Problems with liquid level measurement in crude oil storage tanks
Thread Content
The radar level gauge for the crude oil tank is installed on the wave guide of the tank. When the weather gets colder, crude oil deposits form on the wave guide, resulting in interference signals; it is necessary to flush it with boiling water each time before it can function properly. Does anyone have any good solutions?
Try using hot water for heating when the temperature is low
It’s tricky with the built-in one; replace it with a servo
This facility’s crude oil tanks are equipped with K-TEK external float level transmitters and electric heat tracing; they have been exposed to wind and rain for over a decade without any problems. For reference.
Specific operating conditions, detailed analysis, external-mounted level gauge
Radar level gauges have a filtering function that can remove the noise reflected from the inner wall; give it a try to see the effect.
If scaling is severe, it seems that the filtering setting can’t remove it
Let me put it this way: using a horn-type radar level gauge on a floating roof tank is basically a bad idea. 1. Modification: Switch to a guided wave cable type level gauge, but the necessary installation conditions may not be available. 2. Direct demolition: The light guide tape-type level gauge requires virtually no maintenance, as it is connected to a floating boat......
I haven’t encountered this situation before; the echo signal weakens. Try lowering the filtering level
All of our crude oil tanks are equipped with radar systems, and we’ve never encountered such a situation. With insulation added to the tanks, there should be no problems. Try using radar signal filtering on the upper-level computer to remove the noise.
Radar can be affected by crystalline vapor and the like; switching to radio frequency admittance might be an option. Depending on the operating conditions, magnetostrictive effects can also be considered
