ST502 Wall-Mounted Ultrasonic Flow Meter is from DN 25~DN 5000

The ST502 Clip-on Ultrasonic Flowmeter utilizes transit-time measurement technology to deliver highly accurate and reliable flow data. Engineered with the most reliable digital signal processing technology, it supports a wide range of liquid types and pipe sizes. Combined with outstanding performance transducers and higher industrial-level materials, the ST502 is built for long-term, worry-free operation.

Clear menu display selections make using the instrument very convenient. Clamp-on transducers make the unit more flexible over a wide range of applications.

The ST502 ultrasonic flowmeter is based on Transit-Time technology, which provides high measurement accuracy. The clamp-on transducer collects flow data simply by clamping onto the outside of the pipe — it never comes into contact with the fluid, and will not cause liquid pollution, pressure reduction, leakage, or similar issues.

• Measures the actual flow and total consumption of various liquids.
• CNC machined process with magnetic open-cover technology — no screws required.
• Adaptive signal processing algorithms optimize performance, ensuring accurate measurements even in challenging flow conditions.
• Clear display interface and LCD display with alarm function — easy to operate and debug.
• Utilizes transit-time ultrasonic technology to realize bidirectional flow measurement by precisely measuring the time it takes for ultrasonic signals to transmit upstream and downstream.
• Built-in 2G SD card leverages storage capabilities to analyze historical flow data for system optimization.
• Built-in keypad and simple menu system for fast and easy selection of pipe diameter, pipe material, liquid type, and measurement units.

The ST502 is a brand-new high-end product made of aluminum alloy material using CNC processing methods. It adopts the industry-leading full-sealed iron-absorbing side-opening technology without any screw locking, reducing the tedious steps of screwing. This convenient design truly realizes "one-second opening."

TVT (Transit-Time Vortex) technology represents a cutting-edge approach to ultrasonic flow measurement, combining the principles of transit-time ultrasonics with the capability to harness the vortex shedding phenomenon, delivering unparalleled accuracy and versatility in ultrasonic flow meters. This innovative integration technology enhances the accuracy, versatility, and performance of ultrasonic flow meters, making them well-suited for a wide range of applications across various industries — a valuable solution for industries requiring precise flow measurements in varying flow conditions.

• Enhanced Accuracy in Turbulent Flows: TVT technology excels in applications where fluid flow conditions vary between laminar and turbulent. The incorporation of vortex shedding data enhances accuracy in challenging flow environments.
• Versatility in Fluid Types: TVT technology is versatile and suitable for a wide range of fluid types, including liquids with varying viscosities and densities.

Flo-Instruments ST502 ultrasonic flowmeter offers high-accuracy and repeatable flow measurement for liquids at an economical price. It is made of a strong metal case. Combined with outstanding performance transducers and high industrial-grade material, it is ideal for pipe sizes from 1″ (25 mm) up to 200″ (5000 mm) in diameter. IP68 sensors are easy to install and require the pipe not to be cut, thus reducing installation and labor costs. The simple interface makes it very convenient to operate.
