Introduction

The ODORATOR 2 is a handheld, portable, electronic GNSS based audit system used to evaluate and record the odor levels within a utility’s gas stream with respect to actual test locations. Natural gas (methane) and propane are two common gases typically odorized and distributed for consumption.

Sample gas to be tested enters the ODORATOR 2 through the quick connect fitting at the gas supply inlet port. Internally, the sample gas passes through an internal five micron filter to the input of a low pressure regulator. It then passes from the output of the low pressure regulator to the flow metering valve. This valve, located on the top panel of the ODORATOR 2, is controlled by the user. After passing through the valve (when partially opened), the gas enters a mass flow sensor. This is the heart of the ODORATOR 2. The mass flow sensor responds to gas flow within the range of the flow metering valve. The signal from the mass flow sensor is then converted to a digital signal, processed and fed to a liquid crystal display (LCD) for the user’s use. Metered gas from the mass flow sensor then passes to the mixing chamber where it is combined with fresh air drawn in by a blower. The user then sniffs the gas / air mixture at the exhaust port as part of the test. If no odor is detected in the exhaust mix the flow metering valve is incrementally opened and the exhaust port sniffed until odor is readily detectable at which time the user presses the READ switch to automatically record the corrected percent gas in air by volume, GNSS location (GPS and/or GLONASS), test time, test date and various instrument parameters. While driving to the various test points in the distribution system the ODORATOR 2 also automatically records the GNSS location, date, time and various instrument parameters to be able to show the actual breadcrumb trail used. The electronics and the speed of the blower are calibrated so that the concentration of the gas / air sample at the exhaust port agrees with the LCD reading at 20% of the Lower Explosive Level (LEL). For methane or natural gas the LEL is typically 5.0% and for propane the LEL is typically 2.2%. All readings are automatically corrected for atmospheric pressure and temperature via an embedded microcontroller and associated sensors. Depending on how far the flow metering valve is opened, the concentration of gas in air at the exhaust port will be anywhere from zero up to approximately 2% for methane. An alarm and the display warn the user of instrument problems or high reading values.

INTRODUCTION

The ODORATOR 2 continuously monitors its health and operational status. Typical operational checks include but are not limited to: blower speed, battery state-of-charge, GNSS, memory card, communications buss, power supplies and calibration interval.

Included but not required for odor level testing is OdorSeer PC software for managing the recorded data, mapping, report generation and instrument configuration. Connectivity interfaces include USB 2.0 and Bluetooth. Refer to the OdorSeer manual for details.

A replaceable, rechargeable Li Ion battery pack is used to power the ODORATOR 2. An external power supply is used to re-charge the battery pack. The ODORATOR 2 is designed and intended to be used in accordance with the GPTC Guide For Gas Transmission And Distribution Piping Systems, (49 CFR) 192.625 Subpart L, dated 10-1-13, the American Society For Testing And Materials Standard D 6273 – 08 and NFPA 58. Supply gas must be natural gas (methane) or propane and of high quality. Blended or mixed gases as sometimes found during peak shaving cannot be tested using the ODORATOR 2.

Warnings and Cautions

Prior to use, the user should read all warnings and cautions, instructions for operation and maintenance requ ire men ts contained in this user’s m anu al.

WARNING: DO NOT USE THE ODORATOR 2 OR BREATHE IN GAS FROM SOURCES WHICH MAY CONTAIN TOXIC LEVELS OF CHEMICALS SUCH AS HYDROGEN SULFIDE (H2S) AS IT COULD BE HARMFUL TO HUMAN HEALTH AND SAFETY TO DO SO. SOURCES WHICH MAY CONTAIN TOXIC LEVELS OF CHEMICALS INCLUDE BUT ARE NOT LIMITED TO PRODUCTION SYSTEMS AND LANDFILLS.

It is the sole responsibility of the product purchaser/ owner to ensure that: (1) all users of the ODORATOR 2 read, understand, and comply with the precautions, instructions for operation and maintenance requirements contained in this manual; (2) the ODORATOR 2 is only used in a proper and safe manner; and (3) while using the ODORATOR 2, users are not inhaling or sniffing dangerous materials that could cause injury or death.

WARNING: DURING OPERATION, KEEP THE ODORATOR 2 AWAY FROM OPEN FLAMES. INLET SUPPLY PRESSURE SHOULD NOT EXCEED FOUR PSIG. INLET PRESSURES IN EXCESS OF FOUR PSIG COULD RUPTURE THE LOW PRESSURE REGULATOR DIAPHRAM, VENT THE GAS OUT OF THE INSTRUMENT AND CAUSE AN INSTRUMENT FAILURE. THE RECOMMENDED INLET SUPPLY PRESSURE IS 7” WATER COLUMN.

