Product Application
The FM500 gear flow sensor is widely used in various industries for precise low-flow measurement. Applicable media include: additive fuels, flotation cells in water treatment, corrosion inhibitors, catalysts, and emulsions
Some high-viscosity media such as chemicals, oils, greases, fragrances, adhesives, solvents, inks and pesticides. The application industries include automobiles, aviation, mining, power, chemical engineering, pharmaceuticals, food, coatings, petroleum, environmental protection, printing and other industries. It is particularly suitable for heavy oil. Flow measurement of high-viscosity media such as polyvinyl alcohol and resin.(Capable of measuring fluids with a viscosity as high as 10,000 Pa.s) Small in size, light in weight, low in vibration and noise during operation, and stable in operation. It can also be used to measure the tiny flow rate of small pipe diameters. It features a small starting flow rate, a wide range ratio, and is suitable for measuring the flow of liquids with large variations. The measurement accuracy is not affected by pressure and flow rate changes. It has stable performance, a long service life, and a large flow capacity.
