Claims

[Claims for Utility Model Registration] 1. A casing that is fixed in a tank in which a fluid is stored and allows the fluid to flow freely; a float that is housed in the casing and floats and sinks as the fluid level changes; A fluid level detection device comprising electrical contacts respectively disposed on the casing and the float, the casing side contact and the float side contact forming an electric signal when they come into contact with each other to warn of a decrease in fluid in the tank. The fluid level detection device according to the invention, wherein the casing has a recess near the center of the bottom thereof, and a sphere that cannot be floated by the fluid is disposed in the recess. 2. Utility Model Registration Scope of Claim 1. The fluid level detection device according to claim 1, wherein the casing has a longitudinal guide means that extends toward the bottom and guides the float. 3 Utility Model Registration The fluid level detection device according to claim 2, wherein the guide means extends toward the recess in the bottom of the casing. 4 Utility Model Registration Scope of Claim 1 The device according to claim 1 is characterized in that the alarm is provided with a timer and is generated only when the casing side contact and the float side contact are in contact with each other for a certain period of time or more. Fluid level detection device.
