be determined.
The SN55B gear flow sensor is not affected by the viscosity of the medium and offers high measurement accuracy and repeatability, even at the upper and lower limits of the range. It is particularly suitable for measuring high-viscosity media.
Pulse output
High pressure resistance (1.0–45 MPa)
Capable of measuring various viscous media
High accuracy and high repeatability
Wide turndown ratio (1:100)
Broad measurement range
Strong corrosion and contamination resistance (acid/alkali)
