  • Page 5: 1: General Description

    The Portaflow 220 series comprises two models which are identical in operation but designed to be used with a different range of pipe diameters. The PF220A can be used with pipes in the range 13mm – 115mm and the PF220B with pipes in the range 50mm –...

  • Page 6: Principles Of Operation

    The Portaflow 220 system employs two ultrasonic transducers attached to the pipe carrying the liquid and compares the time taken to transmit an ultrasound signal in each direction. If the sound characteristics of the fluid are known, the Portaflow microprocessor can use the results of the transit time calculations to compute the fluid flow velocity.

    5 diameters downstream, but when the transducers are positioned this close to any obstruction the resulting errors can be unpredictable. Key Point: Do not expect to obtain accurate results if the transducers are positioned close to any obstructions that distort the uniformity of the flow profile. Portaflow 220 User Manual (Issue 1.0)
