The iSonic is an inteligent and versatile ultrasonic Meter / Controller designed to measure Level, Volume and Open Channel Flow. iSonic's unique features allow accurate measurements in harsh environments. The iSonic uses the measured signals for control purposes and /or recording to an internal data-logger.
  • In fresh and waste water applications, iSonic 1000 measures level and calculates flow rates through weirs or flumes using one of it's pre-programmed conversion formulasor a 15 point conversation table. The two transducer inputs can be added, subtracted and averaged. Totalizer functionality is provided for each channel.
  • In silos and tanks, the iSonic 1000 measures level and calculates the volume of the solids or liquids they contain by using one of its standard tank shape pre-programmed conversion formulas. Volume can also be calculated using a custom 15 point conversion table.
  • In tanks containing chemical substances with high vapour pressure, iSonic 1000 maintains its accuracy by constantly measuring the speed of sound in the environment, in conjunction with a specialized sensor. iSonic 1000 maintains its accuracy in any application where the atmospheric environment is not standard.
  • The iSonic 1000 can be powered by either AC (90-230V) or DC (12-14V) power. A low power sleep/operate mode is provided for installations where no mains power is available. In low power mode, the iSonic 1000 typically draws only 30mW/H.
  • ultrasonic meter controller data communication logging data engineering technology south africaiSonic 1000 can interface two Ultrasonic Transducers simultaneously, performing independent or combined Level,Volume and Open Channel Flow measurements. Additionally, the instrument can be interfaced to two Temperature sensors, two Analogue inputs (0-5V or 4-20mA) and four Digital inputs.
  • The instrument is able to provide limited 24V power to external loop sensors or 12V power for an external MODEM.
  • As a controller, the instrument can be programmed with various set points resulting in analogue outputs (PID) and relay (five) actions according to the measured inputs. Complex switching sequences are possible and pump rotation for even wear has been implemented.
  • As a recorder, the instrument is capable of storing as much as one-month's data at one-minute intervals or more than a year's data at 15-minute intervals, whilst logging all data channels.
  • Configuration of the instrument can be done via the six function keys and the graphical LCD display or via a personal computer (PC) using the custom software supplied with the unit. The configuration is password protected.
  • Using a personal computer and the custom software supplied with the unit, recorded data can be displayed in graphical format. Minimum, maximum and average flow for a specified time interval can be calculated and displayed in tabular and graphical format. The recorded data can be exported in .CSV format.
  • Remote communication with the instrument is possible using RS232/RS485, MODEM or GSM MODEM (Data & SMS). Via this interface, configuration changes and data retrieval are possible. Using the RS485 interface, a network of up to 32 iSonic 1000's can be created. The units can be configured to send SMS to a technician when certain selected alarms have occurred. Also, using SMS, current information such as totalizer value, current level/flow reading, temperature reading etc, can be interrogated.
