A remote water meter

Abstract

The invention discloses a remote water meter and relates to the technical field of meters. The remote water meter comprises a water meter body, a waterproof power generator and a rectifier tube. The waterproof power generator is arranged on an inlet pipe of the water meter body and is connected with the water meter body. The rectifier tube communicates with the inlet pipe and is provided with a screen board, a first rectifying part, a second rectifying part and a third rectifying part. The first rectifying part is in a hemisphere shape, and the spherical face faces the downstream direction ofwater flow. The first rectifying part is provided with a plurality of first through holes formed in the axial direction of a rectifying cavity. The second rectifying part is provided with a pluralityof second through holes formed in the axial direction of the rectifying cavity. The aperture ratio of the second through holes to the first through holes is 1:3-8. The third rectifying part comprisesa center shaft and further comprises a first guide plate, a second guide plate and a third guide plate which are connected to the center shaft. The end portions of the first guide plate, the second guide plate and the third guide plate abut against the second rectifying part, and the length ratio of the first guide plate, the second guide plate to the third guide plate is 1:1.3-1.8:2-2.5. Self-power supply can be achieved, and an external power source is not needed.

Description

technical field [0001] The invention relates to the technical field of instruments, in particular to a remote water meter. Background technique [0002] Most of the existing remote water meters need to use electric energy to support their electronic circuits and remote transmission. The current remote water meters usually use batteries as power sources, but with the further expansion of water meter functions, it has undertaken more For information collection and communication work, the power consumption also increases. In order to prolong the power supply time, high-energy batteries are usually used to prolong the battery life, but after all, the battery life is limited, and people often need to replace the remote transmission regularly The battery in the water meter brings great inconvenience to the use. Contents of the invention [0003] The first object of the present invention is to provide a remote water meter, which can realize self-power supply without providing ex...
