SubSonic® Dual Pressure & Ultrasonic Level Sensor

The SubSonic Dual Pressure & Ultrasonic Level Sensor is a dual-sensor level monitoring solution that combines ultrasonic precision with pressure-based depth sensing. Engineered to operate in harsh, wet and corrosive conditions, SubSonic maintains accurate, uninterrupted measurement—even during surcharges or flooding.

Uninterrupted Sewer Monitoring

The SubSonic Dual Pressure & Ultrasonic Level Sensor delivers full visibility from the bottom of the channel to the top of the manhole. When surcharges occur, most level sensors fail—but SubSonic keeps recording. Its patented dual-sensing design seamlessly switches between ultrasonic and pressure modes, capturing data beyond the submersion point.

A low-profile design allows for installation closer to the invert, detecting even subtle changes in flow. Reliable data collection, even during rain events, high-flow conditions and power outages helps utilities make better decisions and avoid unnecessary site visits.

Features

  • Dual-Sensor Accuracy. Both ultrasonic and pressure readings to help maintain uninterrupted data—even during surcharges, flooding or when fully submerged.
  • Full-Range Visibility. Measure from the bottom of the channel to the manhole cover, to capture the full dynamic range of the system.
  • Compact, Invert-Level Placement. Detect small variations in flow level with installation low in the structure, making the sensor ideal for narrow or shallow inverts.
  • Low-Maintenance Durability. The sealed, submersible design withstands corrosive, humid environments with minimal maintenance required.
  • Applications Versatility. Installation options include wet wells, holding tanks, cable vaults, open channels and other non-sewer applications.

Market Applications

  • Collection System Monitoring

    Collection system monitoring plays a vital role in the water cycle, overseeing the movement of wastewater from its source through collection networks for treatment and disposal. Extreme weather events, fats, oils, and grease (FOG) blockages, and increased inflow and infiltration (I&I) can result in sewer spills or overflow events—endangering our environment and communities, costing utilities millions in cleanup costs. By monitoring these systems in near real-time, utilities can promptly identify and address issues for efficient operation and prevent environmental contamination.
