Claims

[Scope of utility model registration request]

(1) A float that follows water level fluctuations and a recess on the outer surface.
a rope having a convex portion and one end connected to the float; a wheel over which the rope is stretched so as to hang the float; and a wheel having a groove portion on its outer peripheral surface that engages with the uneven portion of the rope; and a balance means for applying a force to the float to pull up the float with a force equal to the value obtained by subtracting the buoyancy from the weight of the float, and detecting the water level from the rotation angle of the wheel. .

(2) A request for registration of a utility model characterized in that the rope having irregularities on its outer circumferential surface is made by winding and fixing a relatively small diameter single or double wire in a spiral around the outer circumference of a relatively large diameter core wire. The water level gauge described in item 1.

(3) The water level gauge according to claim 1, characterized in that the rope having an uneven portion on its outer circumferential surface has protrusions on the outer circumference of a core wire.

(4) The water level gauge according to claim 1 of the utility model registration, characterized in that the rope having an uneven portion on its outer circumferential surface has a groove provided on the outer circumference of a core wire.

(5) The water level gauge according to claim 1, wherein the balancing means includes a weight.

(6) The water level gauge according to claim 1, wherein the balance means includes a constant output spring.
