Utility App for wireless control of atmospheric distillation analysers from ORBIS BV that are used in Petroleum & Petrochemical Laboratories. The app is capable of controlling the atmospheric distillation analysers of ORBIS BV, provides information about the analysers and reports the results of the analysers in a tabular and graphical manner. A set of standard methods allows to easily set up measurement programs that can be send to one of the connected analysers. A status screen provides information about the current status of each sample currently running on one of the analysers. Results can be viewed real time while the instrument is running or upon completion of the test. Results can be exported via ftp connection in xml format to a remote database (LIMS) Laboratory information management system. or printed on a Zebra thermal printer. The format of reporting to the printer or LIMS can be set easily on a formatting screen which can be set as a global default setting or for each standard method or program individually. The program parameters for each Sample (tasks) that are due to run ,currently running or being finished can be changed at all time. The parameters that can be changed are depending on the status of each task. Reference samples can be monitored using the reference screen showing consistency of each analyser. Frequency of verification and recalibration of the analysers can be set in the system settings screen along other parameters.
Oil density
This tool calculates the standard density of oil products based on measured apparent density. It automatically queries density tables and computes volume correction factors for accurate standard volume and mass calculations. Improve efficiency and accuracy compared to manual methods.
- Calculates standard oil density
- Queries petroleum density tables
- Computes volume correction factor (VCF)
- Calculates standard volume and mass
- Adheres to GB/T 1885-1998 national standard

The professional petroleum metering calculation tool of GB/T 1885-1998 national standard is adopted to automatically query the standard density table of the petroleum metering meter, convert the apparent density measured by the petroleum densitometer into the standard density, and calculate the volume correction factor (VCF) at the same time, so as to calculate the standard volume and mass of oil products, which improves the efficiency and calculation accuracy compared with manual query.
