Differential pressure type delta meter scale application considerations

by:Sincerity     2020-11-05
Abstract: the application of the delta and differential pressure type flowmeter scale note information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Delta matters needing attention of the application of the flowmeter based on our use of the more than two years experience in application of the products main problems should be paid attention to the following aspects: 1. Large diameter low velocity of flow measurement. Before choose the device should be measured medium parameters such as minimum flow,. More flow meter manufacturers choose model price quote you are welcome to inquire, here is the application of the delta and differential pressure type flowmeter scale considerations article details. Delta matters needing attention of the application of the flowmeter based on our use of the more than two years experience in application of the products main problems should be paid attention to the following aspects: 1. Large diameter low velocity of flow measurement. Before choose the device should be measured medium parameters such as minimum flow, working temperature and pressure, pipe diameter to provide accurate for the supplier, through manufacturer to calculate the minimum differential pressure after lower limit according to the measurement of the transmitter can meet the accuracy of measurement. 2. Used in the measurement of blast furnace and converter gas probe the hao add nitrogen purging piping, blast furnace in when the wind to blow, probe to ensure long-term operation. Measuring probe should be equipped with steam purging of coke oven gas tube, for the probe jams blow. But our factory for these two kinds of gas metering blocking phenomenon does not exist more than two years, blow pipe is only used as a backup. 3. Measurement for diameter 600 mm or more lines suggest choose double support, in order to prevent the deformation of probe in the runtime occur in a wide range and affect the accuracy of measurement. 4. When choosing the product must be the measuring tube diameter to provide accurate. Because design to probe to take pressure distribution is calculated according to the pipe center, pipe diameter, if there is a big error will cause the probe measured pipeline with different heart caused by the larger error of measurement. 5. For measuring meter Suggestions with full tube inserted into the probe, especially in the straight pipe does not satisfy the requirements should be like this. 6. As the delta flowmeter combat capability is strong, if the flowmeter installation of pipelines have the chance to stop gas maintenance within a year, does not need to choose and buy online insertion device, usually equipped with gas blow can ensure normal measurement for a long time, in order to save investment. 7. As a result of the coke oven gas velocity is small, the differential value of pipe diameter is large, usually only more than 100 mpa, Based on the standard conditions) The medium containing a certain amount of impurities, density of the measured medium than 0. 46 is larger, so the actual of differential pressure is larger than the theory of differential pressure; At the same time you need to use the high precision and high stability of the differential pressure transmitter. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
It isn't just about being on mass flow meter anymore–it's about maximizing the potential of the platform of manufacturing.
