SIRA device for measuring odorant concentration

SIRA ODOR Messgerät Odormittelkonzentrationen Oberteil

GAS GRID SAFETY

Natural gases and hydrogen are by nature low in odor or even odorless to humans.

In order for potential leaks to be noticed and eliminated in a timely manner thanks to someone smelling the typical gas odor, these gases are supplemented with an odorant (i.e. odorized) in the gas grid.

A new process gas analyzer uses UV spectrometry for the legally required odorization check.

ANALYSIS SYSTEM FOR MEASURING ODORANT CONCENTRATION

Adapted analyzer systems are available for the relevant odorants. The central assembly of the analyzer system is the UV sensor in conjunction with a zero gas generation system matched to the odorant.

Adaptation of the analyzer system in the event of a change of odorant is possible at any time.

OdorantMeasuring rangeError limits
Tetrahydrothiophene (THT) 0 – 50 mg/m³  0.75 mg/m³ or 10 % of the measured value
Gasodor® S-Free 0 – 50 mg/m³ 0.75 mg/m³ or 10 % of the measured value



EASY AND STRAIGHTFORWARD TO OPERATE

Configurable parameters

  • adjustment of different parameters according to users’ needs, e.g. measurement cycles, units, storage intervals, views, reports

Control concept dependent on access rights

  • access rights via user level
  • configurability and transmission of measurement data and reports

 

Cycled measurement from 120 seconds to 24 hours

  • setting of measuring cycles
  • saving of measurement results
  • history with graphic display
  • protecting the setting of measuring cycles

Automatic reporting

  • generating reports from the saved measurements (duration of reporting periods can be adjusted freely)

Export function of measurement data

  • saving measurements and reports on the device, including exporting

Uploading data in the cloud

  • accessing measurements and reports on a file server via the internet

Remote monitoring (remote maintenance possible)

  • retrieval of measurements and the resulting graphs
  • setting of measurement cycles and export of measurement data and reports

GSM connectivity

  • dispatch of alarm emails or SMS messages to preset destinations when threshold values exceed or fall below the set limits (the email or SMS indicates the device and the reason for the alarm)

Communication options

  • Modbus TCP
  • Profibus
  • Profinet
  • other on request
