General Purpose Verabar Sensor Models-Flowmeters

V100 and V110  The V100 is our most economical Sensor.  Mounted through a simple tube fitting, it is used most commonly on air and water utility pipes with lower fluid velocities. The V110 includes support on the opposite wall of the pipe.
V150  The V150 is our best-valued sensor.  This sensor is mounted through a patented spring-loaded packing gland.  It can handle greater fluid velocities than the V100 and can be resealed hundreds of times. The V150 does not require opposite end support and  is ideal for steam service.

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.
