This allows it to accurately measure flows even if there are bends or other obstacles along its path. It measures changes in pressure across two points on opposite sides of a pipe with no obstructions between them. Another common type is called differential pressure. This information can then be used to calculate volumetric flow rates in units like gallons per minute (GPM). These vortices can then be measured using ultrasonic sensors to determine how fast they move past one another. Vortex shedding which measures how fast vortices form downstream from an object moving through a liquid medium such as air or water. Turbine flow meter uses rotors to determine how much fluid has passed by measuring the rotation speed of these rotors as they pass through the fluid stream. Some common examples include Coriolis Mass and Ultrasonic Liquid type Meters. This makes them ideal for high-pressure/high-temperature applications where fluids may erode metal components over time. Whereas UTs have no moving parts so there is less chance of failure compared to MTs which use turbines inside a tube filled with fluid. Including combustible gases or chemicals that could explode if exposed to excessive heat or pressure changes due to incorrect measurements being taken. Like acid or alkaline solutions as well as hazardous materials. Which makes them ideal for use with corrosive fluids. This means they can provide accurate readings even if there is some turbulence in the line. Like Bernoulli’s equation or conservation of mass in order to accurately calculate how much fluid has passed through them at any given time. Both work by taking advantage of fluid dynamics principles. Turbines are best suited for smaller diameter lines. PD is typically used for large-diameter pipes. Including positive displacement (PD), turbine (PT), magnetic (MT) and ultrasonic (UT).

It comes in many types depending on the application requirements.
