overview

Ultrasonic flowmeter is a type of velocity flowmeter that uses the principle of ultrasonic time difference to measure the velocity of the medium and calculate the volumetric flow rate of the medium. It is mainly used to measure the volumetric flow rate of a single uniform liquid that can conduct ultrasonic waves; It is impossible to measure non-uniform liquid media and uneven pipeline materials. Ultrasonic flow meters can be classified into flange type, external clamp type, insertion type, etc. based on the structural form of flow sensors; From the display mode, it can be divided into integrated, wall mounted, handheld, portable, etc; Usually, there are conventional combination forms such as flange integrated, wall mounted, handheld, and portable ultrasonic flow meters.

The flange integrated ultrasonic flowmeter adopts a pipe section flow sensor, which has the characteristics of high accuracy, wide range ratio, no pressure loss, and simple installation. It is easy to operate and uses a magnetic rod for menu operation on the main interface, which can automatically remember historical data; Wall mounted ultrasonic flow meters are used for long-term online measurement of various liquids. The host is wall mounted, and the flow sensor is installed on the pipeline. There are multiple flow sensors to choose from, making it the most widely used ultrasonic flow meter currently; Handheld and portable ultrasonic flow meters are designed to improve the convenience of flow measurement and are often used for temporary testing. They are small in size and light in weight, usually using non-contact and external clip on sensors, and equipped with data storage SD cards for easy data uploading, statistics, analysis, etc. in the future. Portable ultrasonic flow meters can be equipped with a built-in printer, which can achieve instant and timed printing. The parameters are as follows:
