Ultrasonic Flow Meter

As you may know, flowmeters are commonly separated into two different categories, one for flow meters which measure the rate of flow by volume and the other which measures the rate of flow by the mass of the fluid.

Doppler flow meters, or ultrasonic flow meters, differ from the norm as they utilize sound to determine the rate of flow within a system. These flow meters are a great fit for applications in the wastewater industry or similar applications that have dirty liquids that are water based or conductive. Read More…Request for Quote

Ultrasonic flow meters rely on the Doppler effect, which is a term that represents the shift in frequencies that happens when the ultrasonic signal is reflected in the form of bubbles in motion or suspended particles. The transducer in the flow meter transmits ultrasonic sound through the pipe that contains the flowing fluid, the bubbles or particles will reflect these sound waves with different frequencies depending on the rate of flow of the fluid.

This data is picked up by a second transducer which will report the difference, this system allows for accurate measurements of the flow rate. These flow meters are ideal for applications where low maintenance, chemical compatibility and low pressure drop are necessary. It is important to note that ultrasonic flow meters will not work with drinkable or distilled water as the liquid is too clean to measure the change in frequencies.

Ultrasonic flow meters are commonly made from steel or similar metals as they withstand the corrosive environments that ultrasonic flow meters are often placed in. Before purchasing an ultrasonic flow meter it is important to consider the size of the pipe, minimum and maximum rate of flow and the minimum/maximum of both the temperature and pressure needed.

As with all things in the manufacturing world it is essential to consult an expert in the field before making a large purchase. We suggest contacting trusted flow meter manufactures to see if they can provide a high quality solution based on your unique specifications and requirements.
