Stainless Steel Flow Sensor Probe
Figure 1. Two Flow Sensor Probes Mounted in “X”
Configuration.
Description
The Siemens Stainless Steel Flow Sensor Probe is
used with differential air pressure sensing devices, to
measure flow with differential pressure across a duct.
The probe is used in situations where a terminal box
manufacturer-supplied sensor (flow pick-up) is not
available, or where the existing flow pick-up has been
damaged. In addition, it can be used with venturi air
valves or corrosive air streams as long as the probe is
installed far enough upstream or downstream of the
venturi valve to avoid excessive turbulence.
Features
• Thin steel construction.
• Mounting flange is easily bent to conform to
round, oval or rectangular ducts.
