The user assumes all risk for such usage. 5. Operating Principle The KOBOLD Rotating Vane Flow Indicator is applied where visual flow indication without flow measurement is required. A square housing with transparent windows front and back contains a rotating vane whose rotary motion, caused by the flowing medium, indicates presence of “flow”.
6. Mechanical Connection Before installation Please ensure that the actual flow-volume is in agreement with the measuring range of the unit. The measuring range can be read from the model label. Attention! On over-stepping of measuring range (more than 20 %), may cause damage to bearings and significant measurement errors may result.
7. Commissioning In order to avoid pressure peaks, the flow medium should flow slowly into the device. Note! Pressure peaks by sudden flowing, caused by single solenoid valves, ball valves or the like, can lead to the destruction of the device (water hammer!).
