Volume flow measuring device for process applications, FLOWSIC100 Process


With the FLOWSIC100 EX-Z2-PN16 / CL150 gas flow measurement 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.

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.

At a glance

  • Corrosion-resistant transducers made of stainless steel or titanium
  • Explosion-proof version for applications in Zone 2 (ATEX)
  • Process pressure up to 16 bar
  • Hermetically sealed ultrasonic transducers
  • Integral measurement over the duct diameter
  • Automatic function control with zero and span point check

    Your benefits

  • Reliable and accurate measurement also at low gas velocities
  • No movable parts, therefore low maintenance
  • Measurement independent of pressure, temperature and gas composition
  • Approved for usage in hazardous areas Zone 2 (ATEX)
  • Representative measuring results due to measurement across the whole duct diameter
  • No influence on the gas flow due to contact-free measurement
  • User-friendly operation and device diagnosis via MCU control unit and SOPAS ET operating software
