Separate process connections
Two additional probes are required for
temperature and pressure compensation:
• An absolute pressure sensor
This sensor must be mounted on the upstream
side of the Pitot tube.
• A temperature probe
In order to avoid disturbances of the flow
profile, this probe is to be mounted on the
downstream side of the Pitot tube. The
minimum distance between the Pitot tube
and the temperature probe is 3D.

Combined process connection for absolute
pressure, differential pressure and
temperature
• Versions of the Deltatop DP72B and DP73B
units are available with an integrated Pt100
temperature probe.
• In the case of Deltabar S, an adapter (e.g. oval
flange PZO, see TI441P) can be used to screw
a pressure transmitter or a pressure sensor
into the Deltabar S flange. The absolute
pressure sensor must be mounted at the "+"
side of the Deltabar S.
