A flowmeter is an instrument used to measure linear, nonlinear, mass or volumetric flow rate of a liquid or a gas. Selecting a Flow Meter The basis of good flowmeter selection is a clear understanding of the requirements of the particular application. Therefore, time should be invested in fully evaluating the nature of the process fluid and of the overall installation.


Measuring
the flow of liquids
is a critical need in many industrial plants. In some
operations, the ability to conduct accurate flow measurements is so important
that it can make the difference between making a profit or taking a loss. In
other cases, inaccurate flow measurements or failure to take measurements can
cause serious (or even disastrous) results.


With
most liquid flow measurement instruments, the flow rate is determined
inferentially by measuring the liquid’s velocity or the change in kinetic
energy. Velocity depends on the pressure differential that is forcing the
liquid through a pipe or conduit. Because the pipe’s cross-sectional area is
known and remains constant, the average velocity is an indication of the flow
rate.



 Here are some key questions which need to answered before selecting a flow meter:

  • What is the fluid being measured by the flow meter or flowmeters (air,water,etc…)?
  • Do you require rate measurement and/or totaliser from the flow meter?
  • If the liquid is not water, what viscosity is the liquid?
  • Is the fluid clean?
  • Do you require a local display on the flow meter or do you need an electronic signal output?
  • What is the minimum and maximum flow rate for the flow meter?
  • What is the minimum and maximum process pressure?
  • What is the minimum and maximum process temperature?
  • Is the fluid chemically compatible with the flow meter wetted parts?
  • If this is a process application, what is the size of the pipe?

Type and model Of  Flow Meter

Electromagnetic Flow Meters

The measuring principle of the electromagnetic flowmeter (Magmeter) is based upon the Faraday’s Law of electromagnetic induction; whereby a voltage is induced by an electrical conductor passing through a magnetic field. In electromagnetic flowmeter, the medium acts as the electrical conductor when flowing through the meter tube   read more……
Ultrasonic Flow Meters

Ultrasonic flow meter is a type of flow meter is widely used in industry to measure the flow characteristics of the fluid from the flow velocity, flow capacity, and the total amount of fluid flowing. In addition to measuring the flow properties of the fluid Ultrasonic flow meter can be combined to measure the calories of a fluid by add…. read more
Coriolis Mass Flowmeters

Coriolis mass flow meter remain the most accurate mass flow meter, and they are highly reliable with little need for maintenance. Coriolis meters do not place any obstruction in the flowstream, although bent-tube meters can slow down flow velocity. Straight-tube meters have been developed to address this effect and to suit the needs of sanitary applications, which pose an issue for bent-tube meters. read more…..

Gas Flow Meters

Gas flow meter flow meter is used to measure a fluid that has the characteristics such as gas and not only on a narrow understanding of gases such as natural gas and propane. The discussion here is the gas flow meter is used to measure the flow of a fluid in a form that has a gas, not a liquid and a solid. Therefore, applications for gas flow meter can be used for CNG, LPG​​, Nitrogen, Oxygen, Air, Argon, a mixture of various gases and hot air or steam.        read more….
