Cost-Effective Fixed Ultrasonic Flowmeter ST501

Introduction

ST501 Ultrasonic flow meter uses 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 can have long time work without any worries.
Clear menu display selections make use of instruments very convenient. Clamp-on transducers makes the unit more flexible over a wide range of applications.
The ST501 ultrasonic flowmeter is based on Transit-Time technology, which has high measurement accuracy. ST501 uses a 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

• Measures the actual flow and total consumption ofvarious liquids
• No loss of process control, optimization of assets and efficiency, no downtime or expense from calibration
• Adaptive signal processing algorithms optimize performance, ensuring accurate measurements even in challenging flow conditions.
• Clear display interface and LCD display with alarm function, easy to operate and debug
• Utilize transit-time ultrasonic technology so as to realize bidirectional flow measurement by precisely measuring the time it takes for ultrasonic signals to travel upstream and downstream
• Leverage the data logging capabilities to analyze historical flow patterns to make system optimization.
• Built-in keypad and simple menu system for fast and easy programming of pipe diameter, pipe material, liquid type, and measurement units.

Principle

• Introduction to TVT

The Transit-Time Ultrasonic Flow Meter, also known as Time-of-Flight (TVT) ultrasonic flow meter, is a non-intrusive flow measurement technology widely used for clean liquid applications. It operates on the principle of measuring the time difference between ultrasonic signals transmitted in the direction of flow and against the flow direction.

The device has a pair (or more) of ultrasonic transducers installed on the exterior of the pipe (clamp-on) or inserted in-line. One transducer sends an ultrasonic pulse downstream with the flow, while the other sends it upstream, against the flow. Since the fluid's movement affects the transit time of the ultrasound, the time difference between the two signals is directly proportional to the flow velocity.
