The Sentry® AutoVREL Flow Controller allows users to automate new or existing
sample panels through a well-appointed device that controls sample panel flow
based on feedback from a non-contact flow meter. With the AutoVREL “smart”
function, the operator only needs to set the desired sample flow and the system
automatically adjusts to changes in the sample pressure.
MODEL
AV-101
BENEFITS
Power plants that frequently cycle or have sliding pressures require lab technicians
to manually adjust the variable pressure-reducing element (VREL) in their sample
panels to maintain EPRI-recommended sample velocity. With reduced or reallocated
staff resources, interest has increased in automating these redundant tasks. The
Sentry AutoVREL Flow Controller has been developed as an alternative to the fullfeatured Sentry Sample Sentry II to offer an additional sample panel automation
option.
