Systec Deltaflow DF25 Averaging Pitot Tube
The Systec DF25 is a very robust and durable sensor, it can be used in pressures up to 250bar and temperatures up to 1240c. With its large 8mm diameter pressure port holes it is far more resistant to blockages against standard DP systems.
The Systec DF25 is a tailored solution for your needs, it can be supplied with temperature sensors and absolute pressure cells if your application requires. Flowline can also provide a suitable DP Cell or mass correcting Multivariable Transmitter.
How it works
The DF25 uses the well-established Differential Pressure (DP) measurement method. The DF25 is an insertion Averaging Pitot tube which is install across the internal diameter of the pipe. The DF25 creates a very small, yet measureable differential pressure, that is measured and output via a DP Cell or Multivariable Transmitter
The DF25 comprises of the Pitot tube itself and the connection piece that is normally supplied to you and you weld it on to your pipe. The DF25 Pitot is then inserted through the connection piece and will be held in place via cut ring or flange connection. All that is then require is to mount the DP Cell or Multivariable Transmitter
- Very Low Line Restriction - pressure loss is typically just a few mbar
