Description
The KROHNE OPTIMASS 7000/7400 is a single straight-tube Coriolis mass flowmeter that drains completely, is easy to clean and has a low pressure drop. It covers sizes 06 to 80 with maximum flows up to 560,000 kg/h, at ±0.1% of rate for liquids and ±0.35% for gases, and measures density from 400 to 2,500 kg/m³.
The measuring tube is available in titanium (to 100 barg, −40 to +150 °C), stainless steel, Hastelloy or tantalum, with flanged or hygienic connections and 3-A, EHEDG, FM/CSA and MID approvals.
