OPTIMASS 2000

1.1 The solution for bulk mass flow measurement

Whilst the OPTIMASS 2000 has been developed to meet the demanding custody transfer requirements of the oil and gas industry, it is well suited to bulk measurement in many applications. The option of Super Duplex (UNS S32750) provides a maximum operating pressure of 180 barg.

A high level of performance makes the OPTIMASS 2000 suitable for the bulk measurement of petroleum and oil as well as products like syrup, molasses and raw chemicals.

Combined with the power of the MFC 300, the OPTIMASS 2000 will provide accurate measurement of volume, mass; density and concentration.

1.4 Measuring principle (twin tube)

Static meter not energised and with no flow

1 Measuring tubes 2 Drive coil 3 Sensor 1 4 Sensor 2

A Coriolis twin tube mass flowmeter consists of two measuring tubes 1 a drive coil 2 and two sensors (3 and 4) that are positioned either side of the drive coil.

Energised meter

1 Measuring tubes 2 Direction of oscilation 3 Sine wave

When the meter is energised, the drive coil vibrates the measuring tubes causing them to oscillate and produce a sine wave 3. The sine wave is monitored by the two sensors.

OPTIMASS 2000

Energised meter with process flow

1 Process flow 2 Sine wave 3 Phase shift

When a fluid or gas passes through the tubes, the coriolis effect causes a phase shift in the sine wave that is detected by the two sensors. This phase shift is directly proportional to the mass flow.

Density measurement is made by evaluation of the frequency of vibration and temperature measurement is made using a Pt500 sensor.
