Electric measuring device having a small-bore liquid container with improved electrode sealing means

摘要

An electromagnetic flowmeter having a small-bore flow tube having a thick-walled plastic tube having a conically-relieved electrode-receiving bore. A compression ring around the conical part of the tube squeezes the plastic sealingly between the electrode and the ring. In assembly, compressive force exerted by Belleville springs or washers causes the plastic to flow into sealing contact with the electrode.
