1. What are the flow meter products with similar accuracy to electromagnetic flow meters?
Flow meter products with similar accuracy to electromagnetic flow meters mainly include Coriolis mass flow meters, high-precision pipe section ultrasonic flow meters, and high-precision turbine flow meters.
1. Coriolis mass flow meters.
The accuracy range is ± 0.05% - ± 0.2%, and some high-end models can achieve an accuracy of ± 0.05%, which matches the conventional accuracy range of electromagnetic flow meters. 2. It can directly measure mass flow without being affected by factors such as temperature, pressure, density, viscosity, etc., and can also output density and temperature parameters at the same time, with a large range ratio. 3. Representative products include Emerson high-precision series and Xingao Technology XMC series (optional ± 0.05% accuracy). 4. It is suitable for trade handover of crude oil, finished oil, chemical raw materials, liquefied gases, as well as accurate proportioning and mass balance scenarios in scientific research. 5. The limitation is that large-diameter products have high cost and are sensitive to vibration and two-phase flow, requiring regular zero point testing. Calibration.2. High precision pipe section ultrasonic flowmeter 1 The accuracy range is ± 0.5% - ± 1.0%, which meets the conventional accuracy requirements of electromagnetic flow meters. 2. It has the characteristics of zero pressure loss and no moving parts, and can measure non-conductive liquids (such as oil), supporting bidirectional measurement. Lower.
III. High precision turbine flowmeter 1 The accuracy range is ± 0.5% - ± 1.0%, and some high-end models can reach ± 0.2%. The accuracy is comparable
2. What instruments and meters are the most expensive in chemical plants?
The most expensive instruments and meters in chemical plants are usually high-end reactors and complete analysis systems that integrate cutting-edge technology, have a high degree of automation, and precision analysis capabilities.
. After understanding the driving factors of price, lets take a look at which instruments stand at the top of the price pyramid. 1. High end laboratory synthesis reaction systems are the core of research and meticulous synthesis in chemical plants, with extremely high technological content. Mettler Toledo LabMax ™ The transaction price of a fully automated laboratory synthesis reactor is usually in the range of 500000 to 1 million RMB, which realizes a highly automated experimental process. The price of the Mettler Toledo EasyMax Advanced chemical synthesis reactor system ranges from 200000 to 500000 RMB, making it a powerful tool for meeting high-end chemical synthesis needs. 2. Precise online analytical instruments and complete chromatography systems are used for real-time monitoring of material composition in the production process, with extremely demanding requirements for accuracy and stability. Complete systems such as online near-infrared analyzers and online gas/liquid chromatographs are very expensive due to their need to be directly integrated into pipelines and withstand harsh operating conditions. Some imported high-end models can be sold for millions of yuan. Even second-hand Agilent liquid chromatography specific detectors (such as fluorescence detectors) are often priced
