- For sewage treatment plants [flow rate] measurements are primarily installed for internal reasons, for example to control specific plant components with flow dependency or for controlling additives. International regulations for example the EU-Directive for handling municipal waste water require a continuous surveillance of waste water flow. Defective flow [flow rate] measurements on sewage-treatment plants can therefore influence their operation, but there can also be legal or environmental consequences.
