Installation conditions for the sensor for flow measurements
• Mount the measuring device on the upstream side immediately above the maximum
upper water level H
max
• Take the blocking distance into account
• Position the measuring device in the center of the flume or weir
• Align the sensor membrane so that it is parallel to the surface of the water
• Observe the installation clearance of the flume or weir
• Enter the "flow - level" ("Q/h curve") linearization curve via the FieldCare operating
program or manually via the local display
