When does the need of measuring the velocity of a liquid arise? Well, there are several such scenarios in which this may be needed. For instance, a big manufacturing industry may need continuous flow of water for cooling purpose. In addition, a chemical manufacturing company will need to measure the flow of a chemical in the liquid form to ensure that just the final product has just the right mix of ingredients. Ultrasonic flow meters happen to be extremely useful in such scenarios. Another industry that needs water flow measurement is the waste water processing industry, where it is necessary to determine the flow of water accurately. Incorrect measurement of the water flow can lead to huge losses that can jeopardize its operating margins. An ultrasonic flow meter is perfect for usage in a wide variety of industries owing to the several benefits that it provides, including absence of moving parts and high accuracy. Measuring the flow of liquids having high turbidity is extremely difficult owing to the fact that the moving parts cannot cut through them. Besides that, chemical compatibility is another important issue to address when measuring the flow of highly reactive liquids such as acids. These liquids can react with the material of the flow meter and eat it up in due course of time. On the other hand, there is absolutely no moving part in ultrasonic flow meters and hence there is no risk of destruction of the flow meter hardware. Way of operation Ultrasonic flow meters have an interesting way of operation. These meters make use of ultrasonic waves that are broadcast towards the moving liquid. When these waves strike anything, these return back. The speed with which these waves return to the transmitter/ receiver happens to indicate the flow of the liquid in question. There are three main types of ultrasonic flow meters available in the market: - Transmission Flow Meters
- Doppler Flow Meters
- Open Channel Flow Meters
Transmission Flow Meters: Transmission flow meters can be further classified as clamp-on (non intrusive) and in-line (intrusive) transmission flow meters. These meters work by measuring the rate at which ultrasonic beam is returned after hitting a particle. Doppler Flow Meters: Doppler Flow Meters make use of Doppler Shift that emanates due to the reflection of an ultrasonic beam when it hits sonically reflective materials. These flow meters are perfect for measuring the flow of slurries, gases that have sound reflecting particles and liquids with bubbles. These meters can also be used for measuring the flow of blood. These meters, however, are not suitable for measuring the flow of clear drinking water. Given the several advantages of these meters and the fact that there are no components that can get corroded after long time usage, these meters are perfect for usage in a variety of industries. These meters have an exceptionally long life and hence help in significant cost savings as well. If you are looking forward to installation of splendid quality meters for measuring flow of any liquid, consider the ultrasonic flow meters!
