This paper concerns the pressure losses involved in measuring flow rate. These losses can be large and affect the choice of pump or flow metering section to be used. Solutions are developed for predicting these losses for various fluid meter arrangements. Several methods are described for reducing fluid meter loss, including the use of a new step diffuser. Experimental results are given which verify the theoretical solutions. Design curves are presented to aid in the optimum choice of the flow metering section.
