UltraFlo™ UFDD Digital Doppler Clamp-On Flow Meter

UltraFlo™ UFDD Digital Doppler Clamp-On Flow Meter

The UltraFlo™ UFDD Clamp-On Ultrasonic Flow Meter is the ideal flow meter with accurate, easy-to-use, easy-to-install digital doppler technology. The UltraFlo™ UFDD is offered in a portable flow meter design or permanent mount installation.

Both are extremely rugged, reliable and durable. The flow meters are housed in a NEMA 4X fully sealed enclosure to withstand the most severe conditions.

The patented Digital Doppler technology will measure just about any liquid or fluid from potable water to 30% thickened sludge and fly ash slurries. The easy to read LCD alpha-numeric display, versatile   AC & DC power operation, digital communications, batch control and data log events are all packaged in an affordable industrial design.

Because the UltraFlo™ UFDD sensors are clamped onto the outside of the pipe, the installation costs   are a fraction of installed costs of traditional in-line flow meters.

Plus, the sensors and electronics are immune to the process conditions regardless of process pressures, temperatures and build-up or scaling conditions. The Digital Doppler transducers will mount to just about any size pipe regardless of pipe wall thickness.
