Which measuring instrument is suitable for measuring steam in large-diameter pipelines
Thread Content
A steam flow meter should be installed on the 450 mm pipeline at the boiler room outlet; as alternatives, there are V-cone, orifice plate, and Yokogawa vortex flow meters. Which one do you think is the most suitable choice? Please feel free to share your experiences; I would be very grateful. :lol:victory:
The largest Yokogawa vortex street type is DN300, unless you can use one with a variable diameter. Use a V-cone or nozzle.
Ignoring the issue of maximum diameter, what are the advantages of installing nozzles? Actually, what we install at the customer’s site are vortex flowmeters – there are hundreds of them in total. Whether it comes to installation in the initial stage or maintenance later on, we still prefer to use vortex flowmeters. Thank you
Is the throttle element better, for superheated steam?
Vortex flow meters and orifice plates are more commonly used for measuring steam. A 450 pipeline can use a elbow flow meter.
The service life of the nozzle is longer than that of the vortex flow meter. The range of temperatures and pressures to which the nozzle can operate is also wider than that of the vortex flow meter. The nozzle is a standard component that does not require calibration, and it offers high precision as well
Does the poster need to purchase a flow meter? The flow meters produced by Weihai Wenrun Measurement and Control are also good; I hope you will consider them
For reducing temperature and pressure in one plant, Aniu flow meters are used, while vortex flow meters are employed for transporting the fluid to another plant
Reply: Bar-type flowmeters are the most suitable, as they are cost-effective for plug-in installation.

The original poster should specify the temperature/pressure (likely less than 16 BAR), the required precision, the flow rate range, and whether it is in a superheated or saturated state This is more targeted. For steam metering in factories, a throttle element combined with temperature and pressure compensation is generally sufficient to meet the accuracy requirements. Of course, it’s good to be able to make use of vortex street technology well (Yokogawa is indeed capable of doing that). For long-term use, a throttle element is more suitable as it has a longer lifespan. @jiaguoyun @WindHowling
If the accuracy requirement is not high, an orifice plate flow meter is a suitable choice
