EGE offers thermodynamic flow controllers without moveable parts, which means they are robust and resistant to soiling. Controllers for fluids such as water, glycol mixtures or chemicals are as much part of the product range as sensors for gases such as air and carbon dioxide. Intrinsically safe sensors based on ATEX for explosive and hazardous areas are also available. Additional variations consist of high temperature sensors up to 160 °C, special sensors made from such materials as Hastelloy, Monel, titanium and tantalum with high resistance to chemicals, and programmable flow sensors with digital displays. The flow controllers are either screwed into the side of the pipe or added to the line itself in the form of inline sensors.
