It is additionally provided with in described PCB 23 and indicates the power supply indicator 25 whether level monitoring device switches on power, continue
Electrical equipment (not shown), power-off holding capacitor (not shown), and binding post.When the liquid level in testing container from down to up
When slowly raising, ball float 13 increases, and the magnetic reed switch 16 of 13 processes of ball float closes, and produces switching signal, integrated package
22 detect this signal, under the effect of relay, open corresponding liquid level display lamp 24.When liquid level declines, ball float 13 is passed through
Magnetic reed switch 16 close, produce switching signal, integrated package 22 detection can arrive this signal, under the effect of relay, closedown
Corresponding liquid level display lamp 24.Liquid level display lamp 24 signal can also be drawn by the binding post on integrated package 22, concentrates
Control.In the event of a power failure, the power-off holding capacitor in integrated package 22, keep level monitoring device normally to work, it is achieved
To the level monitoring in current testing container.
As shown in Figure 6, when monitoring the liquid level in testing container, by the mounting flange in rosette 11, by whole device
Monitoring means 1 be arranged on testing container.Integrating control unit 2, by PVC flanged plate thereon, is fixed on and can conveniently observe
Place.Integrating control unit 2 is connected with the rosette 11 on monitoring means 1 by cable.During monitoring, integrating control unit
2 connect external power supply, and power supply indicator 25 can be pointed out whole device to have been turned on power supply, can normally be worked.Now, to testing container
Middle adding liquid, the liquid level change in container can cause ball float 13 to move up and down on the first protection sleeve pipe 12, the first protection set
Magnetic reed switch 16 in pipe 12, under Magnetitum 17 effect in ball float 13, can close.When closing every time, integrating control unit 2
Integrated package 22 all can remember corresponding process, when liquid level rises, opens corresponding liquid level display lamp 24, when liquid level declines, closes
Close corresponding liquid level display lamp 24.Because only that a ball float 13, so only meeting the liquid level of condition, phase just can be opened
The liquid level display lamp 24 answered.As shown in Figure 6A, when the actual liquid level in testing container is between L and H, all of magnetic reed switch
16 do not close, and under the control of integrated package 22, corresponding liquid level display lamp 24 LL and L opens.During such as Fig. 6 B, when to be measured
Actual liquid level in container is when H, and now the magnetic reed switch 16 of H position is Guan Bi, and remaining magnetic reed switch 16 does not closes,
Under the control of integrated package 22, corresponding liquid level display lamp 24 H, L and LL open.During such as Fig. 6 C, when the reality in testing container
When border liquid level is between H and HH, all of magnetic reed switch 16 does not closes, under the control of integrated package 22, and corresponding liquid
Display lamp 24 HH, L and LL open in position.
Level monitoring device described in the utility model, by arranging several magnetic reed switch in the first protection sleeve pipe 12
16, on integrating control unit 2 under the effect of relay, the ball float 13 setting Magnetitum 17 in only needing can complete liquid level prison
Survey, and the liquid level in current testing container is shown by LED liquid level display lamp 24, effectively reduce cost.With
Time, the first protection sleeve pipe 12 uses PP pipe to make, the advantage with corrosion resistance.
Technology contents of the present utility model and technical characteristic have revealed that as above, but those of ordinary skill in the art still may be used
All replacements without departing substantially from this utility model spirit and modification can be made based on teaching of the present utility model and announcement, therefore, this
Utility model protection scope should be not limited to the content disclosed in embodiment, and should include various without departing substantially from replacement of the present utility model
And modify, and contained by present patent application claim.
