Vortex flow meters and Coriolis flow meters are used in parallel
Thread Content
In a recent project, it was originally planned to use an 8-inch Coriolis flow meter to measure the flow rate and density of the liquid. Later, the manufacturer found that the 8-inch Coriolis flowmeter was too expensive, so they planned to switch to an 8-inch vortex flowmeter for measuring volume flow, while connecting a 1-inch Coriolis flowmeter in parallel to measure density. Some colleagues believe that this approach will affect the measurement accuracy of vortex flowmeters. What do you all think? Is this a viable solution? What is the best approach?
It is possible to perform measurements at different locations (or with a sufficient distance between them), so that there will be no interference between them.
If the 1-inch Coriolis flow meter in bypass is placed upstream of the 8-inch vortex flow meter, should it be connected in parallel with a control valve or some manual valve in order to ensure that there is flow passing through the Coriolis flow meter (i.e., to maintain a differential pressure)?
An 8-inch Coriolis mass flow meter? Regardless of whether it exists or not, if it does, its price is likely to be no less than 1 million RMB per unit. Vortex flow meters can be used for measurement, as can throttle devices; parallel mass flow meters are not necessary – just use a density meter and that will solve the problem.
