[0036] A float-type level gauge with remote transmission capability. The most prominent feature of this technical solution is that all components can be purchased and assembled individually.

[0037] In the level gauge assembly, the float-type level gauge includes: a three-way connector 4, a first pipeline, and a second transparent pipeline 12;

[0038] One end of the first pipeline is connected to the first port of the tee connector 4;

[0039] The other end of the first pipeline is connected to a first valve 1, which is used to connect to the liquid storage tank;

[0040] The lower end of the second transparent pipe 12 is connected to the second port of the three-way connector 4, and the upper end of the second transparent pipe 12 is used to communicate with the liquid storage tank, and the communication point is located above the liquid surface of the liquid storage tank.

[0041] A float 11 is installed inside the second transparent pipe 12, and a scale is marked on the outer wall of the second transparent pipe 12 for reading the volume or level of the liquid in the storage tank. In this application, a small plastic ball can be used as the float.

[0042] The third port of the tee connector 4 is connected to a pressure sensor 7. The pressure sensor 7 is used to connect to an external system. The pressure sensor 7 can convert the volume or level of the liquid in the storage tank into pressure to display the volume or level of the liquid in the storage tank.

[0043] The second transparent conduit 12 is perpendicular to the first conduit. The third port and the first port of the tee connector 4 are parallel to each other.

[0044] Specifically, the first pipeline at the bottom of the float-type level gauge is connected to the liquid in the storage tank via the first flange 2 and the first valve 1 via the first fastener 14. To prevent liquid leakage, the first flange 2 and the first valve 1, and the first valve 1 and the storage tank flange are sealed with the first gasket 3.

[0045] On the first pipeline connected to the first flange 2, a tee fitting 4 divides the liquid flow into two paths. One path connects to the pressure sensor 7 via the second valve 5. The pressure sensor 7 is used to transmit pressure signals remotely. To facilitate the installation of the pressure sensor 7, an internal threaded manifold 6 is installed on the second valve 5 for easy sensor replacement. The second valve 5 is used to close the liquid path branch when replacing the pressure sensor 7 to prevent liquid leakage.

[0046] The second port of the tee connector 4 is connected to the transparent pipe 12. The second transparent pipe 12 has a built-in float 11, which uses the principle of communicating vessels to detect the liquid level. At the same time, a scale is marked on the transparent pipe 12, and the volume or liquid level of the liquid in the storage tank can be read through the scale.

[0047] The upper end of the second transparent pipe 12 is connected to the liquid storage tank connecting pipe 13 via an elbow 8. The liquid storage tank connecting pipe 13 is connected to the liquid storage tank flange via a second flange 9 and a second fastener 15. A second gasket 10 is used to seal the second flange 9 to the liquid storage tank. The second flange 9 is connected to the upper part of the liquid storage tank, and its position should be located above the liquid in the liquid storage tank.

[0048] In this application, except for the first fastener 14 and the second fastener 15, the remaining floats, valves, pipe fittings, etc., are all made of plastic, which can effectively provide corrosion resistance and insulation. Therefore, this float-type level gauge can be used in acidic and alkaline environments and in flow battery energy storage systems.
