What should be done if the liquid level gauge of the medium-pressure drum fails suddenly in winter? Answer: (1) Contact the instrumentation workshop immediately and arrange for someone to handle it as soon as possible ； ⑵The shift supervisor on site immediately corrected the liquid level gauges of the two medium-pressure steam drums at the site ； ⑶Maintain the upstream flow rate and production load at their levels prior to instrument failure ； ⑷People are sent to the site in shifts to monitor the level gauge.

Step 1: Determine whether the operating conditions are abnormal; if there is no change, first disconnect the interlock, and then refer to the above four points!
There is more than one level gauge; if such a level gauge is equipped with interlocks, it is necessary to bypass it immediately and reset it so that normal operation can be resumed. By \"normal operation\" is meant the valve settings that existed before the problem occurred. The drum liquid levels I’ve used are at least 4 in number, along with at least 3 level switches; in half of these cases there won’t be any major problems, so just handle it calmly. Verify with the on-site level gauge. In addition to the level gauge freezing, another situation is that the float type buoy loses its magnetism due to high temperatures. The most reliable method is to wait on site. If it’s a freezing issue, then those things should be prepared before winter to avoid freezing.
