How many flow meters are typically present in an RO plant?

In a reverse osmosis (RO) plant, having two flow meters is common practice for effectively monitoring and controlling the system. Typically, one flow meter is installed on the feed water line to measure the incoming flow rate of the water that is being processed. The second flow meter is often located on the permeate line, measuring the flow rate of the purified water being produced by the RO system.

This setup allows operators to gain an accurate understanding of both the input and output of the RO process, ensuring that the system is functioning efficiently. It also helps in troubleshooting by providing critical data about water usage and production levels, which is essential for optimizing performance and managing any potential issues that arise during operation.
