Clamp-on type ultrasonic energy meters that use transit-time methods to measure flow.

ST501 Ultrasonic Energy meter uses the most reliable digital signal processing technology, transmitting flow measurement for a wide range of liquid and pipe sizes with high accuracy and reliability. Combined with outstanding performance transducers and higher industrial level materials, Flo-Instruments ensures long-term operation without concerns.

Clear menu display selections make instrument use very convenient. Clamp-on transducers provide flexibility across a wide range of applications.

The ST501 ultrasonic Energy Meter is based on Transit-Time technology, which delivers high measurement accuracy. Using clamp-on transducers, the ST501 collects flow data simply by clamping onto the outside of the pipe, never contacting the fluid, and avoiding liquid pollution, pressure reduction, leakage, and other issues.

TVT (Transit-Time Vortex) technology represents a cutting-edge approach to ultrasonic flow measurement, combining transit-time ultrasonics with vortex shedding phenomenon capabilities, delivering unparalleled accuracy and versatility in ultrasonic flow meters. This innovative integration technology enhances accuracy, versatility, and performance, making these meters well-suited for a wide range of applications across various industries.

The device features a pair (or more) of ultrasonic transducers installed on the exterior of the pipe (clamp-on) or inserted in-line. One transducer sends an ultrasonic pulse downstream with the flow, while the other sends it upstream against the flow. Since fluid movement affects ultrasound transit time, the time difference between signals is directly proportional to flow velocity.

The ST501 Fixed Ultrasonic Flow Meter is equipped with multiple communication and output options to ensure seamless integration into various industrial control systems. These outputs enable real-time data acquisition, remote monitoring, and control of flow-related processes.
