V450 Verabar Pitot Tube Flow Sensor

Brand: Yokogawa Electric Corporation

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 leak proof and precise. 

The unique sensor shape reduces drag and flow induced vibration. 

The location of the low-pressure ports eliminates the potential for clogging and improves signal stability.
