How Truflo Ultrasonic Flow Meters Work: A Comprehensive Guide by Icon Process Controls
Ultrasonic flow meters have become a popular choice for industries requiring accurate and non-invasive flow measurement solutions. Consequently, in this blog post, we will explore how ultrasonic flow meters work and highlight the Icon Truflo Ultraflo 500 series, a leading example known for its accuracy and durability.
Understanding the Operation of Ultrasonic Flow Meters
Ultrasonic flow meters operate on the principle of sending and receiving ultrasonic sound waves through a flowing liquid. Specifically, these sound waves are used to determine the velocity of the fluid. Consequently, when combined with the pipe’s dimensions, they allow for the calculation of the flow rate. So, here’s a step-by-step breakdown of how ultrasonic flow meters work:
Sound Wave Transmission:
The flow meter consists of two ultrasonic transducers—one serves as a transmitter, and the other as a receiver. The transmitter emits high-frequency ultrasonic sound waves into the flowing liquid.
Upstream and Downstream Propagation:
The sound waves travel in two directions: upstream (against the flow) and downstream (with the flow). The upstream waves move slower, while the downstream waves move faster due to the flow of the liquid.
By measuring the time it takes for the sound waves to travel from the transmitter to the receiver in both directions, the flow meter calculates the difference in transit time. Hence, this time difference is directly proportional to the velocity of the liquid.
Flow Rate Calculation:
The flow meter combines the measured velocity with the cross-sectional area of the pipe to calculate the volumetric flow rate. This data is then displayed on the flow meter’s screen or transmitted to external devices for monitoring and control.
