The accessory HM 162.59 is intended as carrier for instruments, e.g. the pitotstatic tube HM 162.50 or the level gauge HM 162.52. Using the carrier, the used instrument can be moved to nearly every point of the flow.
The instrument carrier consists of a frame where the instrument can be fixed. This frame can be moved on rollers along the entire length of the experimental flume. Transverse to the flow, the frame can slide along rails to any position.
The exact determination of the position of the used instrument is realised with scales. The instrument carrier includes a scale with pointer transverse to the flow. Parallel to the flow, a pointer of the carrier is used to indicate the position on the scale of the experimental flume.
