A Guide to Ultrasonic Flow Meters

When selecting an ultrasonic flow meter you need to keep a couple things in mind. This article is going to take a look at some features that you need to have on your ultrasonic flow meter so that you can be sure you have what you need.

Important Ultrasonic Flow Meters

The first is that it is easily installed and can be clamped onto the outside of the pipe so and will not interrupt the flow inside the pipe. This helps to get the most accurate measurement and assure that the meter is not affecting the flow. The installation should be minimally intrusive without a high overhead. The ultrasonic flow meter flow meter should be able to measure the flow of almost any liquid including de-mineralized water.

The flow meter should be able to measure pipe sizes from ten to seven thousand millimeters in diameter. It is also important to make sure that the flow meter can measure hazardous materials. In addition you want to make sure that you get one that is capable of being an ultrasonic gas flow meter as well as measuring liquid.

One of the most important parts of an ultrasonic flow meter is the inputs. You need to have both analogue and digital inputs that are capable of multiple processes for measuring temperature, relays and pressure. In addition these models should be able to log the data without any external help.

A portable non contact ultrasonic flow meter featuring a clamp on design will be able to measure the flow of material through clamp on transducers that attach to the outside of the pipe work. Something to be aware of is the fact that transit time flow meters, also known as "time of flight" meters are mainly used for measurement of clean liquids, although most should be able to tolerate less than five percent solids.

The principle behind the flow meter is acoustic waves with a frequency of 20 kilohertz emitted from one transducer to the other side of the pipe back to the opposite transducer require less time when traveling in the opposite direction. The differential transit time of the signals is proportional to the flow rate of the fluid.

As you can see there are many high level concepts for ultrasonic flow meters, but understanding the basics of how they function can help you to choose the right one. Hopefully now you understand the basic concepts and are able to make the choice on your own.
