“A brewery wort cooling cascade: wort enters through a fail-closed control valve into a hot wort tank, overflows through a cooling tank to a cold wort tank, then exits; a level controller on the middle tank controls the inlet valve.”
接著試試Add a temperature transmitter on the cold wort tankAdd a transfer pump after the cold wort tank
這張圖裡有什麼
看懂背後的決策。
01
Use tank_atm for the three cascade vessels because the process is open to atmosphere.
02
Model the overflow connections as process lines between tank top nozzles.
03
Add a level control loop (LT-102 / LIC-102) with electric and pneumatic signal lines to modulate feed valve V-101.
Use this template for any gravity overflow cascade involving multiple atmospheric tanks in sequence, such as beverage cooling, chemical decanting, or wastewater settling.
