Step 5, magnetic-float type liquid level gauge full scale adjustment：Pass through magnetic-float type liquid level described in the injection valve goalkeeper
Surveyed medium is filled in meter, the universal meter is shown as 20mA；
Step 6, magnetic float liquidlevel meter preparation come into operation：The injection valve is closed, the sewage draining valve is opened and arranges surveyed medium
It is closed after removing, opens the first conveying valve and the second conveying valve, the universal meter displays whether exception.
7. a kind of magnetic-float type level gauge detection method as claimed in claim 6, it is characterised in that：The universal meter is shown
When being shown with abnormal, repeat the above steps 4 and step 5.
