Electromagnetic flowmeter selection

Electromagnetic flowmeter selection, electromagnetic flowmeter motor selection, electromagnetic flowmeter is a measurement of the total flow of conductive medium measurement dashboard, electromagnetic flowmeter selection must understand the two factors, the following detailed introduction of the electromagnetic flowmeter selection.

Advantages of electromagnetic flowmeter: no throttling components, so the pressure damage is small, reduce energy consumption, only related to the average velocity of the measured flow body, measurement range is wide;Only after the water calibration can be measured other media, without adjustment, the most suitable for the liquidation of metrological verification equipment application.Because of the constant improvement of technical and process materials, stability, linear, and the improving of the precision and service life and the tube through the development of measurement for solid-liquid two phase medium chose removable electric level and scraper electric level, the method of dealing with the high pressure (32 mpa), corrosion resistant, anti alkali, alkali lining) medium measurement problem, and the diameter of the continuous development of large (3200 mm), the continuous improvement of service life (generally more than 10 years), the use of electromagnetic flowmeter to get more and more common, its cost is also reduced, but the overall price is very is fill of the price is still high,Therefore, it has a key influence in the purchase of flow meter.

1. Precision grade and function select the accuracy grade of the instrument panel according to the measurement regulations and the place of use to ensure economic development.For example, sites used for trade settlement, commodity handover and energy measurement should be selected with a higher accuracy level, such as class 1.0, class 0.5 or higher;As a place for process management, different precision levels are selected according to the operation regulations;Some are just to check the total flow of the whole process, do not need to do precise manipulation and metrological verification of the place, can choose a slightly lower level of accuracy, such as 1.5, 2.5, or even 4.0, at this time can choose the best and cheap plug-in electromagnetic flowmeter.

2. When measuring the flow rate of medium, measuring range of instrument panel and diameter of medium, the total flow rate of electromagnetic flowmeter can be used in measuring the flow rate of medium within the range of 0.5-12m /s, and the scope is relatively wide.Select dashboard specifications (diameter) is not necessarily and machining process piping, the same shall consider measurement is in the range of velocity determine traffic category, namely when the pipe line velocity of slightly lower, do not consider the provisions of the flow meter or again, when the velocity measurement precision can't ensure the dashboard must be smaller diameter, and flow velocity in the riser, a satisfactory measurement results.

Shanghai chinxi instrument co., LTD. Is a family enterprise, engaged in the development and production of high precision flowmeter, which can be applied to almost any pump.In order to guarantee the after-sale service and the price, cancel the intermediate agent, and keep close contact with the end customer and the market, the quality of the flowmeter has reached the first-class level in the world.
