Questions & Answers
Questions and answers about flow measurement
11,750 m3/h to CFM and 550 mbar to inches of water conversion
I am looking to convert 11,750 m3/h at 550 mbar 355KW to CFM and Static Pressure into inches of water?
11,750 m3/h to CFM = 6915.7889, using this volume flow rate converter.
550 mbar to inches of water = 220.804692, using this pressure converter.
Utility & process streams
What’s the basic difference between process streams & utility streams, supposing a statement: “Pitot tubes are rarely used for process streams but are occasionally used with utility streams where high accuracy is not required”?
“Utility” means applications like heating & ventilation system in a building, and “Process” would be where product is being transported such as a gas pipeline, or adding ingredients in food processing where the measurement has to be more much more precise.
Petrol pump flow measurement
Which flow measurement device is used in petrol pumps, Is it Venturimeter, since it provides the maximum amount of accuracy in the head type category?
Typically a metering pump is used to measure and transfer fuel in a petrol station fuel dispenser.
Coriolis Mass Flow Meter
How a coriolis mass flow meter work?
There are two types of coriolis flow meter, a straight tube and a curved tube design.
This video explains visually using computer animation how a straight tube coriolis mass flowmeter works and is used to measure the flow velocity and density of different types of fluids.
This page explains the operating principle of a curved tube coriolis flow meter and includes animated graphics to illustrate the flow meter in operation.
For more info on flow meters in general this guide to the types of fluid flow meters provides an introduction to the various ways of measuring the flow of liquids.
Vortex flow-meter output
Does a vortex flow meter have a linear or square root output?
The output from a vortex flow-meter is linear.
