Plants that need Coriolis mass flow measurement on standard gas and liquid lines often have to choose between entry-level meters with limited capability and premium instruments priced beyond what the application requires. The OPTIMASS 5400 is a twin semi-bent tube Coriolis mass flowmeter for standard process applications with gases and liquids, positioned between entry-level and premium Coriolis meters. It directly measures mass flow, density, and temperature, and also provides volume flow, concentration, and flow velocity data.

The meter handles process temperatures up to 356°F (180°C) and pressures up to 1,450 psig (100 barg). The sensor housing provides a typical burst pressure resistance up to 2,900 psig (200 barg), adding a second line of containment. Optional mass flow accuracy is ±0.1% for flow rates above 10% of nominal flow, and the meter offers a wider turndown ratio than comparable Coriolis meters in its class.

Entrained gas management technology keeps measurement stable across a wide range of gas fractions and complex flow conditions. It also provides two-phase flow indication and monitors gas volume fraction (GVF) in liquids.

The lightweight case uses fewer materials and components than previous generations of Coriolis flowmeters, reducing weight and installation height for transport and commissioning. Its compact footprint suits mobile and skid-mounted systems, trucks, rail tankers, and portable rigs in non-custody transfer applications. The meter is available in compact and remote versions and serves as a flange-to-flange replacement for existing OPTIMASS 1000 series installations. Flange connections range from 0.5 to 4 in (DN10 to DN100), with various hygienic connections also available.

For hygienic applications, the meter is EHEDG and 3-A certified and suited to media with low to moderate viscosities. When installed vertically, it is self-draining and withstands clean-in-place (CIP) processes using acids and hot water, as well as sterilization-in-place (SIP) processes with saturated steam. Marine approvals support consumption measurement of marine fuels, including marine diesel oil (MDO) and marine gas oil (MGO), on ships.

The MFC 400 signal converter uses modular electronics with three configurable 4 to 20 mA outputs and supports HART 7, Modbus, FOUNDATION Fieldbus, PROFIBUS-PA/DP, PROFINET, PROFINET over Ethernet-APL, and EtherNet/IP. Integrated Bluetooth provides wireless access.

Built-in OPTICHECK diagnostics continuously monitor instrument health and application conditions to support condition-based maintenance and process optimization. On-site verification runs without process interruption. Paired with the OPTICHECK Flow Mobile app over Bluetooth, operators can commission, monitor, and verify the meter from a distance and generate a verification report at the push of a button, which helps in hard-to-access installations. OPTICHECK DTM provides remote access from the control room.
