IntelliScent™ Odorant Monitor

When a Sniffer Isn’t Enough

Why wait for a monthly sniff test? Ensure your distribution system is properly odorized at all times: install Welker’s IntelliScent™ Odorant Monitor to frequently and objectively measure odorant levels.

Automated Measurement Cycles

Unlike human sniffers, the IntelliScent™ isn’t restricted by schedules or olfactory fatigue. Microcontrollers regularly sample the natural gas stream, allowing for frequent monitoring of injection odorizers and incoming odorant levels. Electrochemical sensors objectively measure odorant levels in calibrated units of lb/MMscf or mg/m3. Repeat measurement cycles at 1-, 2-, 4-, 6-, 8-, 12-, or 24-hour intervals.

High Caliber Measurement

Automatic System Calibration

Program the IntelliScent™ for automatic system calibration at daily, weekly, or monthly intervals. System calibration runs a complete measurement cycle using a cylinder of calibration gas and compares the results to the preset values; any deviation is corrected to ensure the accuracy of subsequent measurement cycles.

IntelliScent App
Communication is Key

Wireless Capabilities

Designed for Class I, Division 1 hazardous areas and capable of analog or MODBUS output, the IntelliScent™ is well-suited for remote locations. Error conditions are reported as multi-level fault values, making remote diagnosis possible regardless of output type. When you have to be on site, improve the field experience with the free IntelliScent™ Odorant Monitor iOS app from the Apple App Store. Use the app on your mobile device to wirelessly interrogate and command the unit from up to 25 feet away, view current and historical data, and access tools and troubleshooting resources like the user manual.
