Mechanical Flow Meters: Types And Advantages

mechanical flow meters

The use of flow measuring tools in various industries is proving beneficial. These devices are capable of computing the number of liquids such as water with accuracy. However, the modern age of measuring tools is electronic. But still, there are many that use mechanical flow meters. In some situations, the use of electronic meters is not possible. So, mechanical meters with moving parts like rotors and turbines are used for measurements. They are also useful in measuring the flow rate of liquids and gases.

There are many types of mechanical flow rate measuring devices, so let’s take a look at them.

Piston meter

It is the mechanical flow meter that is used to measure the definite volume of water. It is combined with a piston in the chamber that works to measure the volume of liquid. The piston will rotate when the chamber fills up with the water and make it empty. The measurement of total volume can be done by counting the rotation cycles. These are the precision meters that are apt for measuring the flow of low-velocity liquids. The high accuracy of these meters works to measure the lowest flow rates of water.

Paddlewheel meter

As the name suggests, this meter comes with a paddle that rotates when the water flows through the pipelines. The paddlewheel works vertically to the flow way of water along with the rotor axis. The rotor axis reduces the contact between paddles and the flowing water. Thus the paddle rotates at the speed relative to the flow of liquid in the pipe. A sensor, paddlewheel, display controller, and pipe fitting are the main parts of this flow meter. The paddle wheel would rotate, which induces a voltage pulse. The electronic unit will convert the pulses in the flow-based units to deliver the flow rate result.

Woltmann meters

These mechanical meters are used in industrial applications where reliability and accuracy are crucial. These are reliable flow meters that are accessible to use in various connections and lengths. The best feature of these meters is that they can be used in every work environment. These devices come with a propeller that rotates with the flow. The inlet and outlet of this device are designed to prevent hydraulic thrust. They are versatile flow rate measuring tools that can easily give accurate results even with high and low water pressure. In order to calculate the flow, the rotation of the propeller is used.

Venturi meter

This type of meter is used to measure the flow rate of water by narrowing the flow. It mainly works to measure the high pressure of the flow and have a low-pressure drop. It has mainly three components that work for accurate measuring. The first part has a converging cone, the middle part has a cylindrical cone, and the last is a separating cone. It is placed in the pipeline to measure the flow. When the flow enters the meter, the pressure will drop. When it reaches the throat, the speed of flow will improve. So, the difference between the inlet and throat section flow would be the measurement.

Advantages of mechanical Flow Meters

High accuracy and repeatability

Mechanical flow meters are accurate when it comes to measuring 100 percent correct flow rates. They are equipped with high-performing components that fetch accurate results by reading the flow of liquids. Moreover, these are the sturdy measuring gears that are used in industries to compute the rate repeatedly. They can also handle the high pressure of water flow and measure the flow rate precisely.

Longer span

In an industrial environment, the use of measuring devices is required for the extended runs. However, the flow rate measuring is essential to control the quality during the manufacturing process. So, the tools that have a longer span are ideal to use. A mechanical flow meter has the feature to work for a longer duration. They are also comparatively inexpensive during initial installation and require low maintenance. So, if you have a low budget, then using these meters is a great deal.

No external supply is needed.

These meters do not require an external power supply. They completely work by with the internal components to measure the flow rate. So, in order to control the cost of using flow rate sensors, they are the best option.

Designed for easy installation

These meters are really easy to install. They do not require any technical expertise for installation as you can easily place them between the pipelines. However, in order to check the correct flow rate, one must have the knowledge to attain correct measurements. But, they are quite easy and convenient to use in various industries.

Forward and reverse flow measuring

They are suitable for measuring flow rate in forward and reverse flow conditions. The accuracy will remain precise, and it also does not affect the working of the device.

Conclusion

To conclude, using a mechanical flow meter is always a great solution for industries. It is an easy flow rate device that is available in the market to purchase from professional manufacturers. The flow rate sensors with mechanical functions are precise and convenient.
