Essentials of Instrumentation for Monitoring and Control



SKU: ce56 Category:


Proper use of instrumentation is an integral element of monitoring and control in facilities throughout the chemical process industries (CPI). This Chemical Engineering PDF guidebook provides a diverse collection of articles related to the specification, operation, maintenance and troubleshooting of instrumentation systems used for monitoring temperature, pressure and level.

Included are several engineering articles related to flowmeters. It covers important aspects of sensors for control valve positioning, rupture disks to provide reliable pressure relief, monitoring systems for aboveground and underground piping, aspects of monitoring distillation performance and more. Here you will find concepts of safety-instrumented system (SIS) design and operation.

Delivered in a PDF, 214 pages.
