Research on the Field Test Methods of Flow Rate and Water Level of Urban Drainage Pumping Stations

The flow rate and water level measure is one key work of the pumping station field test. And the reliable, applicable, economic and effective measurement method and instruments are the key decisive factors of the field test. The urban drainage pumping stations usually pump sewage, and its inlet structure and outlet structure generally use closed arrangement. These make the flow rate and water level measurement of the field test become complicated. Based on the characteristics of urban drainage pumping station, this paper analyzed the measurement methods of flow rate and water level parameters of the field test for urban drainage pumping station. In combination with a field test case for an urban drainage pumping station, this paper demonstrated how to choose the reliable, applicable, economic and effective measurement method to measure flow rate and water level parameters.
