Flow Meters: Types, Cost, Advantages, and Applications

A flow meter is a device that determines the volume or mass of a gas or liquid.
Flow meters can be used to measure open channels such as rivers or streams. You use to get all here.
Alternatively, the most utility from a flow meter and the widest range of flow meters are focused on measuring gases and liquids in a pipe.
The most significant advantages of the best flow meters improve precision, accuracy, and resolution of the fluid measurement.

Mass Flow Meters of Various Types

I have tried to explain to you some of the types, costs, and advantages of the flow meter. Read below for more details/

Flowmeter with Coriolis

A Coriolis mass flow meter calculates mass based on inertia.

A small actuator within the meter vibrates the tube as a dense gas or liquid passes through it.
The acceleration produces a measurable twisting force on the tube that is proportional to mass.
Coriolis with dual curved tubes are more sensitive and have a lower pressure drop.
The most reliable type of mass flow meter is the Coriolis meter.

Coriolis flowmeters are used in various critical, demanding applications, including oil and gas, water, power, chemical, food and beverage, and life sciences.
True mass flow measurement is one of the benefits of Coriolis mass flow meters.

Temperature and density measurements.
Mass flow measurements have a high degree of precision.
Density measurement that is extremely precise.
Pressure, temperature, and viscosity have no effect.
No requirement for inlet and outlet regions.

Thermoelectric Mass Flow Meter

The convective heat transfer of a burned surface to the flowing gas or liquid is used to calculate the flow rate of a thermal mass flow meter.
Volumetric measurements influence by process and environmental conditions, which can change the unit volume.

Changes in viscosity, temperature, pressure or density do not affect mass flow measurement.
The flow meter used here is perfect for helping you get flow.

They use to monitor or control mass-related processes such as chemical reactions, which rely on the relative masses of unreacted substances.

Thermal mass flow meters have the following advantages:

There is no need for temperature or pressure compensation with a true mass flow meter.
It has a wide range ratio, up to 1:200, and can measure gas velocity from 100Nm/s to 0.5Nm/s.

Disadvantages Thermal mass flow meters (TMFs):

Anti-vibration performance is second to none.
Installation and upkeep are simple.

Mass Flow Meter for Impeller Turbines

An impeller turbine mass flow meter uses two rotating elements in the fluid stream, namely a turbine and an impeller.
Both have channels or pathways through which the fluid can flow. The impeller rotates at a constant speed and is starts by a synchronous motor.

The motor moves the impeller through a magnetic coupling, imparting an angular velocity on the fluid as it flows through the meter.
The downstream turbine removes all of the fluid’s angular momentum and receives torque proportional to the angular momentum.
The turbine is held in place by a spring that deflects through an angle proportional to the torques exerted by the fluid, yielding a mass flow measurement.

Mass flow meter for impeller turbines advantages includes:
Excellent measuring precision when it comes to gas measurements.
There is no need for inlet and outlet sections.
There is no external power supply.

Mass Flow Meter for Twin Turbines

The principle of fluid inertia governs the operation of twin turbine mass flow meters.
Within the tube, they join by a flexible coupling. As each turbine wheel attempts to spin at its speed, the fluid’s inertia creates a differential torque between them.

The greater the angular displacement between the two wheels, the greater the mass flow rate.
A volume sensing device is a turbine flow meter.
The freely suspended turbine blades rotate as liquid or gas passes through the turbine housing.
The turbine rotor’s velocity is proportional to the velocity of the fluid passing through the flow meter.

Its advantages include:

(1) High accuracy is one of the benefits of a turbine flowmeter.

It is generally 0.25 percent, 0.5 percent for liquids, 1.5 percent for gas turbine flow meters, and 0.5 percent 1 percent for special types. Turbine flowmeters are the most accurate flowmeters when compared to other types of flow meters.

(2) Reproducibility

Short-term repeatability ranges from 0.05 to 0.2 percent. It can uses for custody transfer if the flow meters are measure accurately.

(3) A wide measuring range is one of the benefits of a turbine flow meter.

The turn-down ratio for a large-sized turbine sensor can be 40:110:1, while for a small sensor tube, it can be 6:1 or 5:1.

(4) Signal of pulse frequency output

Suitable for comprehensive metering and computer connection, with no zero drift and a high anti-interference capability. The turbine sensor generates a very high-frequency signal (34Hz) with a high signal resolution.

(5) Capable of measuring high pressures

A high-pressure type meter’s body is simple to construct.

(6) Many different types of structures can be made to fit the needs of various measurement purposes, such as thread or flange type, or even tri-clamp type for hygienic purposes.

Summary 

In this article, we have explained to you some of the flow meters types. You have seen some of the type flow. When you want to get cost, then read this article because we explain all things here. You need to check those flow meters to help you with various things.
