Tips for Buying High Quality Flow Meter Switches
Flow meter is an instrument that is used to gauge
the flow of gases or fluid through a pipe. Flow
measurement applications differ extensively with
respect to the conditional benchmarks,
situational limitations, and engineering
requirements. Flow meter has other names such
as fluid meter, fluid sensor, flow sensor and
flow gauge. They have a wide range of
applications across different industries based on
its basic function, which is to offer precise
monitoring and measurement for flow of fluids or
gases.

A few examples of flow meter applications are
semi-conductor equipment cooling, thermal
control, industrial laser coolant systems, fire
sprinkler systems, air-conditioning systems, and
batch processing. It is very important that you
choose the right flow meter or a flow switch.
Every application needs a different combination
of flow meter and switch depending on various
factors listed below.

Various Factors Of Flow Meter Switches

• The type of fluid or gas to be measured.
• Inertness between the flow meter material and
  the fluid or gas passing through it.
• The nature of the process whether
  intermittent or perpetual.
• Circumstances of the surroundings whether
  working in hazardous situation.
• Extent of precision required.
• Maximum and minimum flow rates.
• Viscosity of the fluid or gas.
• Temperature of the fluid or gas.
• Type of readings required.

Do You Need a Flow Meter?
In most systems of simpler nature, flow meters
are used to measure the rate of flow of a fluid
or gas through a pipe. For such applications, you
need the most basic flow meter that you can
easily procured from your vendor at a very
affordable price. These flow meters produce
results that are fairly accurate, give or take
5. However, if you are working on a very
sensitive system that calls for more precision,
the sophisticated versions of flow meters are
your best bet. Of course, they are somewhat
complex in nature, but the results are thorough
and more accurate.
6
Pressure vs. Resistance
Before you rush to buy a flow meter, it is very
important that you first study the fundamentals
of the fluid or gas that flows through the
system. The properties of fluid or gas would
determine the kind of flow meter that should be
installed. The equation between pressure and
resistance is closely related to the viscosity
and rate of flow of the fluid or gas. There are
two kinds of fluids Newtonian Non - Newtonian.
The Newtonian fluids are straightforward.
7
There is a positive correlation between the
pressure applied to these fluids and the
resistance against the side of the pipes. They
flow slower on the side but faster in the center
of the pipe. Mineral oil, water, and milk are
some examples of Newtonian fluids. On the
other hand, the Non-Newtonian fluids exhibit an
indecisive behaviour since there is no relation
between the pressure applied and the resistance
against the walls of the pipe. So, it is
difficult to predict their viscosity and change
in the rate of flow of such fluids at a given
time. Curd, shampoo, paints, etc. are
non-Newtonian fluids.
8
Go for a Broader Turndown
Turndown indicates the ratio of maximum flow rate
and minimum flow rate for a fluid. The flow meter
with a broader turndown is particularly
beneficial when you cannot predict the extent to
which the flow rate of the fluid can rise or
drop. A flow meter having a comprehensive
turndown would accommodate the unforeseen
variations in the flow rate.
9
Selecting Flow Switches
When it comes to selecting a flow switch, you
need a flow switch that is attuned to the
conditions under which it would be employed. The
manufacturers of flow switches design variants
that are meant to be used for specific industrial
applications. The systems that involve fluids and
gases flowing through them at high temperatures
call for robust flow switches that can withstand
extreme temperatures, ranging between -50 to 220
degrees Celsius. Similarly, you can find flow
switches that are especially meant to be used in
systems commissioning high-pressure fluids and
gases for example, up to 40 bar system pressure.
10
Hazardous fluids like oils can cause severe
damage to the environment and system
interruption. Having a reliable, leak-proof,
dirt-resistant flow switch decreases the odds of
the system breaking down. Flow switches are
usually made from stainless steel and brass. The
fluid or gas should not react with the materials
from which the flow switches are crafted
otherwise, the fluid or gas would run the risk of
contamination simultaneously putting the physical
integrity of the flow switches at stake.
11
Lastly, you should consider the cost factor. Flow
meters and flow switches are critical components
of an industrial application. Cheap flow meters
and switches would not necessarily be high
quality. They often cause issues such as leakage,
corrosion, or functional breakdown. It would be
wise of you to spend on heavy-duty flow meters
and flow switches. They will cost a bit more but
will save you a lot of money over a long term.
