The GF90 Flow Meter 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 flowmeter's self-cleaning purge ports minimize maintenance requirements and costs. The meter utilises a thermal mass gas flow sensing element designed with 316 stainless steel and nickel-braze construction. It is available for service in broad range of fluid temperature applications, from -73 to 454ºC and pressure applications to 69bar(g). It featuresturndowns from 1000:1, accuracy of +1 percent of reading plus 0.5 percent of scale, with repeatability of +0.5 percent of reading or better. The meter includes an advanced microprocessor-based programmable transmitter, that can store up to three calibration groups. The instrument is also inherently multi-variable, providing both flow and temperature measurements without any additional tap points. The transmitter electronics are addressable via a built-in LCD display and keypad or through its RS-232C and RS-485 serial ports. The serial I/O ports supportaccess to computers or ASCII terminals.
