Flow Meter Filling Machines
Flow meters are used for measuring the flow rate or quantity of a moving
fluid or gas generally used in the filling machinery. Most of the flow
meters are based on the velocity of the fluid flow through a cross section
of pipe or change in Kinetic energy with temperature or any such stimulant.
Types
There are basically three types of flow meter:
- Volumetric meters
Volumetric meters are generally used for liquids without particles.
They are further of two types namely timed flow meters and piston
rotary fillers. The timed flow volumetric fillers can be used to
fill products from water to oils and creams. It is a highly accurate
system. It is installed with flow control adjusters. It has a pump
and no drip fill heads. The body is generally of heavy-duty
stainless steel. The rotary piston fillers are more suitable for
creams gels and pastes. This is more suitable for food,
pharmaceutical and cosmetic industry.

- Electromagnetic magnetic flow meter
In the Electromagnetic magnetic flow meter filling process the
fluid is passed through a magnetic field. The magnetic fields
interaction with the fluid creates an electric charge, which is used
to measure the speed of the flow. The system is based on the
physical characteristics of the liquids and is a foolproof method
for all conductive fluids.
- Mass flow meters
In Mass flow meters the liquid flow is measured in terms of mass
flow. These are generally based on thermal meters that sense the
heated element from the liquid flow path. It is a state of the art
static system for all liquids and is the most accurate. In a
Coriolis mass flow meter fluid is passed through the vibrating flow
pipe causing a deflection of the flow tube proportional to the mall
flow rate of the liquid.
