Sewerage lift stations, dry wells, and wet wells are used to transport wastewater from a low elevation, to a high elevation and are primarily used to move sewage from residential areas to wastewater treatment plants. They are also commonly used in conjunction with pumping stations in wastewater treatment facilities. Level measurement is used for accurate pump control, both to initiate pump high levels and to turn them off at low levels to prevent dry-running.
The Rosemount 3490 Series provide comprehensive control functionality for 4–20 mA or HART compatible transmitters, such as the Rosemount 1208 Level and Flow Transmitter. The series consist of two models that offer varying levels of control functionality depening on your specific application needs. The Rosemount 3490 Controller enables simple programming through intuative wizards for level and flow measurement to control pumps, totalize flows, log data and calculate differentials. The controller is easy-to-read and has a colored LCD display that offers a simple, intuitive and an user-centric interface.
