ST502 Wall-Mounted Ultrasonic Flow Meter for Metering at Irrigation Pumping Stations
ST502 Clip-on Ultrasonic Flowmeter

Ultrasonic flow meters that use transit-time methods to measure flow.

The ST502 Ultrasonic Flow Meter uses 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 operation without concerns.

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 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.

Key Benefits
  • 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 for easy operation and debugging
  • 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 tedious screwing steps. This convenient design truly realizes "one-second opening."

Operating Principle
Introduction to TVT

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.

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.

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 pipe sizes from 1" (25mm) up to 200" (5000mm) 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.
