Answer / abhishek k sharma

A MASS FLOW METER WORKS ON CORIOLIS FORCE.
THE CORIOLIS FORCE MEANS THE EXTENDED REVERSE FORCES APPLIED
TO THE BODY FOR EXAMPLE
IN MASS FLOW METER THERE IT CONTAINS A "U" SHAPED STEEPED
INSIDE FIXED IN BOTH END AND THE LIQUID WHICH FLOWS WILL
TEND IT TO MAKE FORCE ON STRIP SO THAT IT CHANGES ITS
POSITION .THIS CHANGED WILL BE MEASURED AND THE CHANGE IS
DIRECTLY PROPORTIONAL TO MASS FLOWING RATE

Answer / sandeep patel

mass flow is mass of a sybstance which passes
therough a given point in unit time..

Answer / dinesh sarshiha

Mass flow, also known as mass transfer and bulk flow, is
the movement of material matter. In physics, mass flow
occurs in open systems and is often measured as occurring
when moving across a certain boundary characterized by its
cross-sectional area and a flow rate. In engineering and
biology it may also be a flow of fluids in a tube or vessel
of a certain diameter

Answer / anish kumaran.r

Mass flow is nothing but steam flow. If we need to convert it in to volumetric flow need to divide mass flow by density.

when an eddy current probe is installed inside of a turbine or compressor in case of probe problem same as:crash of head of probe,changing the scale factor because of low measuring gap(physical gap is ok(example=1.14mm)but voltage is reduced(example=-6 volts),is any way to check the probe,when the ohm of probe is ok.thank you,(Karim Tavakoli)

In control valve there are two type of valve seat we can use metal to metal seat & soft seat.On this valve seat i have following doubt. 1)I have never seen practically the internal assembly of valve so my doubt is that basically weather the seat is soft seat or metal its basic MOC is same as valve body(SS or CS) only in soft seat we are using PTFE ring & place on valve seat & in metal this PTFE ring is not threr am i correct??????? 2)what are the common general rule for using metal to metal seat & soft seat,means its depend on process parameter like liquid,gas, steam & on valve leakage class.
