Orifice Flowmeter Rangeability
The orifice flow meter only allows 3:1 rangeability to maintain accuracy. It is the most used flow measurement device in oil & gas plants.
Flow Measurement: Learn about Flow Sensors like Orifice, Venturi, Annubar, Pitot, Magnetic, Turbine, Ultrasonic, Coriolis flow meters, etc.

Configure the instruments in flow control loop to sense and display process variable with the loop controller actuating two split-ranged control valves.
The main use of a condensate pot is for maximizing the accuracy of differential pressure flow measurement on steam (or vapor) applications.
In this post, you can read the basic flow measurement questions and answers on flow meters which are useful for the viva, tests, interviews.
Has this question troubled you that viscosity is not included in the Orifice equation? This article explains importance of Reynolds number.
A water cut meter measures the water content (cut) of crude oil and hydrocarbons as they flow through a pipeline.
In the olden days of DP Flow Measurement, the square-root function was performed in a separate device called a square root extractor.
When a flow element is inserted in a closed passage of fluid in piping, a differential pressure is produced between the upstream and downstream.
A square root Function is required for Orifice Flow Transmitter as relationship of flow versus pressure is not linear but has a square-root relationship.
Orifice Plate Flow Requirements are to use straight run pipe length or a flow conditioner to reduce the straight run requirement.
