Q-Eye M II

portable Pulse-Doppler system 

 

 

For sewage treatment plants flow 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 measurements on sewage-treatment plants can therefore influence their operation, but there can also be legal or environmental consequences.
