Can the capillary be removed?
Thread Content
Honeywell’s capillary double-flange level gauge has the lower flange below the floor slab and the upper flange above it. The floor slab can only be passed through via the capillary; if you don’t want to cut the floor slab, it’s possible to avoid removing the capillary from the flange.
Capillary diaphragm differential pressure transmitters have a conductive medium, usually silicone oil, filled inside the diaphragm capsule and capillaries, and they cannot be removed. After removal, it is necessary to return to the manufacturer to refill the silicone oil and recalibrate it. In this case, it is generally necessary to make an opening in the floor slab.
Cut the floor slab; don’t bother with the capillaries
Is it connected by threads? Some brands are welded together!
Forget about pulling out the capillary tube – the openings for equipment on this floor aren’t usually right next to the equipment itself. Can’t you just push the flange against the opening next to the equipment? If that doesn’t work, then consider drilling a new hole on that floor
Hehe, don’t overthink it; you can’t do this by yourself. . . . We encountered such a problem in a previous project: the differential pressure level could not be measured accurately. Upon inspection on the second floor, it was found that the capillary tube went straight through the steel floor slab, as the slab had not been cut. . . It was only later that I learned there was a smart person on the construction team. . . The differential pressure level gauge has been sent back to the factory
No, cut the floorboard; making a hole costs hardly any money. Bro, how much does a Honeywell one cost? We just bought an ABB one.
The capillary cannot be pulled out; cut the steel plate instead
Bought 36 of them, capillary double flanges; the price including taxes is around 5800
