Brief introduction
Vortex flow meter is an instrument that placing a non-streamlined vortex generating body in fluid to alternately separate the fluid in the body sides and release two bunches of regular staggered vortex, and the frequency of separating vortex is directly proportional to flow in a certain range. It is researched and produced based on the principle of the Karman Vortex Street, and has characteristics of high accuracy and small pressure loss. Our flange type vortex flowmeter (LF502) has better performance and functions.
1,It has the functions of resetting cumulative flow and recovering data.
2,Its backlight LCD can let users clearly read results under direct sunlight or in dim room.
3,It can display instantaneous flow, cumulative flow and alarm status.
4,Available rotated 90 degree around the display from the standard position to meet visibility requirement that a flow meter is installed in different location.
Performance Index
Accuracy: |
Liquid:± 0.75% of reading Gases and steam: ± 0.1% of reading Note: These values are the accuracy of pulse output, if there is analog output, the above values need to plus ± 0.15% of full scale. |
Repeatability: |
± 0.2% of indication |
Stability: |
± 0.2%/per year |
Effect of Environment Temperature: |
Has no effect on digital and pulse output For analog output, ± 0.15% of range(-25 ~ 85°C) |
Effect of Installation Location: |
When the instrument is installed in horizontal, vertical, or sloped pipe, it can meet accuracy index. |
|
Magnetic Interference: |
HART Analog: in the case of 30A/m, the output error is less than ± 0.15% of full scale, in line with the IEC60770-1984 |
Effect of Power Supply: |
HART Analog: less than 0.005% of full scale/ per volt |
