Measurement of bar flowmeter

Based on the principle of velocity difference method, the design characteristics of bar flowmeter are used to measure the liquid flow in circular steel tube. This series of instruments adopt the digital design scheme of digital transmission, digital reception, digital analysis, digital output and so on. The measurement verification and operation of instruments are reliable and more suitable for the requirements of industrial production on the spot. Converter mode: wall hanging type, plate antique type, integrated type; controller mode: plug-in type, pipe type, external clamp type.

Digital acceptance and digital analysis achieve the digital design scheme of * *, and the power consumption of the whole equipment is less than 0.3w. The power consumption of the whole equipment is only 0.1MW. ● micro power consumption and digital design scheme. The whole equipment adopts micro power hardware configuration and software development to carry out digital transmission of ultrasonic data signals

● extraordinary metrological verification and management methods. In the software development, the analysis and construction science are adopted to ensure the metrological verification function. In addition, the function of management method is designed. The instrument of this series can check the operation data of the instrument at any time in the first ten years at any time.

● convenient maintenance features. By adopting speed control response technology, the series of instruments can automatically eliminate the zero deviation in the whole process of measurement, and the converter and controller can be removed and replaced at will in the whole process of maintenance, without harming the measurement degree.

● technical. The data information of the instrument is input and displayed in the whole process of measurement, so that the operator can actually operate without using the manual.

● plug in ultrasonic flowmeter: installation and maintenance are not stopped. Adopt the porcelain controller, use the special punching equipment of our company to carry out the installation without stopping work. Generally, it is mono measurement, so as to improve the measurement degree, and three channels can be selected.

● pipeline type ultrasonic flowmeter: it needs to cut off the pipeline for installation, but the maintenance will not be stopped after that. Can choose mono or tri channel controller.
