Broadley James Corporation Flow Controller S/601 Flow Controller

• Precise gas flow regulation in laboratory and pilot-scale bioprocess systems.
• Controlling inert gas sparging rates in bioreactors and fermenters.
• Managing gas mixtures for cell culture and microbial fermentation.
• Maintaining specific backpressure in chromatography and filtration systems.

Typical flow range

Units of this type commonly handle flow rates from millilitres per minute to several litres per minute, depending on the specific sensor and valve configuration.

Control method

Often features PID (Proportional-Integral-Derivative) control for stable and responsive flow management.

Power supply

Typically requires a standard laboratory power supply, commonly 24V DC or 100-240V AC, with specific requirements varying by model.

Interface

May include local display and keypad, as well as digital communication ports (e.g., RS-232, RS-485, Ethernet) for integration with control systems.

Input/Output signals

Commonly accepts analogue input signals (e.g., 0-5V, 4-20mA) for setpoint control and provides analogue output for actual flow rate.

Process connection

Typically uses standard laboratory tubing connections or threaded fittings suitable for gas lines.

• What is the primary function of a flow controller like the Broadley James S/601?

  Its primary function is to accurately measure and regulate the flow rate of gases or liquids, maintaining a user-defined setpoint despite variations in upstream or downstream pressure.

• Is this unit suitable for liquid flow control?

• What does 'Power-On Verified' mean for a used unit?

• What maintenance is typically required for this type of equipment?

• Can this unit be integrated into an existing control system?

Pneumatic units for liquid handling are valued for their reliability, safety in sterile environments, and low maintenance demands. Buyers typically prioritize checking for air leaks, hose condition, and valve responsiveness when purchasing used equipment. Industry feedback highlights their durability and cost effectiveness compared to electric alternatives. Key considerations include compatibility with existing systems, calibration history, and whether regulators remain accurate. These units perform consistently across laboratory and pharmaceutical applications when properly maintained.
