Flow switch series from Cynergy3. These flow switches are reed switch based and can monitor the flow of liquids up to 10bar in pressure. This series of flow switches can be mounted horizontally or vertically and have minimal flow restriction. Flow switches are ideally used in water but can be used in weak acidic liquids.

Mainly for use with hot or cold water, however they may also be used with a wide range of chemicals
Pressure rating 150psi maximum
Switching current 1A dc or ac (rms)
Switching voltage 240V dc or ac (rms)
Switching power 15W (15VA) resistive loads
Operating temperature 85°C maximum
Vertical or horizontal mounting
Standard compression or push fit fittings
WRAS approved for use in cold water
Complete with a 250mm lead

Not to be used in any chlorinated liquids

To measure the liquid flowing through your system, turn to this Sensata Cynergy3 switch. If the flow rate exceeds 3.75l/m (litres per minute), the 'normally open' (NO) contacts will close, sending a signal to the relay control output and enabling you to stop the flow. Install this switch in your wider system to regulate flow automatically, improving safety and efficiency. You can also release flow when the rate drops below 1.4l/m, making it possible to control the liquid in your system without restricting it entirely.

• Operating temperature range of -20°C to +85°C for use in extreme conditions
• Switching voltage of 240V AC or 120V DC offers flexible power supply options

Sensata's F22 series switches have a maximum operating pressure of 10 bar. This makes them suitable for heavy-duty applications.

This switch is designed for liquids only and should not be used with significant amounts of solid particles. It's suitable for weak acids (up to a concentration of 5%) but not for any type of chlorinated liquid such as bleach.
