Problems solved by technology

An important defect of such a detection process is its hysteresis. It is often tested only when the turbidity of the water is obviously not up to standard. At this time, it has undoubtedly caused damage to the health of the drinker.
If it is a regular detection, first of all, there is still the disadvantage of not being able to grasp the water quality in the first place; secondly, this method is a great consumption of manpower and material resources

Abstract

The invention discloses a device for detecting turbidity on line and in real time, and belongs to the technical field of turbidity detection of water quality. The device for detecting the turbidity on line and in real time comprises a water gauge in which a turbidity sensor is arranged; and the turbidity sensor comprises a photoelectric element, a photosensitive element, a driving circuit, a flowsignal sampling circuit, a receiving control circuit, a comparison circuit and a power supply. Compared with the prior art, the device has the advantages that: when water, passing through the water gauge, in a water pipe is static or has a low flow speed, the device can be used for detecting whether the turbidity of the water in the water pipe is overproof; the device is easy and convenient to use; the tested data can instantly show the water quality of the water in the water pipe; and the measurement is more accurate.

Description

technical field [0001] The invention relates to the technical field of water quality turbidity detection, in particular to an online real-time detection device for turbidity combined with water meter technology. Background technique [0002] As people's living standards are getting higher and higher, people's requirements for drinking water quality are getting higher and higher, and turbidity is an important evaluation factor reflecting water quality, but the current situation is that people often cannot simply know the status of turbidity Generally, users use their eyes to distinguish directly, but usually when the human eyes can perceive that the turbidity is not up to the standard, the water quality is already very poor, and then the turbidity detection will be carried out. The current detection method is usually in the It is carried out in the laboratory. Firstly, the water sample is taken in the water pipe and sent to the laboratory. The laboratory adopts the scattering...
