Flow Meters Best for Industrial Use

There are various different kinds of liquid flow meters with unique features that differentiate them according to their accuracy and functionality. In order to know more about the types of flow meters best for industrial use without wastefulness, consider the following options of different volume-based meters.

1. Coriolis Meters

Coriolis meters exist in two plans to provide the true mass flow measurement. One of these designs is a single tube design, whereas the other one consists of two parallel tubes. Coriolis meters are suitable for a broad choice of gas and liquid applications. They are commonly used in industries that include pharmaceutical manufacturing, nuclear facilities, wastewater treatment facilities, custody transfer and natural gas measurement.

2. Differential Pressure Flow Meters

Differential pressure flow meters estimate changes in pressure for the identification of the speed of flow. It has a flow-restrictive orifice that processes the reduction in pressure through the restriction point. The drop in pressure from upstream to downstream are proportional to the flow rate. Sometimes, no moving parts are needed or a rapid response time is required. This is where a differential pressure flow meter is suitable. It is used in industrial applications for the calculation of output of fuels, plain water measurement testing or even chemical manufacturing. They are also used in labs for the control and calculation of the flow of gases while separating or mixing them by the use of chromatography.

3. Positive Displacement Gear Meters:

Positive displacement gear meters have an oval, counter-synchronized gear that is attached to revolve with the liquid flow. The amount of liquid transferred through these gears is well regulated and gives the meters a great accuracy. It is well suited for installation in the toughest situations and even for high viscosity fluids. They are used in hydraulics and they also work great with oil or fuel transfers, in manufacturing and paper and pulp industries. Since stainless steel is used for the, they are the ultimate choices for petrochemical industries or those that involve light or heavy oils.

4. Paddle Wheel Meters

Paddle wheel meters exist in different forms with propellers, oscillating disks and spinning paddle wheels. The spinning parts of a paddle wheel meter deliver a pulse while passing through an optical or magnetic sensor. Such a meter offers brilliant accuracy at low costs. It is usually used in the rural areas for water or wastewater treatment, irrigation, aqua farms, and in plain-water capacity. Because these meter work well with viscous liquids, they are suitable for use in services and the gas and oil industries.

5. Magnetic Flow Meters:

Magnetic meters are of two types: full-bore and insertion. They are high-end liquid flow meters and can be used in chemical manufacturing, petrochemical, mining, paper and pulp manufacturing, industries of foods and beverages and water purification.


According to the above article, it is clear that magnetic flow meters are usually considered as the most suitable flow meters for industrial purposes. They can precisely measure any kind of conductive liquid flow, whether clean or dirty.

Ultrasonic Flow Meters Vs. Magnetic Flow Meters

Choosing the right flow meter technology is quite critical for your system and your ability to trust the meter’s values will depend greatly on the application. All the different kinds of meter technologies have their advantages and disadvantages. However, attention must be given to the nuances of your system and whatever flows through it.

For instance, when it comes to water applications, there are so many different kinds of technologies which could do the job. But the decision isn’t so simple. You must answer many questions regarding the types of flow meters which would be perfect for your system. In case of water applications, the ultrasonic and magnetic flow meters are popular today.

Ultrasonic Flow Meter:

Ultrasonic flow meters can detect and measure the flow rates without the invasion of flow stream or usage of moving parts. For their functioning, ultrasonic flow meters could use various operation principles such as the transit-time ultrasonic flow meter and the Doppler ultrasonic flow meter. Following are the pros and cons of an ultrasonic flow meter:


  • Ultrasonic flow meters are available in much lower costs of installation. There would be no need to shut your system down and even your piping would require no alteration.
  • Lesser moving parts mean lesser maintenance required.
  • They can be used with corrosive solutions as well.
  • These flow meters are rather insensitive to variations in viscosity, temperature, density or pressure.
  • They are available in a diverse range of communication protocols, i.e. Transit Time


  • There could be some errors or shifting of flow signals due to unknown internal piping variables.
  • Problems can arise from the pitting, scaling and fouling which might occur eventually in the older piping systems.
  • There may be some air space in the pipe which could affect the accuracy of ultrasonic flow meters.

Magnetic Flow Meters:

Magnetic flow meters are used to measure the flow rates by using Faraday’s Law of Electromagnetic Induction according to which, a magnetic field is produced by running current through a coil signaling the flow tube. After this, the conductive liquid/media creates a voltage while passing through the magnetic field and the flow tube. The electrodes can detect and measure the voltage that is resulted while the fluid passes through the flow tube. With increasing velocities, the voltage also increases and this signal is eventually changed to volumetric flow. Such flow meters are particularly created for systems which move conductive fluids like acids, water, slurries and caustic liquids.


  • Magnetic flow meters have no flow hindrances or moving parts.
  • They are relevant to all flow profiles and don’t need a straight run.
  • They can respond to rapid changes in flow well.
  • They are applicable to liquids that have heavy particulates.
  • They have a life span of 75 years.


  • The air space in the pipes of magnetic flow meters may affect their accuracy.



Before coming up with just the right flow meter, you must consider both types of flow meters, that is, the ultrasonic and the magnetic flow meters along with their pros and cons.
