VOLUME FLOW MEASURING ELEMENT - ULTRASONIC DOPPLER

A class with identifier http://staging4.data.posccaesar.org/iso/15926-4/rdl/RDS1009799

MetadataThis section provides information about 'RDS1009799'.

DefinitionA <VOLUME FLOW MEASURING ELEMENT - ULTRASONIC DOPPLER> is a <VOLUME FLOW MEASURING ELEMENT - VELOCITY> that measures the Doppler shift resulting from reflecting an ultrasonic beam off the particulates in flowing fluid. The frequency of the transmitted beam is affected by the movement of the particles; this frequency shift can be used to calculate the fluid velocity. For the Doppler principle to work there must be a high enough density of sonically reflective materials such as solid particles or air bubbles suspended in the fluid
ISO number4345
NoteThe doppler flow meter operates by transmitting an ultrasonic sound from its transmitting transducer through the pipe wall into the flowing liquid. The sound will be reflected by the reflectors and recorded by the receiving transducer.
