Process Engineering Division – Instrumentation and Automation Section – Daily Question – Question from 2020-11-09: Discussion question: 291. If a flow rate can be measured either using a throttling device or an ultrasonic flow meter, how would you make your choice?
I need to consider which flowmeter will still work well in extreme situations.
Vortex streets and throttling can affect the equipment upstream and downstream, leading to localized pipe blockages
Depending on the specific process conditions, metal rotameters are definitely used for low flow rates, while vortex flowmeters are considered for higher flow rates to achieve better accuracy
If a flow rate can be measured either using a throttle device or an vortex flow meter, then the vortex flow meter should be chosen when high accuracy in flow measurement is not required. Throttling devices are used for measurement when high precision is required.

Using a vortex flow meter instead of a orifice plate flow meter in flow measurement saves both money and effort.
