Specifically, when in use, the upper liquid guide tube 21 and the lower liquid guide tube 22 are respectively connected with the upper side and the lower side of the reactor 10 for reaction, so that the liquid in the reactor 10 is led out of the reactor 10, and the liquid level (the liquid which is mutually communicated and the height of which is kept consistent) is measured outside the reactor 10 by using the liquid level measuring device 25, so that the liquid level in the reactor 10 can be accurately measured, the liquid level measuring device 25 can be prevented from being arranged in the reactor 10, and the influence of strong liquid acid (or alkali) in the reactor 10 on the liquid level measuring device 25 is avoided. Wherein the upper and lower catheters 22 communicate with the monitoring tube 23 so that the air pressure can be balanced.

In this embodiment, a pressure detecting device 24 is also included, the pressure detecting device 24 being in communication with the lower catheter 22.

Which can give a reminder when the liquid level is too low or too high.

The liquid level measuring device 25 in this embodiment is a radar level gauge. In particular, the level measuring device 25 thus does not need to be in contact with the liquid for measurement.
