The wall mounted ultrasonic flowmeter consists of a main unit and an external clamp type sensor. Simply attach the external sensor to the surface of the pipeline to complete various liquid flow measurements. Compared with traditional flow meters, there is no need to cut off the pipeline and installation is fast, achieving non-destructive installation
Manufacturer of wall mounted ultrasonic flowmeter
The wall mounted ultrasonic flowmeter uses the velocity difference method as its principle to measure the liquid flow rate inside a circular tube. This series of instruments adopts low-power digital design technologies such as digital transmission, digital reception, digital analysis, and digital output. The instruments have accurate measurement, reliable operation, and are more suitable for the needs of industrial sites. Converter forms include: wall mounted, disk mounted, and integrated; The sensor forms include: plug-in, pipe segment, and external clamp.
The wall mounted ultrasonic flowmeter utilizes the principle of low voltage and multi pulse time difference, and adopts high-precision and ultra stable dual balanced signal detection and differential reception digital detection technology to measure the sound wave transmission time in the forward and reverse directions, and calculate the flow velocity based on the time difference. It has a very simple installation method, without breaking pipes or stopping water, allowing customers to easily achieve flexible measurement of pipeline flow. The product can also be equipped with installation fixtures, which do not require daily maintenance and provide reliable, drift free measurements over the long term. It adopts advanced digital correlation technology and intelligent adaptive sound wave technology, which makes its measurement stability more outstanding. At the same time, its sound focusing technology significantly enhances the signal reception quality of the product during continuous measurement.
Advantages of wall mounted ultrasonic flowmeter products
Micro power consumption and digital design: The whole machine adopts micro power consumption hardware and software design to digitally transmit, receive, and analyze ultrasonic signals, achieving comprehensive digital design with a power consumption of less than 0.3W. The battery powered machine has a power consumption of only 0.2mW.
Excellent measurement and management functions: Scientific analysis and calculation techniques are adopted in software design to ensure accurate measurement functions. In addition, management functions have been designed, and this series of instruments can access instrument operation data from any time in the previous decade at any time.
Flexible maintenance performance: Adopting commutation adaptive technology, this series of instruments can automatically eliminate zero point errors in the measurement process, and can replace converters and sensors arbitrarily during maintenance without affecting measurement accuracy.
Hanization technology: The data input and measurement process of the instrument are displayed in Chinese characters, allowing the operator to operate without using the manual.
Plug in ultrasonic flowmeter: can be installed and maintained without stopping production. Using ceramic sensors and our company’s dedicated drilling device for non-stop installation. Generally used for monaural measurement, in order to improve measurement accuracy, three channels can be chosen.
Pipe section ultrasonic flowmeter: It needs to be installed by cutting open the pipeline, but maintenance in the future can be carried out without stopping production. You can choose between mono or tri channel sensors.
External clamp type ultrasonic flowmeter: capable of completing fixed and mobile measurements. Install using specialized coupling agents (room temperature cured silicone rubber or high-temperature long-chain polymer grease) without damaging the pipeline during installation.
