Electromagnetic flowmeter model selection basis

Model selection based on the electromagnetic flowmeter, electromagnetic flowmeter is widely used in many manufacturing industries, especially in chemical industry, companies choose the equipment specifications to be able to according to the specification to undergo the instrument specifications, the specification detailed requirements must consider the instrument selected application conditions, if the goal of measuring requirements first, instrument measuring target mainly contains pure gas, steam, liquid medium, etc., not pure substance will cause the instrument damage, reduce instrument application time.

Measuring the velocity of the target of minimum liquidity and viscosity must be kept in the range of the corresponding electromagnetic flowmeter is usually used for the measurement of liquid directly, only some special liquid instrument measurement, if liquid minimum liquidity rate reached 0.5 meters per second, gas liquid rate reaches 4 meters per second or 5 meters per second, then can apply instrument measurement.

Other measurement objectives the amount of normal fluidity must be one half or two thirds of the measuring range of the meter.The diameter of the measuring instrument need not be too large, usually the diameter of the instrument is inversely proportional to the coefficient, the larger the diameter, the lower the instrument coefficient, the lower the vibration frequency pixel of the measurement target, the larger the deviation of the measurement data may occur, so it is best to choose the instrument with a smaller diameter when the company chooses the instrument.

The shrinkage diameter of the electromagnetic flowmeter need not be too large. The shrinkage diameter will improve the material flow rate, and bring greater resistance and back pressure, which is very prone to holes.The measured target temperature should not be too high, if want to prolong the application time of instrument parts, try not to run in the environment with higher temperature, will affect the application time of instrument parts, if there are pulsating flow material and rotating flow material, the existence of two kinds of material, cannot directly apply the instrument.

Porcelain city Shanghai instruments co., LTD., founded by former Siemens MrStone senior engineers, specializing in high quality, high precision, wide measurement range of the flow meter of the research and development and production work, independent research and development of our products enjoys a high reputation in the industry, small flowmeter development make up the blank of domestic small flow meter, the quality of the product can completely replace the Max, KRACHT (clark), OVAL and other international brands.
