problem 2
In the following industrial process shown in Figure 2, consider the loop control strategy
most suitable closed that it deems convenient making use of the ISA 5.1 standard for the
variables: level and flow
Control strategy to implement:
Check H1 and H2 levels in TK1 and TK2 tanks
Control the flow from TK1 output to TK2 input
Your answer should include a PI&D diagram for the complete solution
Note: As a control strategy is requested, all manual valves in the process
shown should be replaced with automatic control valves and add all the
measurement and control elements according to ISA 5.1
Measurement instrumentation to be used:
TK1 level: Level sensor by static pressure principle
TK2 level: level sensor by ultrasound principle
Flow: CONE type differential pressure sensor.
