Abstract

The invention discloses a positioning device and positioning method for an electromagnetic current meter. The positioning device is connected with an electromagnetic current meter fixing frame, and the electromagnetic current meter is arranged on the electromagnetic current meter fixing frame. The positioning device comprises an air pump, a plurality of elastic tubes, a plurality of metal sleeves and depth indicating plates. The metal sleeves are arranged on all the elastic tubes and sequentially connected in an insertion mode, and the depth indicating plates are arranged on the metal sleeves of the upper portions of all the elastic tubes. The elastic tubes are in clearance fit with the metal sleeves, the metal sleeves located at the lower ends of the elastic tubes are fixedly connected with the fixing frame of the electromagnetic current meter, the lower ends of the elastic tubes are connected with the metal sleeves in a sealing mode, and the upper ends of the elastic tubes are connected with the air pump through connecting tubes. The positioning device and positioning method have the advantages of being capable of accurately positioning the electromagnetic current meter, guaranteeing stability of the electromagnetic current meter and effectively improving accuracy and reliability of detection data.

Description

technical field [0001] The invention relates to the technical field of water flow velocity detection, in particular to an electromagnetic current velocity instrument positioning device and a positioning method capable of accurately positioning the electromagnetic current velocity instrument, ensuring the stability of the electromagnetic current velocity instrument, and effectively improving the accuracy and reliability of detection data. Background technique [0002] Electromagnetic flow meters are usually placed in rivers, channels, streams or oceans to test the flow rate of water, etc. Because the electromagnetic current meter is placed in the water, it is easy to cause the electromagnetic current meter to swing and drift with the water flow, resulting in the electromagnetic current meter cannot be accurately positioned in the water flow at the depth that needs to be detected, and the accuracy and reliability of the data detected by the electromagnetic current meter are rel...
