Figure 21. Position of pressure sensor
If pressurizing a long pipe with many outlets, the best place for the sensor would probably be
halfway down the pipe (Position 2). However, sensors might, for example, be placed directly
after the pump. This will give the right pressure directly after the pump, but farther down in the
pipe the pressure will drop depending on the flow.
