Mount the RQ-30 at the monitoring site
The RQ-30 is mounted to a tube Ø34…48 mm with the supplied U-bolts. For alternative mounting methods please contact Sommer Messtechnik.
The RQ-30 must be installed parallel to the water surface! The angle between the water surface and the device must not exceed ±2.5°.
As illustrated in Figure 16 the RQ-30 must be installed parallel to the water surface in both directions: along and perpendicular to the water flow. Additionally, the sloping angle has to be entered in the parameter River inclination. The sloping angle is always entered as a positive value, irrespective of the viewing direction of the sensor.
In tidal situations where both flow directions occur, the RQ-30 should always be mounted horizontally and River inclination should be set to 0.
