Description
The KROHNE OPTIMASS 1000/1400 is a twin straight-tube Coriolis mass flowmeter for liquids and gases in sizes DN 15 to 50. It measures mass flow, density and temperature with ±0.15% of rate for liquids and ±0.5% for gases, and its straight tubes drain fully and are easy to clean.
The duplex stainless steel tubes are rated to 100 barg and −40 to +130 °C, with flanged or hygienic connections. The compact MFC 400 converter adds diagnostics and entrained gas management, and the meter carries ATEX, cFMus and NACE MR0175 approvals.
Argonmark Ltd supplies KROHNE instruments across Bangladesh — Dhaka, Chattogram, Gazipur, Narayanganj and the gas fields, refineries, terminals and power plants beyond. Send us the model, range, process connection, output and any hazardous-area requirement, and we will confirm the right configuration, lead time and price.
