With the FLOWSIC100 EX-Z2-PN16 / CL150 gas flow measuring devices measurements can be carried out at pressures up to 16 bar - also in hazardous areas Zone 2. The ultrasonic transducers have a high acoustic power and are suitable for measurements in large duct diameters up to 1700 mm or for difficult gas compositions. The sender/receiver units are available as hermetically sealed versions made of stainless steel or titanium. A retraction mechanism allows removal of the sender/receiver units during plant operation.
The standard system contains a MCU control unit and 2 sender/receiver units. The MCU is used for input and output of signals, for calculation of reference values (standardization) or mass flows, as well as user-friendly LCD interface.
