SIRA device for measuring odorant concentration
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.
| Odorant | Measuring range | Error 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
As part of our SIRA measuring device series, we at UNION Instruments are pleased to introduce the first new, innovative UV process gas analyzer for odorization monitoring to the market.
