Displacement flowmeter is an important measuring instrument in the chemical industry. In chemical production, the quantity of various raw materials is very important, which is related to production safety. If the ratio is not correct, accidents such as explosions may occur. Therefore, in the actual production process of the chemical industry, it is necessary to measure the flow of various media in real time, including the size, speed, volume and quality of the flow, so as to effectively ensure production safety. So, what types of flowmeters are there?
The development of displacement flowmeter is constantly improving with the actual production. At present, there are three main types of flowmeters, mechanical flowmeters, electronic flowmeters and turbine flowmeters. Mechanical flowmeters are one of the earlier ones. They are mechanical and have low accuracy when measuring. Moreover, due to the mechanical structure, they can only measure some specific media and have a narrow range of applications. Compared with mechanical flowmeters, electronic flowmeters have the widest range of applications. This flowmeter uses electronic technology to measure the flow of the medium, so the accuracy is higher than that of the mechanical type, and the measured data is more accurate and reliable. Its working principle is the magnetic measurement principle or the ultrasonic measurement principle, which mainly changes according to the different properties of the medium in actual applications. Turbine flowmeter is also very common. It is an electronic flowmeter. Its working principle is to measure the turbine speed and infer the medium flow rate through the turbine speed. The advantages of this measurement method are high accuracy and fast response speed. Its disadvantage is that it has requirements for the properties of the medium and is not suitable for overly viscous media, because the viscosity of the medium can easily affect the turbine speed, thereby affecting the measurement accuracy.
The current flowmeter still has some problems in practical applications, but the displacement flowmeter is still an important tool in chemical production.
