Self-cleaning mass flowmeter reduces maintenance expenses in dirty gas applications

September 26, 2006

With its innovative self-cleaning purge ports, the Model GF90 Flowmeter from Fluid Components International (FCI) maintains optimum flow measurement performance while dramatically reducing maintenance costs in rugged industry applications where dirt, grit and grime are present in the fluid. The insertion-style meter’s self-cleaning purge ports minimize 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 utilizes 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 850 degrees F and pressure applications to 1000 psig.
