ST501 Insertion Ultrasonic Flow Meter for Wastewater Treatment Plants
Product Overview

The ST501 Insertion Type Ultrasonic Flowmeter utilizes transit-time methods to measure flow with high accuracy and reliability. Designed for a wide range of liquids and pipe sizes, this industrial-grade instrument combines outstanding performance transducers with robust materials for long-term operation in demanding environments.

Key Benefits
  • Measures actual flow and total consumption of various liquids
  • No process control loss, asset optimization, and no calibration downtime
  • Adaptive signal processing algorithms for accurate measurements in challenging conditions
  • Clear LCD display with alarm function for easy operation and debugging
  • Bidirectional flow measurement using transit-time ultrasonic technology
  • Data logging capabilities for historical flow pattern analysis and system optimization
  • Built-in keypad and simple menu system for fast programming
Measurement Principle

The ST501 employs advanced TVT (Transit-Time Vortex) technology, combining transit-time ultrasonics with vortex shedding phenomenon for unparalleled accuracy and versatility. This innovative integration enhances performance in varying flow conditions and is suitable for a wide range of fluid types, including those with varying viscosities and densities.

Applications

Insertion type ultrasonic flowmeters are primarily used to measure volume flow in conductive liquids and slurry in closed pipes, including acid, alkali, salt, and other highly corrosive liquids. Widely applied in petroleum, chemical, metallurgy, textile, food, pharmaceutical, paper-making industries, as well as environmental protection, municipal management, and water conservancy construction.
