Portable ultrasonic flowmeter
The TransPort PT868 portable ultrasonic liquid flowmeter measures flow rate through metal, plastic and concrete-lined pipes without penetrating the pipe wall. Obstructionless wetted transducers are available for maximum performance. Accuracy is typically 1 to 2 percent of reading with clamp-on, and better then 1 percent with wetted transducers. Measurement range is 0.1 to 40 ft/s for a turn-down ratio of 400-to-1 in pipes from one-half inch to more than 200 inches in diameter. Measurement is non-contaminating, obstructionless and causes no pressure drop. The PT868 is all digital so measurements don`t drift.
