CCM Series Adjustable Flow Monitor

CCM flow switch: precision at minimal flow

The CCM flow switch excels in situations where a standard flow sensor falls short. We have optimised the design for applications where the ratio between normal flow and switch point is large (10:1 or more). This keeps the monitor insensitive to fluctuations in the system, while the sensor retains its accuracy at the desired switch point.

Why use the CCM series?

The CCM flow switch offers a unique combination of chemical resistance and sensitivity. Because the sensor is so reliable, technicians frequently use it in:

• Gas chromatography: accurate monitoring of carrier gases.
• Analysers: reliable flow detection for sample systems.
• Corrosive chemicals: safe use with liquids that attack metals.
• Filter maintenance: signalling of reduced flow due to contamination.
• Gas generators: checking the constant output of gases.

Innovative operating principle

The CCM series uses a unique magnetic repulsion system instead of a mechanical spring:

1. Magnetic repulsion: at zero flow, the magnetic piston is held in place by the repelling force of a fixed magnet.
2. Flow bypass: as soon as the flow increases, the piston moves. The system also routes a large part of the flow through a bypass to minimise pressure drop.
3. Contact: at the exact set point, the piston activates a hermetically sealed reed switch. This construction also guarantees a completely interference-free signal.

Installation and custom work

The CCM flow switch must be mounted vertically with the inlet port facing up. For optimal service life and to prevent blockages in the fine measuring channels, the use of a 10 micron filter is strongly recommended.
