Technical Field

[0001] The utility model belongs to the field of monitoring equipment, and specifically relates to a flow rate monitor. Background Art

[0002] The flow rate monitor is a tool for measuring open channel flow rate and flow rate in the field for hydrological stations, factories and mines, environmental monitoring stations, farmland irrigation and drainage, hydrogeological surveys and other departments. When measuring the depth, the ultrasonic transducer is placed on the water surface or at a certain position. The instrument automatically calculates the water depth H by using the fixed sound velocity VC of the ultrasonic wave in the water and the time T from ultrasonic emission to reception.

[0003] When monitoring, it is necessary to measure the river section multiple times to obtain the average value and get the instantaneous flow data.

[0004] Take the flow meters LS1206B and CS150 on the market as an example. They need to be measured manually by hand. However, for rivers with faster flow rates, due to the rapid flow of water, even if it is manually held, impact force will be applied to the measuring rod, making it impossible to keep it upright. At the same time, when the monitoring personnel move in the river, it is impossible to ensure that the measurement position is equal each time. Utility Model Content

The movable sleeve is movably connected with an adjusting ring through a damping bearing embedded in the outer ring. The adjusting ring is hinged with a support plate through an adjusting pin shaft, and an arm sleeve is fixed on the end of the support plate away from the measuring rod;

[0007] The outer ring of the movable sleeve is fixed with a nut, and the nut is threadedly connected with a positioning rod.

[0008] Furthermore, one end of the water baffle plate close to the measuring rod is a curved surface.

[0009] Through the above technical solution, when measuring, it is possible to prevent water from entering the interface between the measuring rod and the signal line and causing damage.

[0012] Furthermore, the arm sleeve is made of rubber.

[0013] Through the above technical solution, the arm sleeve has a certain elasticity and can be fixed on the arm of the monitoring personnel.

[0014] Furthermore, the adjusting pin shaft limits the rotation angle through a locking mechanism.
