What impact do highly viscous materials have on control valves, flow meters, pressure gauges, and similar devices in pipelines?

Could things like control valves get stuck and get damaged, and could the branches of the pressure gauge get blocked, resulting in inaccurate readings?
Yes, that’s why isolation devices must be used during measurement.
How does a control valve achieve isolation? The contact surfaces and seals are all located within the pipeline
The control valve isn’t the issue; I’m referring to measuring instruments, such as pressure gauges and pressure (differential pressure) transmitters – those devices that are used to measure pressure.
The control valve won’t do; I’m referring to measuring instruments that are used for taking pressure readings, such as pressure (differential pressure) transmitters and Bourdon tube pressure gauges.
It is recommended to choose V-type control ball valves, as their regulating performance meets the general requirements. The V-type ball valve has a cutout, which allows it to effectively shut off the flow of medium when closed. One of the most typical applications for V-type ball valves is in paper mills, where they are used in pipelines carrying fibers and where regulation or shutdown of the flow is necessary; in such cases, V-type ball valves are generally the preferred choice.
The V-ball or eccentric rotary valve is used in applications with high viscosity
