Technical Datasheet Sensor for mass flow • The optimum meter for demanding applications • A single straight measuring tube • Choice of 4 tube materials The documentation is only complete when used in combination with the relevant documentation for the signal converter.

1.1 Overview The OPTIMASS 7400 is the only sensor for mass flow with a single straight measuring tube that is available in Titanium, Stainless Steel, Hastelloy® or Tantalum. Compact version 1 Modular electronics with a range of output options (see separate documentation for details). 2 The power of the MFC 400 gives comprehensive diagnostics together with Entrained Gas Management (EGM). 3 Available with a range of flange and hygienic connections. Remote version

Highlights • Outer cylinder typical burst pressure greater than 100 barg / 1450 psig, with optional PED approved secondary pressure containment available • Easily drained and easy to clean • Resistant to installation and process effects • Excellent zero stability • Low energy consumption, means lower operating costs • Rapid signal processing, even with product / temperature changes • Modular electronics with data redundancy - "plug & play" replacement of electronics Water & wastewater Mining & building materials Iron, steel and metal processing Food & beverage Oil, gas and alternative fuels...

1.2 Features and options Features • Available as compact or remote. • Low pressure loss - single straight tube design guarantees a low pressure drop across the meter. • Self Draining. • Easy to clean. • With advanced Entrained Gas Management (EGMTM) the meter maintains operation over a wide range of gas fractions and complex flow conditions. Connection options • A range of flanges up to ASME 600 / PN100. • Supports a wide range of industry standard hygienic connections. • Adaptable to suit customer's hygienic connections. Heating jacket and purge port • Heating jacket option for use with...

2.1 Measuring principle (single tube) Static meter not energised and with no flow Measuring tube Drive coil Sensor 1 Sensor 2 A Coriolis single tube mass flowmeter consists of a single measuring tube 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 tube causing it to oscillate and produce a sine wave ③ . The sine wave is monitored by the two sensors.

Energised meter with process flow 1 Process flow 2 Sine wave 3 Phase shift When a fluid or gas passes through the tube, 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.
