  • Flow Meter Types Based on Measurement Techniques

    Flow meter is an instrument used for the measurement of the amount of liquid, gas or vapor that passes through them In some flow meter the flow is measured as the amount of fluid passing through the flow meter during a time period (such as 100 liters per minute) whereas other flow meters measure the totalized amount of fluid that has passed through the flow meter (such as 100 liters)

  • Annubar or Orifice Flowmeter: What Is the Best Application ,

    On page 170, the accuracy of orifice flow meters is stated as 2 percent to 4 percent of full-scale flow, whereas the accuracy of annubars is 075 percent to 20 percent of actual flow Thus at low flows, the accuracy of the annubar is significantly better The stated rangeability is 5:1 for orifices and 10:1 for annubars assuming the maximum ,
