Flow measuring technology for liquids, gases and steam

Flow is one of the most frequently measured process variables in industry. Water, natural gas, steam, mineral oil, chemicals or wastewater are only some examples of fluids that have to be measured day in, day out. There is no single, across-the-board technology suitable for all these applications, so Endress+Hauser will be happy to advise you on the flowmeter best suited to your process needs.
