Available from Hawk Measurement Systems , the Sultan flow measurement system operates by transmitting an Acoustic Wave signal from its transducer towards the liquid being monitored. The signal or echo is received by the transducer and then processed.
The time between transmission of the acoustic signal and reception of the echo is measured, and using the speed of sound through air, the distance from the transducer to the liquid level is then calculated. Flow through the channel or structure is then calculated from the level measurement and the user entered properties of the channel.
The Sultan flow measurement system uses sophisticated software to locate and track the correct echo without being affected by echos from fixed objects or changes in the liquid surface.
When the liquid level or surface conditions change, the system follows preselected signal tracking parameters. In the event of a total loss of signal, the system adopts signal recovery routines to relocate the correct liquid level.
Sultan flow and open channel measurement systems employ automatic gain control to compensate for changes in echo amplitude due to variations in environmental conditions.
Continuous current, voltage and relay outputs are provided. These outputs can be programmed for failsafe conditions in the event of a loss of signal or system malfunction.
These flow measurement systems can be used in the following applications:
- Environmental monitoring
- Industrial waste
- Open Channel Flow
- Power waste
- Sewage treatment
- Special flow requirements for unusual flow channels
- Water treatment
