ISA Certified Control Systems Technician (CCST) program
Certified Control System Technicians (CCSTs) calibrate, document, troubleshoot, and repair/replace instrumentation for systems that measure and control level, temperature, pressure, flow, and other process variables.
If a flow sensor is connectied to the DCS system and the flow is displayed in volumetric units, what calculation would been to be performed in the control system to display the flow rate as a mass flow rate?
A. mass flow rate = volumetric flow rate × pipe cross-sectional area
B. mass flow rate = volumetric flow rate × sensor input in mA
C. mass flow rate = volumetric flow rate × fluid density
D. mass flow rate = volumetric flow rate / pipe cross-sectional area
