246.Brass manifolds for central heating system

When installing central heating systems with riser distribution manifolds, making relevant connections with the hydraulic separator and working with condensation boilers, the corrosion of steel elements is a common problem, making the flow meters installed on the radiant panel manifolds illegible.
We know that anti-corrosion additives remain stable only for a certain period of time, after which they may worsen the situation if the system is not rapidly cleaned. Is there any possible alternative remedy?