WHEN OPERATING THE ODORATOR 2 YOU WILL BE WORKING WITH FLAMMABLE METHANE OR PROPANE GAS WHICH IS POTENTIALLY DANGEROUS IF NOT HANDLED PROPERLY. METHANE GAS FROM A LECTURE BOTTLE MAY BE ODORLESS, COLORLESS AND IS EXPL OSI VE IN CONCENTRATIONS OF APPROXIMATELY 5.0 TO 15.0 PERCENT BY VOLUME IN AIR. PROPANE’S EXPLOSIVE RANGE IS APPROXIMATELY 2.2 TO 9.6 PERCENT BY VOLUME IN AIR.

WHEN NOT OPERATING THE ODORATOR 2 CLOSE ALL VALVES AND TURN THE ODORATOR 2 OFF.

ANY TIME GAS IS BEING PASSED THROUGH THE ODORATOR 2 THE POWER MUST BE TURNED ON. THIS WILL DILUTE THE GAS AT THE EXHAUST PORT AND PREVENT POCKETS OF CONCENTRATED GAS FROM ACCUMULATING.

100% LEL IS APPROXIMATELY EQUAL TO 5.0% METHANE OR 2..2 % PROPANE GAS BY VOLUME IN AIR. AS LONG AS A REFERENCE CGI READS SAFELY BELOW THE LEL (20% LEL OR LESS) YOU SHOULD NOT HAVE ANY PROBLEMS WITH A FLAMMABLE MIXTURE BUILDING UP.

ANY SUSPICION OF A GAS LEAK BY UNEXPLAINED SOUND OR OPERATION OF THE ODORATOR 2 IS REASON TO IMMEDIATELY SHUT OFF THE GAS SUPPLY VALVES AND THEN SEEK THE CAUSE.

IF INDOORS, DO NOT TURN THE ODORATOR 2 ON UNTIL A REFERENCE CGI INDICATES THE ENVIRONMENT IS SAFE. LIKEWISE, ALLOW THE ODORATOR 2 TO PURGE FOR AT LEAST ONE MINUTE AFTER A REFERENCE CGI ALSO INDICATES THE ENVIRONMENT IS SAFE. THE

ODORATOR 2 IS PENDING CERTIFICATION TO BE SAFE FOR USE IN CLASS 1, DIVISION 2, GROUP D HAZARDOUS AREAS.

PERFORM ANY AND ALL MAINTENANCE IN A LOCATION KNOWN TO BE NON-HAZARDOUS. TO REDUCE THE RISK OF IGNITION OF A FLAMMABLE OR EXPLOSIVE ATMOSPHERE, THE

BATTERY PACK MUST BE CHANGED OR CHARGED ONLY IN A LOCATION KNOWN TO BE NONHAZARDOUS.

NO ATTEMPT SHOULD BE MADE TO REPAIR THE INSTRUMENT BY THE USER. SHOULD THE INSTRUMENT NOT WORK PROPERLY OR INDICATE AN ERROR OR WARNING, REFER TO THE TROUBLESHOOTING SECTION OF THIS MANUAL.

SUBSTITUTION OF COMPONENTS MAY IMPAIR SAFETY. NO USER SERVICEABLE COMPONENTS ARE CONTAINED WITHIN THE INSTRUMENT.

ONLY USE BATTERY PACK HPN 101311-0. TO REDUCE THE RISK OF IGNITION OF A FLAMMABLE OR EXPLOSIVE ATMOSPHERE, A USB

CABLE MUST ONLY BE CONNECTED IN A LOCATION KNOWN TO BE NON-HAZARDOUS. DO NOT OBSTRUCT OR BLOCK THE INTAKE OR EXHAUST PORTS.

CAUTION:

Do not store the gas sample hose in the case. The gas sample hose must “breathe” in fresh air to lengthen its useful life and not contaminate the instrument. A mesh bag attached to the carrying handle is included and recommended to be used for storage for storage.

CAUTION:

Because of inherent limitations, liquid crystal displays should not be subjected to extremes of temperature or humidity. If the instrument is exposed to a temperature below freezing

or above +49 oC (+120 oF), the liquid crystal display may temporarily cease to function properly and in some cases permanent damage may result. It is therefore recommended that the instrument not be subjected to extreme conditions such as a closed vehicle in direct sunlight or continuous sub-freezing temperatures.
