When the cutoff probe detects that the liquid in the main pipeline 5 is cutoff, the cutoff probe sends a signal to the operation control terminal 10, and the operation control terminal 10 gives an alarm to remind a worker to timely handle the cutoff condition.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
