A differential pressure flowmeter is a flowmeter that measures fluid flow rate by detecting the pressure difference created as the fluid passes through a conduit. This pressure difference, typically generated across a constraining structure like an orifice plate, is used to calculate the flow rate. Differential pressure flowmeters offer a cost-effective solution compared to other flowmeter types and are suitable for high-temperature and high-pressure environments. However, they can have a limited measuring range and may incur high-pressure loss.
Differential pressure flowmeters are versatile tools employed in various fields:
The operational principle is based on Bernoulli's theorem. A constraining structure, like an orifice, is installed in the pipeline, causing a velocity increase and pressure decrease in the fluid. Pressure sensors measure the differential pressure upstream and downstream of the structure. This differential pressure, proportional to the square root of the flow rate, allows for flow rate estimation.
Stable flow before the orifice is essential for accurate measurement, requiring a straight pipe length of 5 to 10 times the pipe diameter before the orifice.
Differential pressure flowmeters come in various forms:
