The use of differential pressure as an inferred measurement of a liquid’s rate of flow is well known. Differential pressure flow meters are, by far, the most common units in us… See more

Orifice flow meters are the most popular liquid flow meters in use today. An orifice is simply a flat piece of metal with a specific-sized hole bored in it. Most orifices in use are of the c… See more

Venturi tubes have the advantage of being able to handle large flow volumes at low pressure drops. A venturi tube is essentially a section of pipe with a tapered entrance and a strai… See more

Pitot tubes are generally installed by welding a coupling on a pipe and inserting the probe through the coupling. Use of most pitot tubes is limited to single point measurem… See more
