Selection of cryogenic liquid flow meters
Thread Content
Recently, as the equipment becomes larger and larger, the pipelines become larger and larger. When the diameter of the pipeline is larger than 250, it is difficult to select a flow meter for measuring liquids such as liquid oxygen, liquid nitrogen, liquid argon, etc. I would like to ask if you have any welded flow meters for liquid flow measurement. Reliable and imported. Do you have any experience measuring mass flow meters in this type of liquid? Can you tell us the manufacturer and model? In the past, vortex flowmeters were used, but when the diameter became larger, they were no longer weldable.
Have you ever used a vortex street to measure liquid oxygen? At such a low temperature, only orifice plates can be used, which are used in air separation cold boxes.
You can consult GE. They have ultrasonic flowmeters specifically designed for cryogenic liquid measurement.
Orifice plates are great and require little maintenance!
The orifice plate is also enclosed and integrated and welded directly into the pipe.
I have used a vortex street with liquid oxygen. Can you tell me what is wrong? I know that the orifice plate is integrally welded, but the pressure difference between the orifice plate is large. If the liquid is not supercooled, it is likely to vaporize, so use it with caution.
No, can such a low temperature be used in a vortex street? Since I have never used it like this before, I have this question. Could you please share your application experience with everyone?
Vortex streets can be used in cryogenic liquids, and the sensor must be separated from the transmitter, which is a split type. The transmitter is placed in a non-low temperature place. Be aware that the length of cryogenic cables is limited.
If the low-temperature large-diameter flowmeter is used for process control, you can choose a target flowmeter. We have achieved good results by using it on site, but of course it cannot be used for trade.
I use it to assess product flow, and I hope the accuracy can be higher. Can the person upstairs provide the manufacturer and model of the target flowmeter? Thanks

For low-temperature large-diameter flow meters, we can achieve an accuracy of 0.5. The connection method can be welding. If necessary, we can provide you with a measurement plan. Shenzhen Gessel Technology Pan Yi (15920397255)
For this working condition, you can choose the ultra-low temperature Wo Street mass flowmeter from SIERRA in the United States. The specific technical parameters are as follows: Accuracy------for liquids, 30: The range of 1 is plus or minus 1.0% (mass flow) and 0.7% (volume flow) of reading. Repeatability------The mass flow rate is plus or minus 0.2% of the reading, and the volume flow rate is plus or minus 0.1% of the reading. Stability------(more than 12 months) The maximum mass flow rate is 0.2% of the reading, and the volume flow rate can be ignored. Turndown ratio------30: 1 Medium temperature-------200~400 Pressure resistance index------commonly used 10000KPa, special up to 34500KPa
Personally, I think ultrasonic liquid level meter is one direction. You can consult manufacturers in this area.
Hello, how are you using the vortex flowmeter you use for liquid oxygen? Is it stable? Which manufacturer? What's the manufacturer's phone number?
