Description

Water leak sensor module

The present invention relates to a water leak sensor module.

Remote meter reading involves connecting a wireless data transmission/reception device to a meter to measure the amount of fluid used, such as water or gas, from a distance.

This remote meter reading improves the problem of meter reading on the same day every month, reducing the time required for meter reading and labor costs. At the same time, accumulated data can be used in the field of demand forecasting, such as expansion or reduction of pipes, and the measured data As equipment with improved accuracy is proposed, its utilization is gradually expanding.

However, in remote meter reading, there is a difference between the flow rate supplied from the supplier and the flow rate metered at the point of use. There are several causes for this difference, the main causes of which are water leakage due to the rupture of the pipe connecting the supply and use points, and water leakage due to the flange connecting the two pipes.

Therefore, it is beneficial to both the supplier and the user to accurately identify the point where leakage occurs in the pipe and the leakage flow rate. As the leakage flow rate increases, ground subsidence may occur, which may lead to a major accident or require large-scale replacement work. .

Currently, technologies that can detect leaks in pipes include acoustic detection and correlation detection. Additionally, technologies for measuring leakage flow include electrical resistance and ultrasonic flow/velocity meters.

Here, the correlation detection method installs two water leak sensors on both sides of the pipe, and when a water leak vibration sound wave occurs at a water leak point in the pipe, the water leak vibration sound wave reaching each of the two water leak sensors from the water leak point in the pipe is measured. The point of leakage in the pipe is calculated through the time difference.

In the conventional water leak detection device using this correlation detection method, the fixing unit that fixes the water leak sensor to the pipe or measurement pipe is a magnetic material, so if the material of the pipe or measurement pipe is a material that cannot be magnetically coupled, such as non-metal, water leakage occurs. There was a problem that it was impossible to fix the sensor.

Additionally, in the prior art, the flow meter and water leak sensor were separately configured, making installation inconvenient and maintenance difficult.

In addition, in the prior art, as the flow meter and water leak sensor operate separately, batteries and antennas for each flow meter and water leak sensor were required. As a result, there was a problem in that the size of the flow meter and water leak sensor increased.

The present invention was created to solve the above-mentioned problems, and the purpose of the present invention is to detect water leaks by easily mounting a water leak sensor on existing pipes or existing measuring systems, regardless of the material of the existing pipes or existing measuring systems. The purpose is to provide a water leak sensor module that can
