•SENIORSONIC™ FLOW CHARACTERIZATION CALCULATIONS. The SeniorSonic™ Mark III meter

calculates/estimates flow-characterization information such as symmetry, cross-flow, turbulence, profile factor and swirl angle.

•IMPROVED VELOCITY ESTIMATION. The Mark III utilizes an improved algorithm for using chord proportion history to estimate the flow velocity in the event of a chord failure. (Applicable on SeniorSonic™ models 3400 and 3422 and JuniorSonic™ model 3420.)

•12-POINTPIECEWISE-LINEARIZATION. The Mark III offers up to 12 points for piece-wise linearization whereas the Mark II offers 10 points.

•TWO INDEPENDENT FREQUENCY OUTPUT PAIRS. The Mark III offers two independent frequency output pairs, a feature particularly useful in custody transfer applications. Each frequency pair is individually configurable and utilizes a separate ground so that each pair can be wired to a separate flow computer.

•NEW FREQUENCY CONTENT OPTIONS. The Mark III meter adds four new frequency content options (gas velocity, sound velocity, energy rate, and mass rate) to the standard options (actual or standard flow rate).

•FREQUENCY BI-DIRECTIONAL OPTION. This new option allows a frequency pair to be configured so that the selected content is represented by the "A" channel when flowing in the forward direction and by the "B" channel when flowing in the reverse direction.

•CONFIGURABLE "B" CHANNEL PHASE. Each frequency pair "B" channel phase is individually configurable so that its phase (relative to the "A" channel) can be used to determine the flow direction.

•BATCH DATA SMOOTHING. The Mark III meter offers a method for "smoothing" batch data that is particularly useful for applications that rely on the frequency output signals.

•TWO INDIVIDUALLY CONFIGURABLE DIGITAL OUTPUTS PER FREQUENCY PAIR. Each frequency output pair has two associated, individually configurable digital outputs. Each digital output is individually configurable for content and logic polarity. A test mode is available for testing each digital output pair.

•ETHERNET CONNECTIVITY. The Mark III meter adds an optional Ethernet port in addition to two RS-232/RS-485 serial ports. This allows for multi-user, network-based access over an intranet.

•HIGH-SPEED SERIAL COMMUNICATION PORTS. The Mark III supports independently selectable baud rates on each of its serial communication ports up through 115200 bits/sec.

•FULL-DUPLEX SERIAL COMMUNICATION. The two standard RS-232/RS-485 serial ports can be configured for either half-duplex or full-duplex operation. Full-duplex communication allows a highly reliable TCP/IP protocol to be used by Daniel MeterLink which provides full functionality as is available via the optional Ethernet connection, including log access and waveform viewing.

•AUTOMATIC COMMUNICATION-PROTOCOL DETECTION. The Mark III meter automatically detects all supported communication protocols which simplifies communication set-up.

•OPERATING SYSTEM. The Mark III utilizes an enterprise-class, protected-mode Linux operating system for enhanced reliability and future upgradability.
