Is it feasible to install an electromagnetic flowmeter on a pipeline with anodic protection?
Thread Content
In the dry absorption process of sulfuric acid production, there is a section of the sulfuric acid pipeline that is protected with anode protection; flow measurement is required in this area. Is it feasible to use electromagnetic flowmeters for this purpose? ?
Okay. We use them in the same way as well – the electromagnetic flowmeters from Shanghai Guanghua Ailimet; they’ve been in use for over 4 years now, and they work quite well.
What should be noted during installation?
It should be possible to equalize the potential of the housing, fluid, pipes, etc. I haven’t used it in any specific applications yet; does anyone with expertise have any opinions on this?
It is possible; both grounding rings must be properly grounded. The pipe flanges on both sides should be connected using thick copper wire of 16mm2 or larger, with the wiring passing around the sensor. It is advisable to include DC noise suppression in the electromagnetic flowmeter converter.
