voolumõõdik

Voolumõõdik, also known as a flow meter or flowmeter, is a device used to measure the rate at which a fluid, such as a liquid or gas, flows through a pipe or channel. These measurements are crucial in a wide variety of industrial, commercial, and scientific applications.

Different types of voolumõõdik exist, each employing distinct principles to determine flow rate. Common types include differential pressure flow meters, which measure the pressure drop across a restriction in the flow path; velocity flow meters, such as turbine or ultrasonic meters, which measure the speed of the fluid; and positive displacement flow meters, which trap and count a fixed volume of fluid with each rotation or cycle. Other technologies include vortex, electromagnetic, and Coriolis flow meters, each suited for specific fluid types and operating conditions.

The selection of a voolumõõdik depends on factors such as the fluid's properties (viscosity, density, corrosiveness), the required accuracy, the flow rate range, operating pressure and temperature, and cost considerations. Voolumõõdik are essential for process control, monitoring, billing, and safety in industries like oil and gas, water treatment, chemical manufacturing, and food and beverage production. Their accurate measurement helps optimize processes, prevent waste, and ensure product quality.
