Abstract
The utility model relates to an electronic display device for the water level. The utility model is mainly composed of a voltage stabilizing circuit, a water level switch circuit, and a water-level display circuit. The utility model has the advantages of simple structure, small volume, stable operation, low manufacture cost, convenient use, convenient maintenance, idealization, practicality, etc.
Description
The utility model relates to a kind of level displaying device.Level displaying device commonly used is gone up by society at present U type glass tube level displaying device.But, have the limitation of visual line of sight in the use, and the utility model has overcome the limitation of sight line, be that comparatively ideal level displaying device is gone up by society at present.
Task of the present utility model be to provide a kind of simple in structure, volume is little, working stability, low cost of manufacture, easy to use, be convenient to keep in repair, desirable practical novel level displaying device.
