Answer / yogesh pai

Volumetric flow meter gives flow rate in terms of volume
viz liters/hr,gallon, m3/hr etc whereas mass flow meter
(coriolis) gives direct mass flwo rate viz kg/hr/tons/hr etc
Usually mass is derived by multiplying volume with product
density.
Volumetric flowmetering is affected by changes in the
temperature, pressure, density, viscosity, and flow profile
of the process fluid.
Coriolis flowmetering provides direct mass measurement that
is unaffected by changing fluid characteristics.

Answer / giridharan

mass flowmeter
density= mass/volume

mass = density* volume

so it can be expressed as measurement of fluid volume and
density

the example are coroilis ,thermal flowmeter

the volumetric flow is area*velocity
so it has the various type
magnetic,vortex,turbine,ultrasonic....and positive
displacement ...

Usually mass is derived by multiplying volume with product

volumetric flow gives how much volume is passing through a
given point,it does not give the real mass of fluid is
passing.Mass flow is highly depends on the density as well
as on temperature,change in these changes the mass flow.

Answer / sk.raffique

Volumetric flom means its respective to the ratio for
example AC drive 0-50 hz = 0-100 ton/hr then if we select
volumetric mode if set point is 60 t/h it will rotate for
30 hz of speed irrespective of feedback what u get thats
the work proportional to set point. whereas in mass flow or
gravimetric mode it should reach the set point what u gave
irrespective of frequency it varies in between 0-50.
but in volumetric the speed is constant w.r.t to SP

if we open the inlet of an air regulator ,how it will affect the out put of regulator? (out put of regulator is using to operate an on-off valve.it is an air to open valve,and valve is in open position.my doubt is air regulator will hold the valve in open or not,if there is no consumption or leak in regulator out put side ,we only loose the input pressure.)
