The present invention relates to a liquid type flow rate display device for a wet type water meter. A flow rate display unit interworking with a deceleration gear unit in a sealed housing is liquid sealed by a liquid seal medium. So, tap water does not flow into the flow rate display unit, and, therefore, a breakdown due to the inflow of the tap water is prevented. Also, the flow rate can be accurately displayed. A first row of a number dial capable of interworking with the deceleration gear unit is installed inside, and the sealed housing is connected to the lower part of a display of a main body frame by an independent component, wherein the sealed housing is liquid-sealed as the liquid seal medium is injected through an inlet on one side. So, watertight charging and an assembly process of the liquid seal medium can be rapidly and easily performed. According to the present invention, the liquid type flow rate display device for a wet type water meter, displaying the flow rate by interworking with deceleration rotation of the deceleration gear unit, includes: the main body frame installed in the upper part of the deceleration gear unit and having the display; the sealed housing connected to the lower part of the display of the main frame and including the inlet on one side, wherein the inlet can be closed; the flow rate display unit installed in the sealed housing and displaying the flow rate as the first row of the number dial rotates, by interworking with the deceleration gear unit; and the liquid seal medium sealing the sealed housing by being filled in the sealed housing including the flow rate display unit through the inlet. |
