Metering apparatus

摘要

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.
