  • Page 5: Introduction

    Micronics Portaflow 222 & 333 User Manual INTRODUCTION General Description The Portaflow range of portable flow meters uses clamp-on transducers to enable the flow of a liquid within a closed pipe to be measured accurately without needing to insert any mechanical parts through the pipe wall or protrude into the flow system.

  • Page 6: How Does It Work

    Portaflow 222 & 333 User Manual Micronics How Does It Work? Portaflow flow meters use a cross correlation transit time algorithm to provide accurate flow measurements. An ultrasonic beam of a given frequency is generated by applying a repetitive voltage pulse to the transducer crystals.

    Micronics Portaflow 222 & 333 User Manual INSTALLATION Positioning the Transducers For accurate measurements, the transducers must be installed at a position where the fluid flows uniformly. Flow profile distortions can result from upstream disturbance such as bends, tees, valves, pumps and other similar obstructions.
