What type of flow meter is suitable for measuring liquid oxygen?
Thread Content
As the title suggests, the metering of liquid oxygen needs to be taken into consideration on the main pipeline used for unloading at the liquid oxygen station; since liquid oxygen is purchased from external suppliers, high accuracy in metering is required. Thank you
We have never used a flow meter to measure liquid oxygen; our liquid oxygen is billed based on weighing.
As a medium with unstable phase conditions, liquid ammonia typically exists in a two-phase state—gaseous and liquid—during transportation. Its density changes continuously, influenced by pressure fluctuations, which also affects its flow stability; therefore, it is not easy to measure its flow rate accurately. If lower precision is sufficient, vortex flow meters can be used. In China, vortex flow meters with good seismic resistance are now available, and proper temperature and pressure compensation will ensure accurate measurements. For trade-related measurements, weighing methods can be employed.
Weighing is used for settlement, while vortex flow meters are used for production control
The poster is asking about a flow meter for the accurate measurement of liquid oxygen; in fact, a mass flow meter can be used. However, it is important to ensure proper insulation and cooling for the flow meters on the liquid ammonia pipelines. Several major manufacturers of mass flow meters offer models designed for low temperatures; they can generally handle temperatures down to -200 degrees without any problems.
Vortex flowmeters are commonly used for liquid oxygen; they are suitable for low-temperature media, offer an accuracy of 0.5 grade, and are not resistant to vibrations
Which company supplies you with liquid oxygen? These days, it’s mainly done through weighing with scales for settlement; flow meters and things of that kind aren’t very accurate~~
We can use vortex flow meters; that’s what we do
