Developed from aerospace technology, the Verabar averaging pitot flow sensor provides unsurpassed accuracy and reliability.
The V200 can be inserted
and removed under pressure. Use this model when you can not shut down the
pipe to insert the sensor. The V200 is the most frequently sold hot-tap
model. It is available in single rod and double rod units for high
The V350 can
be inserted and removed under pressure. The insertion mechanism (Jack) can
be removed and used on multiple pipes. The Jack can be stored in a
dry location away from the elements making it ideal for outdoor and
The V400 can
be inserted and removed under pressure. Similar to a V200 except it has a
flanged connection to the pipe for added sealing capability. When
plant regulations require a flanged hot tap connection, the V400 is the
correct model to use. It is available in single rod and double rod units
for high pressure.
Developed from aerospace technology, the Verabar averaging pitot flow sensor provides unsurpassed accuracy and reliability. With its solid one piece construction and bullet shape, the Verabar makes flow measurement clog-free and precise. The unique sensor shape reduces drag and flow induced vibration. And the location of the low pressure ports eliminates the potential for clogging and improves signal stability.
How the Verabar Works
The Verabar senses the natural Averaged Pressures created by the velocity profile of the fluid. When the fluid impacts the sensor, it creates a high pressure zone, greater than the pipe static pressure, in front of the sensor.
As the fluid moves past the sensor, it accelerates and a low pressure zone is created to the sides and rear of the sensor. Alternate vortices are shed as the fluid separates from the sensor and a partial vacuum is formed at the rear of the sensor.
Multiple ports are positioned in the high and low pressure zones and an averaged differential pressure is produced.
