subject: Flow Meters [print this page] Flow meters are instruments used to measure mass, linear, nonlinear or volumetric flow rate of a gas or a liquid.
To select the right flow meter understand the requirements of its application. Evaluate the nature of the process fluid and the installation procedure.
Some key questions that will help:
oWhat is the fluid the needs to be measured?
oDo you need totalization or rate measurement readings?
oThe viscosity if the liquid is not water
oIs a local display needed or an electronic signal output?
oThe minimum and maximum flow rate, process pressure, process temperature for the flow meter?
oChemical compatibility with the flow meters parts
oSize of the pipe in case of process applications.
Flow measurement devices are rapidly evolving through the development of accurate technologies such as the Pelton wheel flowmeter, which allows for accurate and effective measurement of wide ranging fluid types, including acids, chemicals, hot fats, fuels and water, across low and high flow rates. The technology enables extremely accurate measurements of high-pressure flows and low flow rates, and allows flowmeters to handle a wide range of flow rates and pressures, viscosities, aggressive liquids and environments that may be hazardous.
Flowmeters are available for varied industrial use in the market today, and use technologies that allow for both liquid and gas measurement applications. Some of the popular flowmeter products in the market include
axial flow turbine flow meters
electromagnetic flowmeters
drum type gas meters
vortex flowmeters
ultrasonic flowmeters
rotary piston positive displacement flowmeters
pelton wheel turbine flowmeters
thermal mass gas flowmeters
helical screw positive displacement meters
Leading players in the industry offer solution expertise in the design, manufacture and supply of flow measurement devices. Customers need comprehensive flow meter solutions across all liquid and gas types. Companies that offer these solutions often maintain in-house calibration rigs or access them through partnerships.
Flow meter solutions need to meet quality and precision standards whether in the precise environment of a testing laboratory, or the harsh environment of sub-sea conditions.
