Measurement of steam
Thread Content
What kind of measurement and metering instruments are better for steam pipelines above DN300?
That depends on whether you are using it for settlement or process control. If you want to settle, use Vortex Street. Just use an orifice plate for process control, and the price is not high!
We use a vortex flowmeter with temperature and pressure compensation, and it seems to be working well.
For such a large pipe, it may not be suitable to use a vortex street. If the temperature and pressure are not high, you can consider using annubar, etc.
Nozzle or orifice plate is sufficient, V-cone is also acceptable
The insertion vortex flowmeter should be okay!
General use of Kong class； If the requirements are high, you can use ROSMENT's integrated flow meter.
Split vortex flowmeter with temperature and pressure compensation
Orifice plate + differential pressure transmitter + secondary instrument.
Either integrated vortex flowmeter or integrated orifice flowmeter is available.
For knowledge in this area, please refer to: Design of Steam Flow Measurement System - Design of Steam Flow Measurement System in "China Metrology" Issue 07, 2005. The system consists of a Verabar flow probe, a differential pressure transmitter, a pressure transmitter, a temperature element and an intelligent flow totalizer.
