Ultrasonic flow meter is an advanced flow measurement instrument that plays an important role in many fields.
1. Measurement principle
It uses the propagation characteristics of ultrasound in fluid to measure flow. The ultrasonic transducer emits an ultrasonic signal that propagates in the fluid. When the fluid flows, the speed, time, phase or frequency of ultrasonic propagation in the downstream and upstream directions will be different. By accurately measuring these differences, combined with relevant parameters such as the diameter and material of the pipe, and calculating based on complex mathematical models, the flow rate of the fluid can be obtained and the flow value can be finally determined.
2. Main advantages
High precision
It has highly accurate flow measurement capabilities with a very small error range. This enables it to provide reliable data and ensure the accuracy of the production process in occasions with demanding flow accuracy, such as precise batching in chemical production and coolant flow control in high-end manufacturing.
Applicable to a variety of fluids
It can measure liquid flow, such as various industrial water, oil, etc., and gas flow, such as natural gas, compressed air, etc. Whether it is a clean fluid or a fluid containing certain impurities, it can be effectively measured.
Easy installation
Ultrasonic flow meters are mostly installed by external clamping or plug-in installation. The external clamping type does not need to destroy the pipeline structure and can be directly fixed on the outer wall of the pipeline; the plug-in installation is also relatively simple, with less changes to the pipeline system, which greatly reduces the difficulty and cost of installation, and is also convenient for later maintenance and repair.
3. Application fields
In the industrial field, it is widely used for flow monitoring in industries such as petroleum, chemical, and electric power; in municipal engineering, it is used for flow statistics of urban water supply and drainage systems; in the field of environmental protection, it can monitor the flow of waste gas and wastewater, and help the implementation of energy conservation and emission reduction.
