1.3 Features Highly accurate flow measurement Accuracy better than 1% thanks to two parallel path design. Velocity of Sound (VOS) monitoring Diagnostics for verification The OPTISONIC 8300 provides a number of online diagnostic parameters and functions. For example since the process medium is known, the velocity of sound can be calculated with the input of temperature and pressure. The calculated velocity of sound can be monitored against the measured value. In this way not only the flow sensor is continuously diagnosed but also the temperature and the pressure sensor. In addition, the...

Mass flow and energy flow calculation The OPTISONIC 8300 integrates the functionality of a flow computer in a flowmeter. Two optional current inputs for pressure and temperature allow the OPTISONIC 8300 to provide output like corrected volume flow, mass flow and energy flow. In case more flexibility or I/O options are required, the flowmeter can also be combined with the Summit flow computer. ATEX / IECEx ATEX / IEC-Ex certification incl. zone 0. In the case, gas flow must be measured in vent lines where a combination of flammable gases and oxygen may occur, the OPTISONIC 8300 can be used...

1.4 Measuring principle • Like canoes crossing a river, acoustic signals are transmitted and received along a diagonal measuring path. • A sound wave going downstream with the flow travels faster than a sound wave going upstream against the flow. • The difference in-transit time is directly proportional to the mean flow velocity of the medium. Figure 1-1: Measuring principle 1 Sound wave against the flow direction 2 Sound wave with the flow direction 3 Flow direction
