Hello,
I have two floats of same type installed on a gas suction scrubber vessel. One of them actuates an electrical contact to generate LAHH SD digital output; while the other one actuates a pneumatic vent which in turn actuates a pneumatic dump valve.
The float is mounted on a nozzle which is a pipe extending 6-8 inches out of the scrubber vessel. The same pipe extends inside the scrubber vessel by 10-12 inches. So the float which is 4-5 inches in length operates within the nozzle pipe's outside length and not directly inside the vessel.
The problem is that For some reason, there is extensive foam formation inside the scrubber. This foam gets stuck in the nozzle pipe inside the vessel and eventually clogs up the float in one place thus inhibiting its operation.
My questions:
1. Is the design of the nozzle correct i.e. extending the nozzle inside the vessel? My guess is that this extension of pipe inside the vessel is causing it to become a dead end and a place for foam accumulation.
2. What would be good, cost effective level condensate sensing alternatives in this case which would also be impervious to foam formed inside?
Thanks
