Weld Gas Totalizer

[Corlub Speciality]

We are looking for a Gas Totalizer to monitor Argon Co2 Mix Gas Consumption on daily, monthly and yearly basis. The product needs to be fitted in 4" Pipe line. Please suggest good source, cost effective.

Pressure? Max and min

Flow rate? Max and min

Mechanical or electronic?

Fixed location or mobile?

Accuracy required?

Volumetric only or temperature and pressure corrected?

What did cost effective mean?

So many variables and multiple metering vendors.

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

Thermal dispersion flow technology works well with clean dry gas that has consistent blend or mix and therefore has a constant thermal conductivity value.

Many flow meters have a built-in totalizer, otherwise an output signal can feed a totalizer meter.

Vendors like Kurz, Thermal Instrument, FCI, Sierra, or others make either flow tubes or insertion style flow meters.

Your supplier can't provide you with totals?

 

[Corlub Speciality]

The Unit needs to measure only Flow Rate in LPM, Total Gas flown across the Gas Totalizer in Litre. No Temp and pressured to be measured. The unit will be fixed.

A Coriolis meter would be my first choice.
They measure true mass flow.
The flow is through a solid line with no obstructions.

P.E. Metallurgy, consulting work welcomed

If you only care about actual volumetric flow and don't need extreme accuracy, a simple positive displacement meter might suit. Without pressures and flow rates it's impossible to say more with certainty.

If this is only for monitoring purposes (ie not a fiscal meter), assuming upstream P and T are fixed, a gear meter is commonly used for volumetric flows - gives you high flow turndown of at least 100:1 with no loss in accuracy. Knowing P / T, you can then convert to some other standard condition ( scf or Sm3 etc)manually.
