Flow Measurement
Types of Vortex Flow Meter Sensors
Vortex flow meter operates on the physical principle of the Karman vortex street. When a fluid flows pass a bluff body, vortices are alternately forced on the side of that
What is Segmental Wedge Flow Meter ?
The segmental wedge flow meter element has a V-shaped restriction cast or welded into a flanged meter body that creates a differential pressure. The functional principle of this measuring instrument
Ultrasonic Doppler Flow Meter Advantages and Disadvantages
A Ultrasonic Doppler flow meter transmits an acoustic signal into the flow stream at a specific frequency. This signal reflects off particulate, either solids or gas bubbles. Ultrasonic Doppler Flow
Transit Time Flow Meter Advantages and Disadvantages
Transmit time flow meter sends and receives the ultrasonic waves between transducers in both the upstream and downstream directions in the pipe. At no flow conditions, It takes the same time
How to Read Circular Chart Recorder for Flow Measurement
Flow Transmitter output in square-root value and chart recorder prints flow value in range 0 to 100%. How to read circular chart recorder ? The simplified formula for the gas flow,
Flow Switch : What is it ?
Flow Switch is a mechanical switch that is switched on or off in response to the flow or non-flow of a fluid such as air or water. The switch typically operates
Turbine Flow Meter Verification
Question : ” We have a turbine flow meter, gas chromotograph & flow computer installed at our site, similar units installed at GAIL terminal also. How metering can be done
Types of Variable Area Flow Meters
In this type of orifice meter, there is a fixed aperture and flow is indicated by a drop in differential pressure. In area meter, there is a variable orifice and
Flow Transmitters Questions and Answers
