Electronic flow switch With display WIKA

Electronic flow switch With display WIKA, for liquid media Model FSD-3

Flow switches are used for the display and monitoring of the flow of liquid and gaseous media. The instruments feature a high switching accuracy and functional safety, low switch hysteresis and continuous switch point setting by the operator.

The wide selection of WIKA flow switches also includes viscosity-compensated models and ATEX-certified instruments for use in hazardous environments.

Applications of the flow switch

• Control of cooling lubricant systems
• Monitoring of cooling circuits
• Control of filter units
• Dry run protection in pumps

Special features of the flow switch

• Reliable flow monitoring of liquid media
• Switching and analog outputs for flow, temperature, and diagnostics
• Easily parameterisable via the local display
• Free from wear, without any moving parts in the medium

The successful design and the excellent functionality of the WIKA switch family were already confirmed by winning the “iF product design award” for the pressure switch model PSD-30.

The robust LED display has been designed using 9 mm high characters (the largest possible) and with a slight incline in order to make reading the flow as easy as possible from greater distances.
The 3-key operation makes simple, intuitive menu navigation possible, with no need for additional assistance. The menu navigation conforms to the VDMA standard.

Free from wear

The FSD-3 flow switch operates on the basis of the calorimetric measuring principle. This guarantees a wear-free flow measurement without any moving parts in the medium.

Flow monitoring of liquid media

The FSD-3 flow switch enables the reliable and process-safe monitoring of the flow of liquid media. When the flow is above or below the set value, the switching output activates the downstream regulator or control. Damage and production losses through degradation of pumps, tools, and spindles can thus be avoided.

Temperature monitoring

The medium temperature can be monitored by means of a temperature output, without the need for equipping another measuring location.

Diagnostic function

The optional diagnostic function of the flow switch reliably outputs a warning when a sensor defect is detected. The switching output can be used to trigger a downstream safety function.
