Split type electromagnetic flowmeter
The split type electromagnetic flowmeter is composed of two parts: electromagnetic flow sensor and electromagnetic flow converter. The sensor is mounted on the pipe to detect the flow of the fluid, and the converter is responsible for converting the signal of the sensor into a readable flow value. This structure makes the installation and maintenance of the instrument more convenient, while also reducing the resistance of the fluid flow, which is suitable for the flow measurement needs of different processes. one

Why can't we choose the vortex flowmeter diameter according to the process pipe?
Vortex flowmeters have been debugged and calibrated before leaving the factory, and the flow coefficient of each instrument is not the same. Therefore, in the selection should be based on the flow range provided by the manufacturer (generally m3/h) to determine the instrument caliber, when the measured medium conditions and the conditions provided by the manufacturer do not match, especially when the medium density and viscosity do not match; The lower limit flow rate should be determined by calculation, and t

Flow rate is an important parameter in natural gas production. Flow rate is the amount of fluid passing through a certain cross-sectional area per unit time. Flow is divided into instantaneous flow and cumulative flow. Instantaneous flow refers to the amount of fluid flowing through a section of the pipeline in a unit time, referred to as flow. Cumulative flow refers to the sum of the number of fluids flowing through the pipeline in a certain period of time, that is, the cumulative value of the instantaneous flow
