The Most Accurate and Reliable Technology
for Measuring Gas, Liquid and Steam…
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.

Flow Calculation
All Verabar applications require a flow calculation to verify
the DP, pressure and temperature limits, structural limits
and to size the transmitter. The Veracalc PC Program
is for use by representatives and end users. It is easy
to operate and includes steam tables.
Retaining Hardware
• Eliminates drive rods
• Safety cable limits retraction length to ensure proper sealing
of packing gland
• Retaining ring loads sensor to opposite pipe wall
