Types of Flow Meters

Flow meters are instruments that are utilized to quantify the particular flow rates of liquids as well as gases. Measurement can come in terms of volumetric or mass flow rate. Volumetric flow rates are generally given in cubic metres per second. Mass flow rates are given in kgs per second.

Flow meters are employed in various scenarios. It's possible you could have used a flow meter in your healthcare provider's office to assess your current lung capacity. That is not really what this information is about. We are taking a look at flow meters that have commercial applications.

There are various methods associated with acquiring flow measurements. Ultrasound as well as Doppler shift flow meters make use of the alterations generated in sound waves to correlate a specific rate of movement for the particular material passing through the gauge.

how do flowmeters work?

When it comes to the ultrasonic flow meter, two transmitters of ultrasound sound waves are generally located on the ends of the pipe wherein the measurement will occur. Every transmitter transmits a blip of sound. Each transmitter acts as a recipient of the sound wave transmitted by the alternate transmitter. A single burst of sound is transmitted towards the movement of the fluid and the second is sent against the flow. Depending on that which is understood about the material of the pipe and the liquid or gas moving in it, the rate of flow can be established. This is just a computation depending on the passed time that it takes for the sound waves to reach the opposite receiver.

Flow Meters of the Doppler shift variety employ modifications to amplitude and frequency of a sound wave as it bounces away from particles and bubbles in the flowing liquid. These differences can be assessed to find the flow rate. The returned echo is directly related to the flow rate of the substance when it moves through the pipe. (Be aware that doppler varieties are not perfect for piping transporting drinking water or any other clear liquids. Particles and/or air diffussion is critical for proper operation.)

A different sort of flow meter is that of the Coriolis flow meter. This kind of device works by using the Coriolis effect to figure out the mass of a substance passing within two vibrating pipes or tubes. The concept guiding this is that by knowing the difference in the properties of the particular wave patterns inside the vibrating pipes, you'll be able to correlate the actual flow rate of the material going within.

Despite the fact that you can find several types of non-intrusive flow meters, your decision will depend on the particular application. Will you require a lasting device for constant process monitoring? Or will a portable, hand-held model fit your needs?

Check out the Micronics options. These include permanent flowmeters available from Control Plus. You end up getting easy, accurate flow measurement from outside the pipe within a few minutes of opening the case.
