Magnetic Flow / Magflow Meters
Since their introduction in the 1950s, Magflow electromagnetic flow meters have become one of the most widely used flowmeter types for measuring water and other liquids. Also known as Magmeters, magnetic flow meters or…
Paddle Wheel
Principles of Operation Paddle wheel flow meters consist of three primary components: the paddle wheel sensor, the pipe fitting and the display/controller. The paddle wheel sensor consists of a freely rotating wheel | impeller…
Turbine
Principles of Operation The basic construction of turbine flow meters includes a bladed turbine rotor which is axially suspended in the pipe. As the fluid flows through the pipe, it causes the rotor to spin on its axis…
Vortex
Selecting Vortex Flow Meters Vortex Flow Meter Principle of Operation Under certain conditions vortices regularly form downstream of an object (bluff body) placed in a flowing fluid and shed on alternating sides of the stream.
Thermal Mass
Principles of Operation Thermal mass flow meters employ the thermal dispersion principle whereby the rate of heat absorbed by a fluid flowing in a pipe or duct is directly proportional to its mass flow.
Ultrasonic Flow Meters
The ultrasonic flow meter | sensor is a non-invasive volume flow measurement tool, which employs one of two basic principles of operation, namely transit-time and Doppler Effect technologies…
Oval Gear Flow Meters
Oval gear flow meters are traditional, mechanical, positive displacement (PD) flow meters, first invented more than 50 years ago by OVAL Corporation of Japan and now widely used for flow metering applications.
