The fluid level gauge of claim 1, wherein the gauge head electrical connector and the sensing portion electrical connector include a guide structure to guide the connection of the gauge head electrical connector and the sensing portion electrical connector when the gauge head electrical connector and the sensing portion electrical connector are removably connected.

10. The fluid level gauge of claim 9, wherein the guide structure comprises a first plug of the meter head portion electronic connector and a second plug of the detection portion electronic connector, the first plug and the second plug being hollow in shape, and an inner diameter of the first plug is greater than or equal to an outer diameter of the second plug or an inner diameter of the second plug is greater than or equal to an outer diameter of the first plug.

11. The liquid level gauge as claimed in claim 9, wherein the head portion electronic connecting member and the sensing portion electronic connecting member are provided with an electrical connecting structure, the electrical connecting structure of the head portion electronic connecting member is pin-shaped or hole-shaped and the sensing portion electronic connecting member is hole-shaped or pin-shaped, so that the pin-shaped structure can be inserted into the hole-shaped structure when the head portion electronic connecting member is connected to the sensing portion electronic connecting member.

12. The gauge of claim 1, wherein the gauge is a magnetostrictive, radar or capacitive gauge for measuring an object to be measured.
