OPTIMASS 6400
The OPTIMASS 6400 is a versatile, twin bent tube Coriolis mass flowmeter engineered for superior performance and high accuracy across virtually any industrial application. Its robust design and high-end options make it ideal for extreme conditions, ensuring reliable operation for:
- Custody Transfer (CT): Approved for highly accurate filling and transport measurements in the oil and gas industry.
- Cryogenic Media: Perfectly suited for applications like Liquefied Natural Gas (LNG) down to -200°C / -328°F.
- High-Temperature/Pressure: Handles operating temperatures up to 400°C / 752°F and pressures up to 200 barg / 2900 psig.
- Process Control: Provides precise mass flow, concentration, and density measurements in petroleum, chemical and food & beverage sectors.
- Safety Instrumented Systems (SIL 2/3): Suitable for critical safety applications.
Key Applications in Industries
The OPTIMASS 6400 is the reliable choice for accurate measurement and process control in the most demanding environments.
- General Industry (Process, Chemical, Food & Beverage):
- Concentration & Density Measurement: Real-time analysis for quality control.
- Batching, Blending, and Dosing: High-accuracy control for reactors and mixing.
- Challenging Fluids: Reliable measurement of liquids with transient gas entrainment, super critical gases, and extreme temperatures (-200…+400°C / -328…+752°F).
- Custody Transfer: Accurate bulk loading and pipeline transfer.
- Oil & Gas Industry:
- Metering Skids & Pipeline Transfer: High-accuracy flow and density for commercial transactions (CT approved).
- Liquefied Natural Gas (LNG): Crucial measurement for cryogenic LNG applications.
- Multiphase Measurement: Applicable for upstream oil and gas processes.
- Density Measurement: Dedicated in-line or bypass density monitoring.
- Bulk Loading: Accurate loading and unloading of tankers and vessels.
