ABB Glass tube variable area flowmeter Purgemaster FGM6100
Description
Overview
The ABB Purgemaster FGM6100 is a small glass-tube variable area flowmeter purpose-built for purging duty – keeping instrument enclosures, sample lines, and control line taps clear with a low, steady, visually confirmed purge flow. Its very low flow range of 0.53 to 2200 cm³/min on water and compact panel/wall/inline mounting format set it apart from ABB’s larger process variable area flowmeters such as the FGM1190, which serves general-purpose process flow measurement rather than purge duty.
Working closely with plant engineers in the region, Seven Star LLC proudly supplies the Purgemaster FGM6100 across Oman and the GCC, specifying it for analyzer houses, instrument enclosures, and sample conditioning systems that need a small, dependable, locally-read purge indicator, and backing every installation with genuine ABB hardware and full documentation.
Operating Principle
As with any variable area flowmeter, fluid flowing upward through a tapered glass tube lifts a float to a height proportional to the flow rate; the operator reads the flow directly off a scale etched on or beside the tube, with no electronics required for local indication. Scale options include direct-reading percentage scales for select configurations and a dt/df ratio scale in millimeters, with measurement accuracy rated per VDE/VDI 3513 from Class 2.5 on the longer 5-inch scale down to Class 10 on the more compact 3-inch and 1.5-inch scale lengths, depending on tube size and scale length selected.
The FGM6100’s tube and flow range are sized specifically for very small purge flows – from 0.53 to 2200 cm³/min on water – well below the range a general process rotameter like the FGM1190 is built to indicate accurately. An optional ring sensor (models RC10 or RC15) clamps directly to the meter body to provide adjustable minimum or maximum flow alarm signaling, integrating with switching amplifiers such as ABB’s KFD2, KFA5, or KFA6 series for a potential-free relay contact rated at 2A/250V AC.
Engineering Design of the Purgemaster FGM6100
The meter is built with a corrosion-resistant, high-strength stainless steel body and a quick, easy snap-in glass tube construction, protected by a safety-tested operator shield to contain the tube in the event of breakage – an important consideration given the meter’s typical placement near personnel in analyzer houses and control rooms. Optional inlet or outlet needle valves are available in low, medium, or high flow-capacity sizes, including DVGW-certified variants, giving operators local flow trim capability directly at the purge point without a separate valve fitting.
Float material options include glass, sapphire, Carboly, tantalum, or stainless steel to suit the purge media, and end connections are available in brass or 316 stainless steel with 1/4-inch NPT or BSPP female fittings. The unit is rated to 18 bar and 120°C, and mounts vertically, in-line, on a wall, or back-of-panel, giving installation teams flexibility to fit the meter into the available space in a crowded analyzer house or instrument enclosure.
Key Features
- Very low flow range purpose-built for purge duty: 0.53-2200 cm³/min (water).
- Quick, easy snap-in glass tube construction.
- Safety-tested operator protection shield around the glass tube.
- Corrosion-resistant, high-strength stainless steel body.
- Accuracy Class 2.5 to Class 10 per VDE/VDI 3513, depending on scale length.
- Optional ring sensor for adjustable min/max flow alarm signaling.
- Optional inlet or outlet needle valves in low, medium, or high capacity, including DVGW-certified variants.
- Vertical, in-line, wall, or back-of-panel mounting flexibility.
Industrial Applications
The Purgemaster FGM6100 is used in analyzer houses, instrument enclosures, sample conditioning systems, and control line purge points across Muscat, Sohar, Salalah, and the wider GCC, wherever a small, visually confirmed purge flow needs local indication without an electronic transmitter. The optional ring sensor alarm makes it suitable even where a low-flow purge condition must trigger a remote alarm rather than rely solely on an operator’s periodic visual check.
Seven Star LLC, as a trusted ABB supplier, distinguishes the FGM6100’s small purge-range format from the larger general-process FGM1190 (see related product), helping customers across Oman’s oil, gas, and process industries avoid specifying an oversized rotameter for a low-flow purge duty.
