## Abstract

An improved water meter has a meter body with an extended bottom on the periphery of which are disposed a plurality of spaced first oval holes and at the center of the meter is disposed a small round hole. To the bottom of the water meter is journalled a cone-shaped block. A round cavity is disposed at the center of the block with a plurality of spaced first oval holes defined on the periphery thereof that communicate respectively with a plurality of tilted slots on the bottom periphery of the block. A vertical mounting post is disposed at the center of the cavity. A rotation propeller having a plurality of blades and a driving shaft is engaged with the small round hole with its driving shaft and engaged with the vertical mounting shaft at the bottom end. The cone-shaped block and the water meter are journalled together with the rotation propeller housed therebetween. The assembled water meter is received in a housing cavity having a vertical water inlet duct and an elbow water outlet duct connected to a check valve.

## Claims

### Claim 1

An improved vertical water meter, comprising:
a meter body having an extended bottom portion and a plurality of spaced first oval holes at one end thereof;
a rotation propeller;
a cone-shaped block having a central cavity;
a housing cavity having a vertical water inlet duct and a horizontal water outlet duct;
an elbow tube connected to said horizontal water outlet duct;
a check valve being connected to said elbow tube;
a removable tube being connected to said vertical water inlet duct;
a ball valve being connected to said vertical water inlet duct;
said rotation propeller having an extended driving shaft and a plurality of spaced blades;
said cone-shaped block being provided with a mounting post at the center of said central cavity; and a plurality of spaced second oval holes on the periphery of said central cavity; a plurality of spaced slots disposed at the end of said cone-shaped block;
a round hole being disposed at the center of said extended bottom portion and engaged with one end of said driving shaft;
said rotation propeller being mounted to said mounting post at one end and engaged with said round hole at the other;
said rotation propeller being housed between said meter body and said central cavity of said cone-shaped block;
said cone-shaped block and said meter body being received in said housing cavity;
whereby water led into said vertical inlet duct and further into said cone-shaped block via said slots and said second oval holes and discharged out thereof via said spaced first oval holes at one end of said meter body.
