A Clear Concept Innovation
- The innovative 18-path configuration
The FH8500 multi-path ultrasonic flowmeter is the only flowmeter that integrates 36 transducers generating 18 ultrasonic beams, providing acomplete 3D view of the flow velocity profile
- A Fully Integrated Electronics
Thanks to a powerful integrated processing unit (using leading-edge digital technology), the FH8500 offers an integrated and compact metering solution
FHview Communication Software
- I/O setting
This screen gives access to the configuration of the analogue 4-20 mA inputs and outputs.Users can allocate one parameter, for example flowrate or VOS (Velocity of Sound), to each of them and adjust the operating range.
- Global parameters display
This screen provides instantaneous information on the FH8500 flow conditions such as gross flowrate, average VOS, etc. In addition, users get data relating to the operating status of meter, number of working beams, alarms,and average ultrasonic signal level.
- Measurement integrity
This screen gives all necessary parameters relating to the 18 ultrasonic paths, VOF (Velocity of Flow), VOS and signal gain. These data allow the user to check the measurement integrity on each single beam
- Graph visualisation
A range of functionalities is available to track and view average VOF, VOS and signal gain over time
- Data and events loggers
Users can download and record data from the flowmeter with respect to the previously defined period of time. These data relate to the flowmeter parameters. Dated events such as alarms can be downloaded and recorded
