Roots Rotary Meter Oil

Roots Meter Oil Picture

Environmentally Friendly ROOTS™ Meter Oil

 In direct response to expressed concerns for personal safety and environmental issues,DMD-Roots is introducing a new meter oil that is NOT rated hazardous by OSHA or the EPA and contains no substances subject to reporting or planning requirements under SARA TITLE III.

Most hydrocarbon-based oils used in the natural gas industry have limited occupational exposure limits.  Often these oils contain a dye that is added for improved viewing capability.  A commonly used component of the dye, Ethyl Benzene, produces a higher than desired toxicity level.  Our new and environmentally friendly ROOTS™ meter oil is still red in color but contains no toxic or hazardous ingredients.  The Material Safety Data Sheet (MSDS) for our new ROOTS™ meter oil permits handling with standard neoprene type gloves in lieu of Nitrite gloves recommended with most lubricants.  The Material Safety Data Sheet (MSDS) is available in hard copy or can be downloaded electronically via the link towards the end of this document.

Our new ROOTS™ meter oil is specially formulated and blended from a non-hazardous, state of the art R&O AW hydraulic oil additive package that inhibits oxidation and foaming.  The oil can also be used in any Series A1 (LM-MA) or Series B2 (TQM) meter and can be safely blended with previously approved ROOTS™ meter oils such as ROOTS® Versi-Temp 2 Meter Oil (Shell Tellus T15) and Grade 50 (Shell Diala AX).  The resulting oil color will vary depending on the quantities of each oil used in the mixture. Draining the old oil before adding the new oil is optional if oil color clarity is of concern.

Using this opportunity to address another customer concern, several new container sizes are being introduced.  While a sufficient quantity of oil will still be provided free of charge with each shipment for the initial filling of the meter, the net result is a reduced quantity of residual meter oil requiring special handling.  The new quantities are reflected in the attached ROOTS™ Meter Oil Application Chart.

    Roots High Pressure Cartridge Meter

    Dresser Roots Meters – Series B3-HPC Roots Meter
    High Pressure Cartridge Meters
    1M740/1480, 3M740/1480, 5M1480, 7M1480 MAOP HIGH PRESSURE METER

    Four models of High Pressure Cartridge ROOTS Meters incorporate new design innovations in rotary meter measurement.  These advancements to the time-tested and accepted ROOTS Meter provide measurement solutions over other obsolete positive displacement style meters,oversized inferential style meters, or less accurate styles of insertion inferential meters.

    Description

    Series B3-HPC High Pressure Cartridge Rotary Meters employ the same positive displacement operating principle in other ROOTS rotary meters where gas volumes are measured by two figure-8 impellers rotating in a chamber ofknown volume.  Precision machining to exact tolerances ensures measurementaccuracy,while materials of construction ensure measurement performance in the most severe conditions.

    1M and 3M measurement cartridges are interchangeable between their common body casting, as are the 5M and 7M versions. This allows the operatorto “right-size” the meter for a particular application. Also,accuracy certified cartridges are field replaceable for ease of maintenance.

    An optional full capacity internal Bypass is available for all Series B3-HPC cartridges. Since the Bypass is self-resetting, an optional electronic/mechanical differential pressure sensor with pulse output is available to indicate if the meterhas been in the Bypass mode.
