The ST50 thermal mass flow meter from Fluid Components International (FCI) is now ATEX-approved for potentially explosive environments classified as EExd IIC T4, which makes it suitable for applications in hazardous plant areas in the European Community and elsewhere worldwide.

As an air/gas flow meter with ATEX approval, FCI’s ST50 has been designed to isolate its electronics from the danger of volatile gases, including hydrocarbons.  The ATEX directive specifies design criteria for flow meters and other electrically powered instruments to help prevent explosions and fires when combustible gases are present.

The flexible ST50 features a wide flow range. It measures air flow from 1 to 125 SFPS (0.3 to 38 NMPS), nitrogen from 1 to 150 SFPS (0.3 to 46 NMPS) and compressed air from 4 to 400 SFPS (1.2 to 122 NMPS).  Accuracy is +1% of reading, +0.5% of full scale, with repeatability of +0.5% of reading.   It operates at temperatures from +40 to 100°F (4 to 38°C).
