Abstract

A siphon weir having a downwardly directed inlet port and a lower lying outlet port (18) on the downstream side connected with it by means of an approximately S-shaped siphon line (13) contains a ventilating mechanism for improving the regulating behavior. The ventilating mechanism is preferably constructed as a linear, sloping ventilating pipe (46), which is led out of the interior of the container to be regulated through the rising leg of the siphon line (13) and issues below the siphon top in the downwardly leading falling leg of siphon line (13). A diverter (28) for floating material can be mounted on the upper end of ventilating pipe (46).
