Problems solved by technology

[0003] However, this method has relatively large errors in actual field operations, especially in the weather environment with strong winds and waves, the position of the transparent disk tethered by the tape measure will shift under the action of the water flow, and the actual value read on the tape measure will also be different. not allowed
[0004] Therefore, how to solve the inaccurate problem of water body transparency measurement in the prior art has become an important technical problem to be solved by those skilled in the art

Abstract

The invention discloses a measuring instrument for measuring water transparency. The measuring instrument comprises a disk, a first water pressure sensor, a wire, a second water pressure sensor, a gravity inclination sensor and a calculator, wherein the first water pressure sensor is arranged at the center of the disk; the wire is connected to the first water pressure sensor; the second water pressure sensor is connected to the wire, and a distance exists between the first water pressure sensor and the second water pressure sensor; the gravity inclination sensor is used for inducting the inclination angle of the wire; the calculator is in communication with the gravity inclination sensor, the first water pressure sensor and the second water pressure sensor. Through the arrangement, the measuring instrument for measuring the water transparency can be used for measuring the water transparency and has a high accuracy degree.

Description

technical field [0001] The invention relates to the technical field of water body analysis facilities, in particular to a measuring instrument for measuring water body transparency. Background technique [0002] At present, in field water quality measurement, transparency indicators are often obtained by traditional transparent discs, that is, black and white discs or colored discs are tied by a tape measure and sent into the water until the black and white discs or colored discs are invisible to the eyes. This is done by reading off the mark on the measuring tape. [0003] However, this method has relatively large errors in actual field operations, especially in the weather environment with strong winds and waves, the position of the transparent disk tethered by the tape measure will shift under the action of the water flow, and the actual value read on the tape measure will also be different. Not allowed. [0004] Therefore, how to solve the problem of inaccurate water t...
