- Introduction
The CONVA LDGR remote water flow meter is a device used to measure the flow rate of water in a pipeline or other water system. This type of meter is designed to be installed at a distance from the point of measurement, allowing for remote monitoring of water usage and flow rates.
Remote water flow meters are commonly used in industrial and commercial applications, where accurate measurement of water usage is important for billing and other purposes. They can also be used in residential settings to monitor water usage and identify leaks or other issues.
One of the key benefits of a remote water flow meter is that it allows for real-time monitoring of water usage. This can help to identify leaks or other issues early on, allowing for prompt repairs and reducing the risk of water damage or other problems.
Another advantage of remote water flow meters is that they can be integrated with other systems, such as building automation systems or water management software. This allows for more efficient management of water usage, as well as improved tracking and reporting of water consumption.
When selecting a remote water flow meter, it is important to consider factors such as accuracy, reliability, and ease of installation. It is also important to choose a meter that is compatible with the specific type of water system being monitored.

- Measuring principle
Mag meter works based on Faraday’s law, and measure conductive medium with conductivity more than 5 μs/cm and flow range from 0.2 to 15 m/s. An Electromagnetic Flowmeter is a volumetric Flowmeter that measures the flow velocity of a liquid through a pipe.?
The measurement principle of magnetic flow meters can be described as follows: when the liquid goes through the pipe at the flow rate of v with a diameter D, within which a magnetic flux density of B is created by an exciting coil, the following electromotive E is generated in proportion to flow speed v:
