The invention discloses a square cabin type filtering and metering station. The square cabin type filtering and metering station comprises a square container cabin which can be transported along with a vehicle. A pipeline provided with a liquid inlet end and a liquid outlet end is installed in the square container cabin. A filtering and metering device used for treating liquid passing through the interior of the pipeline is connected to the pipeline in series. Brake valves used for controlling communication between the filtering and metering device and the pipeline are arranged at the two ends of the filtering and metering device respectively. The filtering and metering device comprises a flowmeter, a filter separator, a rough filter and a pipe cleaner receiving and sending device. According to the square cabin type filtering and metering station, the square container cabin is used as an installation base of the filtering and metering station so that the filtering and metering device required by the whole filtering and metering station can be assembled in advance, then movement along with the vehicle is achieved by transporting the square container cabin, and the square cabin type filtering and metering station can be erected in a short period of time to be put into use; operation is easy and safe, and filtering and metering work of the pipeline is greatly facilitated.
