A tube separator (1) having a shut-off means for separating an inlet side (2) from an outlet side (3) is provided. In order to prevent flutter of the shut-off means (4) in a pressure region changing over the shut-off means, a control valve (10) controlling the shut-off means (4) is provided. The control valve (10) is designed such that the pressure required for changing over from a first opened position to a second shut-off position is smaller than the pressure for changing over from the second into the first position.

A mobile metering apparatus is provided for metering into a liquid stream or flow an agent which is to be metered or dosed in a quantitative proportional relationship. The metering apparatus contains liquid meter through which passes the liquid flow and a metering pump connectable to a dosing agent reservoir on the input side thereof and to a metering location at the output side thereof. The metering pump meters the agent from the reservoir into the liquid flow as a function of signals supplied by the liquid meter. The liquid meter is installed in a short conduit portion provided with an inflow connection and an outflow connection. The short conduit portion, liquid meter and metering pump are mounted at a supporting frame enclosing the aforementioned members on all sides. The drive of the metering pump is accomplished by the pressure of the liquid flow. In this way a multifarious usable metering apparatus is realized which is independent of an external power supply and which is particularly suitable for decontamination and detoxication purposes.
