Metal pipe rotameter (SF 20)

Intellectual metal rotameters SF 20 (metal float) are a common device for measuring variable consumption in industrial automation and management process. It has compact dimensions, a wide range of measurement and ease of operation. It can be used to measure the consumption of fluids, gases and steam. Especially suitable for measuring flow at low flow rate, low costs, high temperatures, high pressure, aggressive media and non -conductive media.

Types of product use

The flow meter of the SF20 series with an intellectual float in a metal tube can measure the consumption of various environments, especially suitable for measuring small and medium costs with a low reinolds in the pipelines of small and medium diameter. It is characterized by small and stable pressure losses, high sensitivity, a wide range of measurements, a clear indication of indications and approximately linear scale. The design is simple, has the optimal cost and ease of operation and maintenance. Also able to measure the consumption of corrosion media. However, the accuracy of the rotameter depends on the temperature, density and viscosity of the measured environment.
