ST502 Wall-Mounted Ultrasonic Flow Meter for HVAC

The ST502 ultrasonic flowmeter utilizes the most reliable digital signal processing technology, delivering flow measurement for a wide range of liquids and pipe sizes with high accuracy and reliability. Combined with outstanding performance transducers and higher industrial-level materials, Flo-Instruments ensures long-term, worry-free operation.

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

The ST502 ultrasonic flowmeter is based on Transit-Time technology, which provides high measurement accuracy. The ST502 uses a clamp-on transducer that collects flow data simply by clamping onto the outside of the pipe. It never comes into contact with the fluid, preventing liquid pollution, pressure reduction, leakage, and similar issues.

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 tedious screwing steps. 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 and a valuable solution for industries requiring precise flow measurements in varying flow conditions.

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.

TVT technology is versatile and suitable for a wide range of fluid types, including liquids with varying viscosities and densities.

The 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 pipes ranging from 1" (25mm) up to 200" (5000mm) in diameter. IP68 sensors are easy to install and require no pipe cutting, thus reducing installation and labor costs. The simple interface makes it very convenient to operate.
