SOLUTION: This sewage weighing device has a water storage chamber 3 for storing sewage supplied together with air and a weighting chamber 8 having a weighing notch 12 and an adjusting notch 13. Then, the water storage chamber 3 and the weighing chamber 8 are partitioned by a stream lining plate 2, an upper space of the water storage chamber 3 is sealed by a cover 4, and air in the water storage chamber 3 is made to flow out to the vicinity of the weighing notch 12. A freely opening/closing air bleeding cap 5 is installed in a part of the cover 4, and an air flowing hole 17 is formed in the stream smoothening plate 2 between the water storage chamber 3 and the weighing chamber 8.
