500 BP Series Adjustable Flow Monitor

500 BP flow switch: optimal control via bypass technology

The 500 BP flow switch stands out for its ease of use and low minimum working pressure. Because technicians can easily set the switch point manually via a control valve (vane), this monitor offers maximum control in dynamic process environments. In addition, the inline 180-graden port configuration ensures seamless integration into existing horizontal pipework.

Why the 500 BP series is the right choice

Thanks to its robust construction, engineers use the 500 BP flow switch in demanding sectors. The monitor performs excellently in the following applications:

• Vacuum systems: For monitoring critical gas flows.
• CVD furnaces: For monitoring cooling water circuits in semiconductor processes.
• Biomedical instruments: For safe flow detection in laboratory setups.
• Marine cooling systems: Because of their resistance to harsh conditions.
• Wet stations: For monitoring process liquids.

How does the bypass mechanism work?

The operating principle of the 500 BP flow switch is as simple as it is effective:

1. Flow activation: As soon as flow occurs, the liquid or gas pushes the magnetic piston up in the bypass bore.
2. Switching: This displacement activates a hermetically sealed reed switch, safely encapsulated outside the media path.
3. Adjustability: The user controls the bypass flow manually. This allows the switch point to be matched very accurately to the system requirements.
4. Reset: When the flow decreases, the piston drops back and immediately deactivates the switch.

Installation and custom work

Preferably mount the 500 BP flow switch vertically (with the wires pointing up) in a horizontal line. We also always recommend using a 100 micron filter to prevent contamination of the bypass valve.
