Prima

Flap-type or sight flow indicator with option of flow monitoring

Prima is a flap-type flow indicator with high resilience and suitable for operating temperatures of up to +100 °C at an operating pressure of up to 10 bar. The flap indicator is recommended in particular for cloudy and opaque liquids and transfers the motions of the indicator via a magnet attached to the flap. That shows the flow on the scale. In addition to this, an optional inductive contact also makes flow monitoring possible in the measurement indicator.
