Sump Level Measurement
Level measurement in sump and pump control are often a maintenance challenge. Historically, floats, bubblers, ultrasonic, and capacitive probes were used to provide level control. These technologies have proven to be maintenance-intensive primarily due to buildup, plugging, and foam.
The VEGAPULS 67 radar or VEGAFLEX 81 guided wave radar provide reliable continuous level measurements. Both instruments are unaffected by viscosity and product variance. The VEGAFLEX 81 works particularly well in applications with foam.
By using more reliable technology such as radar or guided wave radar, maintenance costs are reduced significantly.
Local Pump Control
When a radar or guided wave sensor is used in conjunction with a VEGAMET 391, the system provides efficient monitoring of the process level. This decreases the risk of overfill, downstream contamination, and pump overuse.
With up to six relays, the VEGAMET 391 provides lead/lag-changeover control of the pumps, allowing the controller to maintain consistent usages throughout the system.
