## Title
Pipe connection having a flow counting function

## Abstract

A pipe connection includes a main body, an inner sleeve, a water inlet connector, a water outlet connector, a circuit board, a control panel, at least one battery, a magnetically activated detector, an impeller, and a magnetic member. In operation, when the water flows through the impeller, the impeller is rotated, and the magnetic member is moved to pass by the detector intermittently so that the detector can transmit a detected signal to the circuit board which can calculate the rotation speed of the magnetic member so as to obtain the water flow rate. Thus, the pipe connection can calculate and indicate the water flow rate in the pipe so that when the flow rate of the output water from the pipe reaches a preset value, the user can shut the water flow to regulate and save the water flow.

## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a connecting device and, more particularly, to a pipe connection to connect two water pipes.
2. Description of the Related Art
A conventional pipe connection has a first end connected with a first pipe which is connected with a water source, such as a faucet and the like, and has a second end connected with a second pipe which is connected with a water outlet device, such as a sprinkler, sprayer and the like. Thus, water from the first pipe in turn flows through the pipe connection into the second pipe and is injected outward from the water outlet device for use with a user. However, the conventional pipe connection cannot calculate the water flow rate in the pipe so that the user cannot regulate water flow exactly, thereby easily consuming the water resource.

The main body 10 has an open top side formed with a receiving space 14 to receive the circuit board 23 and an open bottom side formed with a receiving recess 15 to receive the battery 151.
The electric wire 152 extends from the receiving recess 15 of the main body 10 to the receiving space 14 of the main body 10.
The circuit board 23 is received in the receiving space 14 of the main body 10 and is located between the inner sleeve 11 and the control panel 20. The circuit board 23 has a surface provided with a display 231 and a control switch 232.

The water outlet connector 40 is mounted on the mounting portion 131 of the inner sleeve 11.
The water inlet connector 30 is partially received in the receiving chamber 12 of the inner sleeve 11 and has an end portion having a periphery formed with a plurality of connecting bores 311 and having a central portion formed with a shaft bore 31. The water inlet connector 30 has a peripheral wall provided with a locking portion 33.
