Two and three path diametrical sensor configurations are recommended for applications that do not have normal upstream straight runs to produce well developed velocity profiles.
The average axial velocity component for each acoustic path is utilized to establish the velocity profile.The velocity profile is then numerically integrated over the conduit’s cross-sectional area to determine the volumetric flow rate. As a result, flowmeter accuracy is relatively independent of the velocity profile.
The Vantage 4800 has a built-in datalogger with eight distinct channels for logging flow and totals.The storage capacity for a single channel at 5 minute intervals is 113 days. Logger data may be visually accessed on the display of the meter in pre-programmed time intervals or retrieved through a laptop or optional modem installed within the enclosure of the meter.
Daily Averages: Daily summary allows viewing of the previous eight days.This includes times, dates, averages, minimums, maximums and totals.
Logger Graph: In addition, a bar graph may be visually displayed on the Vantage.The graph will display the stored logger data in pre-programmed time intervals.
Data Retrieval: Logger data can be collected by using a laptop computer or an optional modem installed within the Vantage enclosure.
