Can a steam mass flow meter be installed behind the control valve? Which type of flow meter is accurate?

It deals with steam mass flow meters that operate on the Coriolis principle; these meters work in conjunction with a control valve to maintain a constant steam flow in the pipeline. Is there any specific order required for installing these two components? Generally, control valves are installed behind flow meters to prevent fluctuations in the control valve from interfering with the metering process. However, Coriolis flow meters do not require straight pipe sections before or after them; does this mean it doesn’t matter whether the control valve is installed in front or behind the flow meter? As a follow-up, what do you think are the best flow meters for measuring steam mass flow rate? I used to opt for vortex flow meters with temperature and pressure compensation, but the measurement results didn’t seem very accurate; later on I switched to mass flow meters.

The flow resistance caused by the necking of the mass flow meter is quite high; it seems that placing it in front of the control valve would result in less impact.

Using a mass flow meter where a control valve is already present is a bit excessive, isn’t it?

It’s possible, but it’s better to place the control valve at a greater distance...

What do you mean by a smaller impact? The goal of this process is to accurately measure the steam flow rate.

To measure steam flow, what type of flow meter is suitable? Spinning vortex – I’ve tried this before; it’s necessary to convert pressure density in order to determine the mass flow rate, but it doesn’t seem very accurate
