Sewage Treatment Plants and Flow Sensors for Industry Application

In sewage treatment plants, flow sensors are primarily installed for internal reasons. Ultrasonic flow meters are used to control the flow velocity in partially filled and fulfilled pressurized pipes, specific plant components, for leak detection or to control the use of additives. International regulations such as the EU-Directive for handling municipal waste water require flow metering for a continuous surveillance of waste water flow. Defective flow monitoring in sewage-treatment plants can therefore influence their operation, but there can also be legal or environmental consequences.
