Water flow measurement is conducted using countless methods around the world. Municipal water supplies. Waste management facilities. Industrial cooling systems. There is an extensive range of challenging application areas where water flow measurement must be conducted accurately and repeatedly.

SHELOK Coriolis Flow Meter

Numerous device types are suitable for water flow measurement, including basic variable area, turbine, paddle wheel, and flanged flow meters. Among the most universal water flow measurement tools worldwide, however, are Coriolis mass flow meters. In this blog post, SHELOK highlights our innovative range of Coriolis mass flow meters for water flow measurement in more detail.

What are Coriolis Mass Flow Meters?

Water flow measurement is commonly conducted according to the Coriolis mass flow principle. This calculates the linear mass flow of water as a function of the twisting forces generated as it flows through an oscillating tube.

To exploit this principle, Coriolis mass flow meters?utilize a D- or U-shaped tube that is energized by constant vibration. As the water flows through this section, high velocities are induced which alter the frequency vibration. This causes the tube to twist. Integrated sensors measure the phase shifting of the pipe as a linear output that is proportional to mass flow. Head-mount indicators display the water flow measurement in real-time, enabling tight control of processing parameters for industrial coolant systems.

Coriolis Mass Flow Meters applications:

Coriolis flow meter principle of operation allows working with a wide variety of mediums. The devices can work with contaminated media because the sensors are not in contact with the flow. Coriolis flow meter is commonly used to work with the following substances:

• Gases
• Water
• Air
• Fuel
• Viscous materials

Such mass flow?meter is even capable to measure slurry materials.

Coriolis flow meter advantages and disadvantages

After considering the flow sensor design and its principle of work, let’s look at main advantages and disadvantages of such device.

Advantages of a Coriolis flow meter:

• Accuracy of measurements
• High repeatability
• No dependence on flow direction
• Lack of moving parts
• The minimum required tech. service
• Ability to work with very viscous substances

Disadvantages of Coriolis flow meter:

• A small range of dynamics
• Large dimensions
• External vibration can affect the result
• Sensitivity to temperature changes

Some of such issues can be corrected by improving the design of the device. For example, the user can minimize vibration affecting on the device by installing the equipment on rubber sealing, etc.

In general, these types of transducers represent a simple and effective way to measure flow parameters in pipelines. However, they need stable physical conditions for operation.
