The Most Accurate and Reliable Technology
for Measuring Gas, Liquid and Steam…
The extended range Verabar® is engineered
for liquid, steam and high velocity gas
flow measurement in larger pipe
sizes, up to 60” (1524mm). 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.

Synchro-Drive Description
Synchro-Drive is standard on all – 20 sensors. Two drive
rods are coupled together by a protected chain drive
system. Turning either drive nut simultaneously rotates
both rods.
Synchro-Drive Benefits
• 95% faster and easier insertion and retraction
• Equal load distribution over both rods maintains sensor
alignment and eliminates binding
