Regarding differential pressure flow, vortex shedding, mass, and electromagnetic flow – how can the measurement range be expanded?
Thread Content
If the designed range of a table is 0 to 100, and the current operating condition is 120, how can the measurement ranges of differential pressure flow meters, vortex flow meters for mass measurement, and electromagnetic flow meters be expanded? What considerations should be taken into account during this expansion?
This requires checking the technical documentation of the flow meter device currently in use; range expansion must be supported. It is advisable to consult the manufacturer, and if possible, it is recommended that professionals carry out the operation as well as manage the equipment changes.
For differential pressure and vortex flowmeters, it is necessary to calculate the parameter conditions in order to determine whether the measurement range can be expanded and by how much. As for electromagnetic flowmeters, they generally have a wide range of measurement capabilities; it is likely sufficient to reset the parameters within the device. Modern flow meters are basically intelligent; it is possible to expand their measurement range. However, when it comes to accuracy and pressure loss, especially in the case of differential pressure flow meters, it is necessary to calculate the differential pressure range as well. Therefore, the parameters of the meter must be recalculated before the measurement range can be expanded.
So how is it calculated? Differential pressure type, and vortex street type
