Technische Unterlagen HydroLimiter®


Float-controlled penstock – DN 150 top DN 400 – for dowelling

For controlling discharges or limiting maximum water level. A low-cost alternative when accuracy of the discharge is of secondary importance or when optimisation of channel volume, e.g. in cascades, is desired.

  • complete stainless steel construction
  • material 1.4301 (AISI 304)
  • optional 1.4571 (AISI 316)
  • robust construction
  • easy to fit with no wall clearance
  • extremely cost-effective
  • complete with stainless screws, dowels, etc. and sealing materials

HydroLimiter „OW“

(upstream installation)


The discharge characteristics of the HydroLimiter in upstream installation can be adjusted on site with help of the discharge flow diagram, see the following table for resulting maximum discharge volumes. Backwater will influence the discharge characteristics and max. discharge values.

HydroLimiter „UW“

(downstream installation)

HydroLimiter in downstream installation serves to limit the maximum water level, for instance in order to use storage areas in preceding channels. The discharge characteristics should be clarified with Steinhardt.
