The scenario
A brewery automates beer transfer from a holding tank through a filter into a carbonation tank, then to bright beer storage, using flow transmitters and indicating controllers to modulate two control valves.
What is in this drawing
Read the decisions behind it.
01
Use two independent flow control loops for upstream and downstream transfer lines
02
Select diaphragm-actuated control valves with fail-closed action on beverage lines
03
Measure flow after each control valve to stabilize batch transfer rates
Reuse for any food/beverage P&ID where inline liquid transfer through filters, tanks, and pumps requires automated valve modulation with electric and pneumatic instrument loops.
