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.

• Design ensures the sensor is sealed, locked and pre-loaded to the
opposite wall, regardless of changes in pipe diameter due to pressure,
temperature or mechanical vibrations.
• Leak-proof…compensates for differential in packing and body growth
rates due to increased temperatures.
• Increases sensor strength (eliminates the need for an opposite wall
support). A locked, pre-loaded sensor is four times stronger than
a non pre-loaded, cantilevered sensor.
• Spring Lock is engineered with three standard spring configurations
equivalent to ANSI class 150#, 300# and 600# ratings.
• By loading the sensor and packing independently, the sensor can
move axially to maintain a precise load on the pipe wall.
