Products Description
A fixed ultrasonic flowmeter is a type of flowmeter that uses ultrasonic waves to detect the flow state of fluids. It usually consists of ultrasonic sensors and host equipment. Ultrasonic sensors can measure the flow velocity and flow rate of the fluid through ultrasonic measurement, and transmit these parameters to the host equipment for processing and display. The product adopts a windowed software design, where all input parameters, together with setting and displaying measurement results, are subdivided into more than 100 independent window representations. Users can access specific windows to achieve the purpose of inputting parameters, modifying settings, or displaying measurement results. The windows are numbered with two digits (including the+sign), ranging from 00 to 99, followed by+0,+1, and so on. Window number, also known as window address code, represents a specific meaning.
