Flow meters are used to measure the flow of air, fluids and gas. Some of the
most popular flow meters are:
peak flow meters,
water flow meters, fuel flow
meters, air flow meters,
ultrasonic flow meters
and flow monitor services. Many flow meters measure the volume of the material
while other flow meters measure the speed, and still other flow meters measure
the mass of the materials. For the most part, flow meters are used to infer mass
flow through calculations that flow meters and flow monitor instruments make
after taking various flow measurements, such as absolute pressure, differential
pressure, viscosity and temperature. Most flow meters are made of three parts:
the primary device, transducer and transmitter. These three flow meters parts
are usually combined so that the flow meter is one complete instrument.
Flow meter distributors offer various instruments for different measurements of
flow. Thermal mass flow meters take measurements with two sensors that work together.
A temperature sensor reference and an active heated sensor take measurements
by calculating how much heat loss occurs in the flowing liquid, and thus these
flow meters can determine the flow rate based on this amount. Another type of
flow meter is the Coriolis mass flow meter, which operates on the basis of the
Coriolis Effect. Basically, an excitation force is applied to the flow meter
tube, causing the fluid or gas to rotate because the acceleration is acting in
opposite directions on both sides of the applied force. A flow meter measurement
can then be taken. Other kinds of flow meters operate using sound: These are
called ultrasonic flow meters, and include several types, like Doppler Effect
flow meters and time-of-flight flow meters.
Flow meter distributors offer products that are useful in a variety of fields.
Medically, flow meters are used to measure a patient’s air intake. These
types of flow meters are called peak
flow meters and are particularly beneficial
for asthma patients. In plumbing, water
flow meters are used to measure the amount
of fluid running through a tube for efficiency purposes. In general, flow meters
are used in many industrial purposes for flow measurements to help companies
determine profit gain or loss. Other industries that benefit from the use of
flow meters, peak flow meters, fuel flow meters, water flow meters and flow
monitor services include automotive, petroleum and gas,
utility services, HVAC, food processing and raw materials.
Each type of flow meter has specific guidelines that must be followed for proper
use. For example, when using gas flow meters, the flow meters must remain full
of gas. Liquid in gas flow meters can affect the flow meter’s accuracy. Similarly,
in order for liquid flow meters to work properly, they must remain full of liquid.
Gas in liquid flow meters can affect the accuracy of flow meters’ readings. Generally,
contaminants of any kind will cause an inaccurate reading of flow meters, so
flow meter distributors advise that flow meters and flow monitor instruments
must be treated with care and cleaned regularly.

Coriolis mass flow meters
are used to measure the force of acceleration resulting from a moving
object towards or away from the center of rotation.
Differential pressure
flow meters are used to measure the flow of fluids and gases
in a pipe by introducing constriction that causes the pressure to drop.
The pipe must be clean to result in accurate measurements.
Insertion flow meters
measure flow at one position in a pipe, and then, based on the measurement,
they estimate the flow rate for the entire pipe.
Magnetic flow meters
measure by creating a magnetic field that is channeled into the liquid
and causes a voltage signal to be sensed that is proportional to the
flow of liquid.
Mass flow meters
are used to measure gas flow and are one of the more popular flow meters.
This meter is relatively unaffected by changes in temperature or pressure
in the tube or pipe.
Open channel flow meters
are used to measure the flow of liquids when they are open to the atmosphere.
Peak flow meters
are used by patients with asthma or other lung disorders to measure
the amount of air patients take into their lungs. These flow meters
allow physicians to determine the severity of the illness.
Positive displacement
flow meters trap liquid to measure its flow by rotating parts
that move between seals and the meter body.
Rotometers have a rotating float that moves vertically through a tapered tube.
Sight flow indicators
allow the operator to view the liquid as it is moving. Some models come
equipped with lights to enhance the visibility of the fluids.
Target flow meters
measure the amount of force that is exerted on a target in a particular
liquid or gas. This should not be used to measure high viscosity liquids
because the target can be damaged.
Thermal flow meters
are meters that use thermal properties of fluids to measure the flow.
The meter is heated and as the liquid flows by, it can tell the flow
rate by the amount of heat lost.
Turbine flow meters
consist of a rotor that measures the fluid when it passes through the
blades. The blade speed is translated into the speed of the fluid
Ultrasonic flow meters
use sound to determine flow rate. Both Doppler Effect meters and time-of-flight
meters are different kinds of this type.
Variable area flow
meters measure by letting the flow stream change the opening
in the meter with a movement of an internal part.
Vortex and fluid flow
meters generate oscillations as a result of the flow that allows
a measurement to be taken.
Water flow meters are flow meters designed for measuring flow rates of water in various channels, tubes, partially filled pipes, streams, and rivers.
