With its self-cleaning purge ports, the Model GF90 Flow Meter from Fluid Components International (FCI) maintains optimum flow measurement performance while reducing maintenance costs in rugged industry applications where dirt, grit and grime are present in the fluid.
The insertion style GF90 Mass Flow Meter's self-cleaning purge ports minimise maintenance requirements and costs in dirty gas applications.
In many process or manufacturing plants, technician access to flow meters for inspection or maintenance can be problematic due to their location.
By connecting the GF90's purge ports to compressed air, inert gas or solvent purge lines, process contaminants can be removed regularly and without un-installing the flow sensor element from the pipe to ensure continuous high accuracy measurement and significantly reduce maintenance activity.
The versatile GF90 utilises a thermal mass gas flow sensing element designed with 316 stainless steel and nickel-braze construction. It also can be specified with corrosion and abrasion-resistant alloys, including Hastelloy, Monel and tantalum, and with all-welded construction for service in the harshest environments.
It is available for service in broad range of fluid temperature applications, from -100 to 850degF (-73 to 454degC) and pressure applications to 1000 psig [69 bar (g)].
With constant power technology, the GF90 Flow Meter features turndowns from 1000:1, accuracy of +1 per cent of reading plus 0.5 per cent of scale, with repeatability of +0.5 per cent of reading or better.
Flow sensitivity is from 0.25 to 1600 SFPS [ft/sec at a standard temperature of 70degF and pressure of 14.7 psia] or 0.08 to 487.7 NMPS [m/sec at a normal temperature of 21.1degC and pressure of 1.013 bar absolute].
Combining rugged, low maintenance design with exceptional features, the GF90 is suitable for use in chemical plants, electric power utilities, oil/gas processing, pollution monitoring, steel, and wastewater treatment.
Typical flow measurement applications include: fly ash, flare gases, blast furnace gases, smokey cyclone separator air flow, landfill gases, digester and bio-gases, stack pollution monitoring and dirty gas in filter production.
