Description

1. Technical field:

[0001] The invention relates to a liquid level display technology, in particular to a liquid level control display instrument and a usage method. 2. Background technology:

[0002] At present, people use a variety of liquid level display technologies, such as floating ball display, hydraulic pressure or resistance display. These technologies facilitate people's work from different aspects, but there are also some problems. They all use electricity to display. Displaying the liquid level has the disadvantages of high cost, short maintenance life and great potential safety hazards. 3. Contents of the invention:

[0003] The purpose of the present invention is to provide a liquid level control indicator and its use method which can not only display the liquid level but also control and adjust the liquid level, has a simple structure and low cost, and it overcomes the shortcomings of other technologies. It is realized by meter head, fixed frame, meter head...
