A Venturi meter is a primary flow measurement device that uses the principle of conservation of energy to measure the flow rate of a fluid.

A flow straightener is used to eliminate swirl in the flow, which can cause inaccurate flow measurements.

Ultrasonic flow meters are non-intrusive flow measurement devices that use ultrasonic waves to measure the flow rate of a fluid.

Magnetic flow meters operate on the principle of Faraday's law of induction, which states that a voltage is induced in a conductor when it moves through a magnetic field.

Gear flow meters are positive displacement flow meters that use a pair of gears to measure the flow rate of a fluid.

Mass flow meters measure the mass of the fluid, while volumetric flow meters measure the volume of the fluid.

Vortex shedding flow meters are inferential flow meters that use the principle of vortex shedding to measure the flow rate of a fluid.

Coriolis flow meters offer high accuracy, a wide flow range, and low pressure drop.

Pitot tubes are velocity flow meters that use the principle of Bernoulli's equation to measure the flow rate of a fluid.

Turbine flow meters operate on the principle of Bernoulli's equation, which states that the pressure of a fluid decreases as its velocity increases.

Venturi meters are area flow meters that use the principle of conservation of energy to measure the flow rate of a fluid.

Thermal flow meters offer low pressure drop, making them suitable for applications where pressure drop is a concern.

Coriolis flow meters are mass flow meters that use the principle of Coriolis force to measure the flow rate of a fluid.

Vortex shedding flow meters operate on the principle of Bernoulli's equation, which states that the pressure of a fluid decreases as its velocity increases.

Magnetic flow meters are electromagnetic flow meters that use the principle of Faraday's law of induction to measure the flow rate of a fluid.
