Title:
PROCESS FLOW CONTROL CIRCUIT
Document Type and Number:
Japanese Patent JP2004225699
Kind Code:
A
Abstract:
To provide a process flow control circuit for automatically maintaining a fixed fluid flow by monitoring the power and pressure difference of a fluid transport apparatus in a fluid velocity control mechanism for a fluid velocity circuit including the fluid transport apparatus, such as a pump and a compressor.
A controller is programmed by a software command to automatically sample data for reflecting the power and pressure difference of the fluid transport apparatus, and automatically maintaining a fixed fluid flow passing through the fluid transport apparatus, based on the power and pressure difference of the fluid transport apparatus.
