Inline measurement of glycol in water

Inline measurement of glycol in water

(OP)
Dear All

We need to measure the inline consentration of glycol in water. The pipe size is 6" and the avg consentration is 30%. The temperature is 45 deg. C and 90 deg. C.
We need a 4-20 mA output and 24 vdc power supply.

Thank you for your help

RE: Inline measurement of glycol in water

The density of glycol and water are quite different and so a simple process density measurement will give you very good concentration measurement. A good densitometer will even include the temperature density referral to find the density at a reference temp for the solution from which to calculate the concentration. Glycol water data is well publicised on the web so setting up the system is relatively easy.
For a 6" line your best bet is an insertion density meter which installs in the side of the pipe and measures at your process conditions and gives you the results as %concentration.
You can search the web for density meters, densitometers, vibrational density meters etc or visit our web page.
