Electromagnetic insertion type flow meters are designed for use with conductive liquids in 25 to 305 mm (1 to 12") pipe. A choice of materials (stainless steel, brass, and PVC) allows the meter to adapt to a range of temperature, pressure, and corrosive environments. The FMG980 is highly suitable for difficult applications with changing viscosities and pulsating flows, such as air-driven diaphragm pumps. With no moving parts, these meters can be used in “dirty” applications where debris would foul a mechanical meter. Like all magmeters, when used in chemical injection applications, these meters should be installed upstream of the chemical line (or far enough downstream to allow complete mixing of fluids before the meter). Designed for modularity and versatility, the FMG980 Series has a current-sinking pulse output that can be combined with a transmitter or indicator. For analog output and display of rate and total, an FMG980 display can be used. Blind analog output is provided by the FMG-1000-MAW. FMG980 Series fixed depth insertion meters require special fittings for installation.
