Description
ST502 Clamp-On Ultrasonic Flow Meter for Hot Water
Product Overview

The ST502 Ultrasonic Flowmeter utilizes transit-time methods to measure liquid flow in industrial systems, delivering high-accuracy flow data through clamp-on transducers that never contact the fluid.

Key Features
  • Measures actual flow and total consumption of various liquids
  • CNC machined process with magnetic open cover technology
  • Adaptive signal processing algorithms for challenging flow conditions
  • Clear LCD display with alarm function and easy operation
  • Bidirectional flow measurement using transit-time ultrasonic technology
  • Built-in 2G SD card for historical flow data analysis
  • Simple menu system for fast configuration
Measurement Principle - TVT Technology

TVT (Transit-Time Vortex) technology combines transit-time ultrasonics with vortex shedding phenomenon, delivering unparalleled accuracy and versatility in ultrasonic flow measurement.

The device uses ultrasonic transducers installed on the pipe exterior. One transducer sends pulses downstream with flow, while the other sends upstream against flow. The time difference between signals is proportional to flow velocity.

Installation Methods
V Method
Standard method providing accurate readings for pipe diameters 25mm to 400mm (1"~16"). Requires proper transducer installation at pipe centerline with equal spacing.
ST502 clamp on ultrasonic flow meter hot water
Z Method
Utilizes directly transmitted signals with less attenuation. Suitable for pipe diameters 100mm to 3000mm (4"~120").
ST502 clamp on ultrasonic flow meter hot water
N Method
Sound waves traverse fluid twice and bounce three times off pipe walls. Suitable for small pipe diameters, improving accuracy by extending transit distance.
ST502 clamp on ultrasonic flow meter hot water
W Method
Sound waves traverse fluid four times and bounce four times off pipe walls. Suitable for very small pipes (diameters less than 50mm, 2").
