ST502 Clip-on Ultrasonic Flowmeter
Ultrasonic flow meters that use transit-time methods to measure flow.
Introduction
ST502 Ultrasonic flow meter use the most reliable digital signal processing technology, transmitting flow measurement for a wide range of liquid and pipe size with high accuracy and reliability. Combined the outstanding performance transducer with higher industrial level material, Flo-Instruments could have long time work without any worries.
Clear menu display selections make using instruments very convenient. Clamp-on transducers makes the unit more flexible over a wide range of applications.
The ST502 ultrasonic flowmeter is based on Transit-Time technology, which has high measurement accuracy. ST502 uses an clamp-on transducer, which can collect flow data simply by clamping it on the outside of the pipe, and it will never come into contact with the fluid, and will not cause liquid pollution, pressure reduction, leakage, etc.
Benefits
ST502 is a brand-new high-end product that is made of aluminum alloy material and realizes CNC processing method. It adopts the industry-leading full-sealed iron-absorbing side-opening technology without any screw locking, and the tedious steps of screwing are reduced. Such a convenient design truly realizes "one-second opening".
Principle
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 is 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.
Flo-Instruments ST502 ultrasonic flowmeter offers high-accurate and repeatable flow measurement for liquids at an economical price. It is made of strong metal case. Combined the outstanding performance transducer with high industrial grade material, it's ideal for pipes size from 1''(25mm) up to 200''(5000mm) in diameter. IP68 sensors that are easy to install requires this pipe not to be cut, thus reducing installation and labor costs. Simple interface makes it very convenient to operate.
