Installation 6-31
Setting up the Measurement Location
If possible, install the measurement device in front of the regulating unit. This setup
may not acknowledge or consider the response time of the control system. However,
it does prevent or minimize hydraulic disturbances from external vortices
downstream of the regulating unit.
Figure 6-41 Setting up a controlled system, such as a discharge control
If this installation configuration is not possible, install the measurement
device downstream of the slide valve a distance of at least 12 times the
maximum pipe height (Figure 6-42). In addition, inspect the hydraulic
conditions at the location before installing the equipment. To ensure
suitable measurement conditions, establish an adequate distance or
implement appropriate calming measures (such as deflectors or similar
devices) between the gate valve and the measurement location
downstream.
