Fluid Sentry

Remotely Monitors And Reports Coolant Flow And Temperatures As Well As Piping System Integrity

A key component of JASC’s back-up liquid fuel system reliability design is the Fluid Sentry.

With cooling water piping infrastructure having a life expectancy of decades and turbine major maintenance intervals of every 4 to 5 years, the ability to remotely monitor the performance and integrity of the cooling system has become an important part of achieving improved liquid fuel system reliability.

JASC’s Fluid Sentry remotely monitors and reports coolant flow and temperatures as well as piping system integrity. This provides peace of mind that adequate coolant flow is available to critical system components such as JASC’s superior actively cooled valve designs allowing for extended operational intervals.

The Fluid Sentry is sensitive enough to detect small flow discrepancy between the cooling water supply and return lines. The Fluid Sentry is utilized for either basic water-cooled check valve systems or can be used on more advanced future liquid fuel reliability systems such as water-cooled 3-way purge valves and ZEE (Zero Emissions Equipment).

Best of all it is a simple retrofit for adding Monitoring, Protection, and Notification on any previously installed water-cooled valve piping infrastructure.
