In the industrial process and energy measurement fields, the accuracy, stability, and reliability of flow measurement are of utmost importance. The fixed separation ultrasonic flowmeter, with its non-contact measurement, wide range, and high precision, has become the preferred instrument for many industries. This article will deeply introduce a fixed separation ultrasonic flowmeter with a model range from DN15 to DN6000mm, and thoroughly analyze its outstanding features and wide applicability.
I. Product Overview
This fixed separation ultrasonic flowmeter, launched by the HBM brand, is a precise measuring instrument based on the time difference principle. Its “fixed separation” design means that the converter (main unit) and the sensor (probe) are separate parts connected by a dedicated cable. This design enables it to be flexibly installed on pipes of different materials and diameters, especially suitable for applications where the process cannot be interrupted or where the pipe cannot be easily cut.
II. Core Advantages and Features
1. Outstanding High Reliability
Low Voltage Multi-Pulse Technology: This technology is the core for ensuring the long-term stable operation of the flowmeter. By emitting a series of low-energy pulse signals and analyzing and processing them, it effectively overcomes the influence of bubbles and impurities in the fluid, significantly improving measurement accuracy, extending the service life of the instrument, and ensuring the high reliability of the entire system.
2. Extremely wide measurement range
A variety of sensor types are available, and the measurement pipe diameter range is astonishingly wide, covering from DN15mm small pipes to DN6000mm large pipes. This unparalleled adaptability enables it to serve applications of various scales, ranging from fine chemicals to urban water supply, from factory workshops to large-scale water conservancy projects.
3. Strong anti-interference capability
By adopting dual balanced signal differential receiving/driver circuits, it can effectively suppress complex electromagnetic interference generated by equipment such as frequency converters, TV towers, and high-voltage lines, ensuring the purity of the signal and measurement stability in harsh industrial environments.
4. Powerful data recording and storage function
This flowmeter is equipped with a powerful data recorder that can automatically record:
Historical cumulative flow: Total data for the past 512 days, 128 months, or 10 years.
Event records: The time and corresponding flow of the latest 64 power-on/power-off events.
Operating status: The operating status of the instrument for the past 32 days.
Supports SD card storage: Users can choose to use an SD card for data export and extended storage, making it convenient for later data analysis and auditing.
5. Support for heat/energy measurement
By connecting a Pt100 temperature sensor, this flowmeter can be easily upgraded to an energy meter, directly measuring and calculating the heat or coldness transferred by the system. It is widely used in heating, air conditioning, and heat exchange systems.
III. Wide applicability
Pipe material: Almost unrestricted, including steel, stainless steel, cast iron, copper, cement pipe, PVC, aluminum, fiberglass reinforced plastic, etc., even pipes with inner linings can be applicable.
Installation requirements: To ensure measurement accuracy, the sensor installation position must meet the requirement of a straight pipe section of 10D in front and 5D behind (D is the pipe diameter), and the distance from the pumping station should be more than 30D.
Application industries: Municipal water supply, sewage treatment, petrochemicals, heating and cooling, food and beverage, metallurgy, papermaking, etc.
IV. Conclusion
Based on the above discussion, this DN15-6000mm fixed-separation ultrasonic flowmeter is a high-performance measuring instrument that integrates high reliability, wide range, strong anti-interference capability, and powerful data management functions. Its flexible non-contact measurement method, excellent adaptability to various media and pipe materials, as well as the optional heat measurement function, make it a highly competitive and practical solution in modern industrial flow measurement. Whether it is used for simple flow monitoring or complex energy management systems, it can provide precise and reliable data support.
