Product Description

vortex flowmeter

The Vortex Flowmeter is a high-precision flow meter suitable for measuring various fluids including steam, gas, and liquids. With a dual-detection design and proprietary algorithms, it offers superior measurement accuracy with a precision of 1.5% RD and a turndown ratio of up to 1:30. The digital signal spectrum analysis technology provides a broader measurement range and higher accuracy, while the intelligent digital display allows for monitoring of temperature, pressure, and cumulative quantities. This flow meter is widely used in mechanical manufacturing, electronics, food, metallurgy, chemical, pharmaceutical, textile, water treatment, and more. It can detect compressed air consumption, measure steam and gas flow and consumption, monitor industrial gas extraction flow, and measure liquids such as pure water and fuel. The Vortex Flowmeter's unique design and software algorithms ensure measurement stability and precision, making it a convenient and reliable choice for various applications.

Specification

Five advantages of the Hualiu digital intelligent vortex flowmeter over traditional flowmeters:

1. Ultra-wide range
This steam flow meter is engineered for exceptional performance, offering a measurement range from 5.5m/s to 60m/s. It guarantees accuracy between 7m/s and 60m/s, ensuring precision in every reading. Note, however, that flow rates exceeding 70m/s are beyond its measurement capacity.
The Hualiu digital intelligent vortex flowmeter is distinguished by its remarkable sensitivity, capable of accurately measuring flow velocities as low as 2m/s and extending its upper limit to an impressive 120m/s, all while delivering high-precision results.

2. Independent technology
Pioneering the industry with our unique dual detection design and proprietary software algorithms, Hualiu guarantees unparalleled stability and precision in each measurement.

3. Easy installation
Our integrated temperature and pressure design eliminates the need for pipeline drilling to install sensors, and negates the requirement for secondary meter instrument boxes. This revolutionary approach reduces construction efforts to just 1/4 compared to traditional steam flow meters, significantly cutting down installation costs.

4. Easy to use
Equipped with an optional 4G module, this flowmeter connects seamlessly to the Hualiu Smart Heating Network Monitoring System, enabling remote reading and management via PC or mobile app. This innovation drastically minimizes the workload of on-site specialists. Users can effortlessly access usage records online, ensuring transparent and fair billing processes. Moreover, owners benefit from flexible server and SIM card options, with Hualiu offering complete software system setup. Alternatively, users can opt for the complimentary cloud platform and mobile app software provided by Hualiu.
 5. Connection method
Offering versatile connection options: pipe flange connection, pipe plug-in connection, pipe thread connection, and pipe clamp connection, tailored to meet diverse installation needs.
