Hi All, 

Hope you're all doing well. 

I'm a chemical engineer and am new in this forum. 

Currently, I am calculating the corrosion inhibitor availability using the difference in the tank levels that are measured using level transmitters (magnetic level indicators). I tried to compare the level transmitter values with the level gauge values and they showed a difference ranging between 28 L and 81 L. I'm not sure which one is more accurate. However, high corrosion inhibitor availability is required in this system and inaccuracies in the measurements are really undesired.

Have you encountered such differences between level transmitter and level gauge readings? which one is more reliable? what are the possible reasons? and how to rectify? 


I appreciate your responses. 

Many thanks,
Bal.

Hi ,

what is the reference ? 28 l or 81 l compared to 1000 liters or 10 000 l!!!!

is there a chance for you to weight your storage , let say using load cells?

 

Good luck,

Breizh

Maybe I don't understand the system, but how is corrosion inhibitor availability calculated from the tank level? Doesn't the tank level give a volume? Isn't availability the amount of time an equipment is available to run. How does a tank volume in Liters equate to an Available Time? What am I understanding wrong here?
