|When a Wisconsin municipality needed reliable level measurement of their most challenging sewer lift stations, they turned to Flowline. Some of their pump stations have in-flow pipes located near the bottom of the sumps that pour into shallow vaults. Where so, the operators maintain the level inside the vault space to eliminate the chance of sewage back flow. But the vaults are so small, they quickly fill with grease and debris that clogs the float level switches, and requires weekly maintenance. For this reason, Flowline suggested the use of our pulse radar sensors that are unaffected by sewer grease, debris or foam, and are intrinsically safe for environments with methane gas. The radar sensor provides reliable level data to the SCADA, which in turn, controls the pumping process and alarms. The sensor’s level indicator is installed above grade in the control panel. Flowline is reliable level measurement.
