Specific embodiment
For ease of description, in following embodiment, the lower end of the drinking-water pipe of so-called water-quality sampler refers to acquisition water sample
When, which enters the one end then to intake in water；On the contrary, one end that the drinking-water pipe is used to be discharged water is set as upper end.
Embodiment 1
Water level measurement method, the depth of water sampling point locating for the lower end of the drinking-water pipe for measuring water-quality sampler.Specifically
For, this method is to convert air pressure for the pressure of liquid in drinking-water pipe using a sealing tracheae, then passes through pressure sensor
The endotracheal barometric information of the sealing is collected, and after function circuit board carries out information processing, finally obtains the depth of water sampling point
Angle value.Such method is relatively simple, and can be detected at any time during drawing water, more flexibly and conveniently.This reality
The method for applying example 1 can be achieved by the device of following embodiments 2, but be not limited only to this.
Embodiment 2
As shown in connection with fig. 1, level measurement device, for measuring the drinking-water pipe 100 of water-quality sampler (being not shown on figure)
The depth of water sampling point locating for lower end, the water-quality sampler further include having peristaltic pump (being not shown on figure).
Specifically:
The measuring device includes: three-way magnetic valve 10, sealing tracheae 20, baroceptor 30, function circuit board 40, display
The components such as module 50, power module 60, conduit 70.
The three-way magnetic valve 10 includes water inlet end 11, water outlet 12, connection end 13.That is, after the three-way magnetic valve 10 work
The water inlet end 11 can be made to be connected to the water outlet 12 and the water inlet end 11 be connected to this end 13 disconnection；Alternatively, making the water inlet end
