Photometer 9 is started to work, and water sample is promoted to by sample feeding pipe 5 in gauge line 1, when water sample passes through interior photometer 9 in gauge line 1
When monitoring reaches 1000ML, motor 4 is stopped, while sampling the closing of control valve 6, and entire sampling work is completed；Start at this time
Simultaneously timing is stood, when the sedimentation time reaches 30 minutes, outer photometer 10 is started to work passes to control device 11 by photometric signal
And it is shown in digital form on liquid crystal display 12.After being measured, system can automatically empty water sample in gauge line 1.Row
Sample control valve 8 is opened, and motor 4 drives the rotation of screw rod 3 to push cock 2, and water sample under pressure, passes through 7 row of nesting tube
Go out.It can be arranged by control device 11 according to reality and stand the reading duration.
Above-mentioned sludge settling ratio online auto monitoring device, structure novel, high degree of automation can be sampled according to setting
Frequency carries out automatic sampling and reads, and measurement data can be transmitted to middle control monitoring system, measures accurately, and being capable of long-term preservation.
