[0002] A liquid level meter is an instrument used to measure the height of a liquid medium in a container. Its main function is to monitor and control the liquid in the container to ensure that the liquid does not exceed or fall below the safe operating level, thereby avoiding dangerous situations such as overflow or dry burning. The main types of liquid level meters currently include float level gauges, magnetic flap level gauges, and radar level gauges.

[0003] The working principle of the float level gauge is that the float moves up and down with the rise and fall of the liquid level, and the position change of the float is converted into an indication of the liquid level through a mechanical device. Most of the current float level gauges are independent single level gauge detections. For containers with multiple control points at different heights, they need to be installed in multiple positions on the container, and holes need to be drilled in the container each time for installation. The installation also requires emptying the liquid in the container, which makes installation difficult and prone to leakage. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a liquid level gauge for an RO heating and filtering device, which solves the limitations of single liquid level gauge detection, the need to install multiple independent liquid level gauges for multiple control points, the difficulty in installing the liquid level gauge and the easy damage and leakage of the container, and the need to empty the liquid in the container during installation.

[0006] Preferably, a plurality of the limit blocks are spirally connected with a No. 1 bolt, and the positioning block is connected with a No. 2 bolt.

[0007] Preferably, the limit block is fixed to and separated from the stainless steel pipe by rotating a No. 1 bolt, and the positioning block is fixed to and separated from the stainless steel pipe by rotating a No. 2 bolt.

[0009] Preferably, the limit block, float and positioning block form a liquid level control range, and there are multiple limit blocks, floats and positioning blocks on the stainless steel pipe, forming multiple liquid level control ranges, which is convenient for multi-liquid level detection.

[0010] Preferably, the liquid level control range can be adjusted by adjusting the positions of the limit block and the positioning block, thereby reducing related installation operations.

[0011] Preferably, the No. 1 protection pad and the No. 2 protection pad are made of corrosion-resistant materials.
