Flowmeter - Information required to size a flowmeter


Application _________________________________________________________________________


There are many types to consider; turbine, vane, positive displacement, magmeter, Coriolis

mass flow, thermal dispersion, vortex, rotameter, differential

pressure, non-invasive, others.

Most often, the conditions given below dictate what style is to be used.

Meter: Insertion style or inline



Body material


Connection (NPT, ANSI, Tri-Clamp, etc.) _______________________________
Media: ____________________ temperature ______________________________


particulate/size ______________________________

Viscosity or specific gravity ____________________

Flow rate: min/max: ____________________ normal: _________ pulsating? _________
Acceptable pressure drop ____________________

Accuracy _______________________________

Output:Switches? _________ Set point _________ On increasing or decreasing _________

Analog signal? _________

Direct or remote mount meter ___________ display? _________ Voltage _________
NEMA rating ______________

Other information regarding the application that may be important. _______________________________

The above will help determine possible types of meters to use, but additional information will

probably be needed depending on the style of meter chosen.
