Introduction
This chapter contains an outline of how the 3098 specific gravity meter works, defines some of the
terms commonly used in the manual, and also gives some practical applications for the 3098.
1.1 Safety guidelines
Handle the 3098 specific gravity meter with great care.
• Do not drop the meter.
• Do not use gases incompatible with materials of construction.
• Do not operate the meter above its rated pressure.
• Do not expose the meter to excessive vibration (> 0.5 g continuous).
• Ensure all electrical safety requirements are applied.
• Ensure good ventilation around the meter / cabinet to prevent gas build up in the unlikely event
of a leak.
• Ensure meter is not transported when it contains hazardous substances. This includes fluids
that may have leaked into, and are still contained, within the case.
• Ensure that a Balston coalescing filter is fitted into the gas supply line to the 3098 meter.
Either a type 85 or a 91S6 (as supplied) MUST be fitted to comply with ATEX/IECEx
approval requirements.
• To return a meter, refer to Appendix C for more information on the Micro Motion return
policy.
Safety messages are provided throughout this manual to protect personnel and equipment. Read each
safety message carefully before proceeding to the next step.
The 3098 specific gravity meter is normally installed in an IP rated enclosure prior to leaving the factory. In
some instances however, the 3098 specific gravity meter may be supplied without an enclosure, in which
case the environmental and thermal performance of the meter cannot be guaranteed. Warnings are given
throughout this manual when the performance of the meter may be affected by this.
For technical details, please refer to the system installer.
The pressure relief valve has been factory set for the unit to conform to the Pressure Equipment Directive.
Under no circumstances should this setting be changed.
For further information, contact the factory using the details on the back page of this manual.
