ST501 Insertion Ultrasonic Flowmeter Designed for Harsh Environments with IP68 Transducer and Adaptive Signal Processing for Flow Data
ST501 Insertion Type Ultrasonic Flowmeter
Ultrasonic flow meters that use transit-time methods to measure flow.
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. The IP68 transducer is more suitable for applying in harsh environments such as humidity and immersion. Simple interface makes it very convenient to operate.
The ST501 ultrasonic flowmeter is based on Transit-Time technology, which has high measurement accuracy. Insertion transducer refers to inserting the transducer into the inside of the pipeline for flow measurement. It can accurately measure the flow rate and flow velocity inside the liquid pipeline. The advantage of the insertion transducer is that it can keep the outer surface of the pipe flat, thereby reducing pressure loss, and has high reliability and measurement accuracy.
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.
Flo-Instruments ST501 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 48''(1200mm) in diameter. Insertion transducer refers to inserting the transducer into the inside of the pipeline for flow measurement. It can accurately measure the flow rate and flow velocity inside the liquid pipeline. The advantage of the insertion transducer is that it can keep the outer surface of the pipe flat, thereby reducing pressure loss, and has high reliability and measurement accuracy.
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.
- 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.
Applications
Insertion type ultrasonic flowmeters are mainly used to measure volume flow in conductive liquids and slurry in closed pipes. Including acid, alkali, salt and other highly corrosive liquids. Insertion type ultrasonic flowmeters are widely used in petroleum, chemical, metallurgy, textile, food, pharmaceutical, paper-making and other industries, as well as environmental protection, municipal management, water conservancy construction and other fields.
