Continuous in-situ measurement of velocity, temperature and absolute


pressure of gas flows in pipelines

APPLICATION YOUR BENEFITS AT A GLANCE


The use of the measuring principle of dynamic pressure
• probe and operating unit integrated in one
and PT100 assures a device which is easy in design
compact device
and operating as well as the realtime monitoring of the
measuring parameters. • local diagnosis of system state by integrated
graphic display
The operating and display unit is integrated in the
• real-time display with line diagram
weather protection casing. On the high-quality display
all measuring values, status information and parame- • output of volume flow at standard reference
conditions possible
ters are displayed.
• easy mounting and very low maintenance
Optionally, the absolute pressure at the measuring requirement
point can be measured continuously by an absolute
