Description

Technical Field

[0002] A flow meter that can be installed under pressure is a device used to measure the flow of liquid or gas. It is designed to measure the flow rate and flow rate of the fluid in a pipeline while allowing a certain pressure to be maintained in the fluid pipeline. Depending on the type of flow meter, the working principle can be different. Common ones include electromagnetic flow meters, ultrasonic flow meters, vortex flow meters, etc. When the fluid passes through the pipeline, the flow meter measures the flow based on the characteristics of the fluid such as velocity, pressure or sound waves. It means that the flow meter can work in the fluid pipeline while maintaining a certain pressure in the pipeline. The design takes into account the pressure in the pipeline to ensure that the structure of the flow meter can withstand and adapt to the working pressure in the pipeline to prevent leakage or damage. It is commonly used in chemical, petroleum, pharmaceutical and other industrial fields to monitor the fluid flow in the production process to ensure production efficiency and quality, such as water supply pipelines, sewage treatment plants, etc. It is used to monitor and control water flow, as well as for resource management and environmental protection. It is used for flow monitoring and management of gas pipelines, oil pipelines, etc. to ensure safe operation and resource utilization.
