Abstract

The invention discloses a fluid level gage applied to high pressure boiler. The fluid level gage includes a connector connected to the measured container, the connector has a magnetic float elevating with the fluid level, the external side of the connector has a vernier coupled with the magnetic float, several photoelectric switches are arranged on the measured container with the fluid height, the vernier corresponds to different photoelectric switch when it is in different height, thus it is shaded and reflected; each photoelectric switch is connected to the control unit, it outputs voltage different to other photoelectric switch according to the voltage of the photoelectric switch, acquires the fluid height of the measured container. The device in the invention can provide fluid level electric signal output.

Description

Technical field:

[0001] The present invention relates to liquid level gauges, especially liquid level gauges that indicate liquid level by means of floats. Background technique:

[0002] For decades, boiler manufacturers in my country have used boiler water level gauges with two pieces of glass tightly joined together and fastened with bolts. The operation is not easy to distinguish, and the water level gauge is also easily polluted by water quality, which affects the observation effect. Moreover, dripping often occurs and requires frequent maintenance. , especially not suitable for high-pressure boilers. The Chinese Utility Model Patent No. 97213186.8 discloses a magnetic tracking color plate liquid level gauge, which is characterized in that the connector of the measured container is fixed on the outside of the measured container, and there is a magnetic float inside the connector that rises and falls with the liquid level , There is a magnetic color code coupled with the ...
