Water & Wastewater Instrumentation Solutions

Foam can disrupt ultrasonic sensors by absorbing the signal. For aeration tanks with heavy foam, radar level transmitters (specifically 80GHz high-frequency radar) or hydrostatic pressure sensors are recommended as they are unaffected by foam layers and provide stable measurements.

Optical DO sensors use fluorescence quenching technology, requiring no electrolyte replacement, no warm-up time, and minimal drift, making them lower maintenance than traditional electrochemical (membrane-based) sensors, which require regular electrolyte refills and calibration.

Yes, clamp-on ultrasonic flow meters are the ideal solution for large pipes or retrofitting existing lines. They install on the outside of the pipe, requiring no downtime or cutting, and are suitable for clean water or wastewater with minimal solids.

Using a flush diaphragm seal or an isolation diaphragm prevents viscous sludge from entering the sensor cavity. Alternatively, a "hammer union" style or a sensor with a wide, open port is designed specifically to handle viscous media without clogging.

Regular cleaning is critical to remove biofilm or scale buildup on the glass bulb. Using an automatic cleaning system (air or water jet) can significantly reduce manual maintenance. Additionally, periodic calibration with buffer solutions ensures accuracy as the sensor ages.

Fluctuations often result from partially filled pipes, air bubbles, or poor grounding. Ensure the sensor is installed at a low point in the piping (or a vertical rising pipe) to guarantee a full pipe, and verify that proper grounding rings or straps are installed to eliminate electrical noise.

Yes. Aggressive chemicals like ferric chloride can corrode standard materials. For chemical dosing, use an electromagnetic flow meter with a PTFE (Teflon) or PFA liner and Tantalum or Platinum electrodes to ensure long-term chemical resistance.
