Embodiment 1
[0023] see Figure 1-2 , this embodiment provides a high-precision water level measuring device for a water level meter, which includes a connecting device structure arranged on one side of the furnace body 1 and formed by the first pipe body 2, the elbow joint 3 and the second pipe body 4 and the furnace body 1 The display tube 5, the side wall of the display tube 5 is provided with an observation port, the outside of the display tube 5 is provided with a second pressure gauge (not shown) for detecting the internal pressure of the display tube 5, and the viewing port is provided with a display glass 17. A first pressure gauge 16 for detecting the internal pressure of the furnace body 1 and a controller 15 electrically connected to the first pressure gauge 16 are installed on the furnace body 1, and the second pressure gauge is connected with the control The device 15 is electrically connected, and the upper part of the display tube 5 is equipped with a pressure compensation a...
Embodiment 2
[0036] see figure 1 and image 3 , a high-precision water level measuring device for a water level meter. Compared with Embodiment 1, the side wall of the furnace body 1 is also fixedly provided with a second support plate 18, and the drive shaft 6 is far away from the end of the motor 14. It is rotationally matched with the second support plate 18 through a bearing 19 .
[0037] The embodiment of the present invention has the advantages of convenient use and high measurement accuracy. The liquid level of the furnace body 1 can be measured accurately in real time according to the pressure change inside the furnace body 1. The first drive rod 8, The second drive rod 10 and the pressing plate 9 move up and down, thereby increasing or decreasing the pressure inside the display cylinder 5, so that the pressure inside the display cylinder 5 and the furnace body 1 are always equal, ensuring that the liquid level inside the display cylinder 5 is equal to that of the furnace body 1.
