Ultrasonic flow meters are a type of electronic flow measurement device that can be used for many industries, including chemical processing, food and beverage, and water treatment. These devices are usually more expensive than inline flow meters, but they offer a number of advantages over other types of flow meters.
In this article we’ll go over some of the benefits of ultrasonic flow meters over inline flow meters:
Ultrasonic flow meters are more accurate than inline flow meters because they use a high-frequency ultrasonic wave to measure the speed at which fluid passes through the meter. The speed at which fluid flows through an inlet is calculated by the frequency of the ultrasonic wave, which is detected by a sensor on the opposite side of the inlet. This calculation is performed by a computer chip inside of the meter and provides real-time data about how much fluid is flowing through it.
Inline flow meters use a different method to calculate flow rates from velocity measurements taken from each side of an inlet using propellers or impellers attached to each side of an inlet that spin as water passes through them. These spinning propellers are read by a paddle wheel on each side of an inlet that measures how many times each one spins per minute (RPM). From this information, engineers can calculate how fast water flows through an inlet based on how many RPMs are recorded over time (RPM/min).
Ultrasonic flow meters are extremely accurate, with an accuracy rating on the order of one percent or less. This means that they can be relied upon to measure flows within a very narrow range of values. Inline flow meters are typically less accurate, with an accuracy rating around 5 percent or more. While this may not sound like much, it means that you could easily have an error in your readings anywhere from 0.5 percent to 5 percent! This can lead to inaccurate measurements which could then lead to improper water treatment processes or product quality issues down the line.
One of the main benefits of ultrasonic flow meters is that they are portable. They can be moved around the facility for testing or calibration purposes.
Ultrasonic sensors do not need to be removed from the water line when servicing the system. This makes them more convenient to use and less expensive than inline flow meters because they do not require any installation or maintenance costs after purchase.
