Nonwoven also call filter pocket, Nonwoven is processed to multi-layer with advanced automatic welder, and there are three layers: One is coarse fiber to collect the big particles; The second is to collect small particles. The outside layer is reinforcing the effect. The advance structure design increase nonwoven performance and avoid any leakage under wind pressure on filter bag, inside screen can avoid the pockets join together and refine the leeward area, decrease the resistance, increase the dust holding capacity. The enhanced pocket is three-dimensional helical structure which can decrease the resistance by 30%. The performance is stability, the nonwoven media is washable. Dust collecting is 2.5times of the media, the temperature is< 85 the width is 0.6-0.75, the length is upon customer's requirement.

1, the fluid temperature changes on the flow coefficient of the vortex flow meter causes, the fluid temperature changes, the corresponding change in density, and thus differential pressure flowmeter and speed flowmeter mass flow measurement error, can be Density compensation to solve. In addition to this, changes in the temperature of the fluid also cause changes in the geometry of the measuring part of the flowmeter and therefore cause errors.
2. The flow coefficient is influenced by the temperature of the fluid and consists of two parts: the change in the width of the generated body and the change in the internal diameter of the pipe. Why do you say so? The Karman vortex street frequency is inversely proportional to the occurrence of the body. When the fluid temperature rises, the body increases, and the frequency inversely decreases, so the indication value is low; the flow coefficient is inversely proportional to the inner diameter of the pipe, and the fluid temperature increases. As the inner diameter of the pipe increases, the flow cross-sectional area on both sides of the generating body increases, the flow coefficient decreases accordingly, and the flow rate indication is low.
