Flow meters are instruments used to measure the rate of flow of liquids or gases. They typically consist of a pipe and a measuring device. As the fluid flows through the pipe, the flow meter can calculate the flow rate by measuring the time it takes for the fluid to pass and the pressure difference within the pipe. Flow meters can be used for various applications including industrial process control, environmental monitoring, fluid transportation, and laboratory research.

In the face of major disasters, how to quickly and accurately find the vital signs buried in rubble, concrete, and other rubble, and to maximize the rescue of the lives of trapped people has always been one of the technical problems in disaster relief work. At the beginning of last year, the Fire Bureau of the Ministry of Public Security issued a research project focusing on "Ultraviolet Broadband Radar Life Detector", which was jointly developed by the Provincial Fire Corps and Hunan Huano Star Electronic Technology Co., Ltd. Aiming at some major technical flaws in the current audio, optical, infrared and other life detectors, researchers have overcome a series of key technologies and adopted the new system of ultra-wideband radar technology to achieve rapid search and accurate positioning of living bodies. The test results show that the device can effectively detect human body activity and heartbeat, breathing and other activities within 20 meters.
It is understood that this equipment passed the seismic simulation test of the National Earthquake Administration in April this year. Subsequently, in Yushu earthquake rescue mission, rescue personnel successfully used this equipment to detect and rescue many people. Experts believe that the equipment is technologically advanced in China.
There are several types of flow meters, including turbine flow meters, electromagnetic flow meters, ultrasonic flow meters, and differential pressure flow meters, among others. Each type of flow meter has its specific advantages and range of applications. For example, turbine flow meters are suitable for measuring the flow rate of low-viscosity liquids, while electromagnetic flow meters are suitable for measuring the flow rate of conductive liquids.
Flow meters play a crucial role in many industries. In industrial settings, flow meters can help monitor and control the flow of liquids or gases in production processes. In environmental monitoring, flow meters can be used to measure the flow rates in wastewater and air emissions to ensure compliance with environmental regulations. In laboratory research, flow meters can be used to measure the flow rates of liquids or gases in experiments for accurate data analysis and experimental validation.
Hunan Radar Life Detector formally passed national scientific and technological achievement appraisal
The expert appraisal committee headed by He Jishan, an academician of the Chinese Academy of Engineering, identified the "Ultraviolet Ultra-Wideband Radar Life Detector" developed by the Hunan Provincial People's Government, which officially passed the national scientific and technological achievements appraisal.
