There are various ultrasonic flow meter brands available at Cannon Water Technology. We provide a number of components and tools; however, we are well-known suppliers of good-quality ultrasonic flow meter brands such as Blue-White, Seametrics, Stenner, and so on.
Ultrasonic Flow Transmitter Working Principle
The working of handheld ultrasonic flow meter is simple and non-invasive, meaning the meter does not come into direct contact with the fluid. It emits high-frequency sound waves into the fluid being measured and this sound waves travel through the fluid and bounce off the particles/bubbles present in the flow. The meter's transducers detect the reflected sound waves and measure the time it takes for them to return to the transducers. The ultrasonic water flow meter calculates the velocity of the fluid and converts it into flow rate and volume measurements based on the time it takes for the sound waves to travel and return.
Types of Ultrasonic Flow Meters Available at Cannon Water Technology
There are mainly two types of ultrasonic meters- Doppler and transit time.
- Doppler ultrasonic flow meters: These can measure liquids with suspended solids, bubbles, and particulate matter. However, flow rate should be high enough to keep the particles and bubbles intact for flow meter to reflect ultrasonic signals. The shift in frequency is because of motion of particles and bubbles.
- Transit time ultrasonic flow meters: This type of flow meter uses a comparison of upstream and downstream measurements. This means it calculates the difference from time when ultrasonic signal is transmitted into pipe to the point the fluid moves out of pipe and is received by transducer. Most Sonic Pro flow meters by Blue-White use the transit type method. The Sonic Pro ultrasonic meters by Blue-White come in a NEMA-certified housing and have NSF 61 certification.
Cannon Water Technology also offers Seametrics level sensors. These are also ideal for flow monitoring applications. Seametrics level sensors record the level, time, and temperature of any water body such as a wet land, lake, or water pipes and industrial tanks in various applications. They are made of 3169 stainless steel and come with Modbus RTU protocol for increased connectivity.
Common Features of Ultrasonic Flow Meters
Ultrasonic flow meters, whose measuring principle for ultrasonic sensor or meters is either Doppler or transit time, are equipped with several noteworthy features. A few of them include:
- Non-Intrusive: One prominent feature of portable ultrasonic flow meters is they do not require direct contact with the flowing medium. In other words, they are non-intrusive, minimizing the risk of contamination or pressure drop.
- High Accuracy: These ultrasonic water flow meters offer precise measurements with minimal error. This high accuracy range guarantees reliable data for applications.
- Data Logging and Communication: Most flow meters are designed with data logging capabilities. This allows for the storage and analysis of flow data over a period of time. A few models are also equipped with communication interfaces for real-time data transmission.
- Bidirectional Flow Measurement: Certain ultrasonic flow meters have the ability to measure flow in both directions, enabling bidirectional flow measurement. This capability proves especially valuable in applications where the flow can reverse, such as water distribution systems.
- Wide Flow Range: Our range of handheld ultrasonic flow meter possess the capability to accurately measure flow rates, from low and high velocities. Given this versatility, these devices find applications in several instances, ranging from laboratory settings with modest scale to extensive industrial operations.

FAQ:
- How does an ultrasonic flow meter work?
Ultrasonic flow meters operate on the principle of measuring the time it takes for ultrasonic waves to travel between two transducers. One transducer emits ultrasonic waves, and the other receives them. By measuring the difference in travel time in the upstream and downstream directions, the flow velocity and flow rate of the fluid can be determined.
- What are the advantages of using ultrasonic flow meters?
Ultrasonic flow meters offer several advantages, such as non-intrusive measurement, no pressure drop, wide turndown ratio, high accuracy, minimal maintenance requirements, compatibility with various fluids (liquids and gases), and the ability to measure bi-directional flow. They are also unaffected by the fluid's conductivity, density, or viscosity.
- What Range of Pipe Diameters Can Ultrasonic Water Flow Meter Measure?
The handheld ultrasonic flow meter can measure a wide range of pipe diameters. It is wisely designed to accurately measure the flow rates in pipes of various sizes, ranging from small-diameter pipes to large-diameter pipes. Being said this, the exact range of pipe diameters that can be measured depends on the specific model of the ultrasonic flow meter used for the application. However, generally, these meters are capable of measuring pipe diameters as small as ½ inch to 48 inches.
- Are ultrasonic flow meters suited for dirty and clean fluids?
Ultrasonic flow meters are suited for both clean and dirty fluids; however, you must be careful about the type of device you choose for your application. For instance, transit-time flow meters are suited for clean fluids with low levels of contaminants; however, Doppler flow meters are ideal for measuring dirty fluids.
