Designed to perform in challenging lubrication environments, Variable Area Vane and Piston Style Flowmeters come in 12 sizes with pressures up to 2,000 psi for flows up to 500 gpm. HART digital communication signal is superimposed on top of 4–20 mA standard analog signal, which provides additional digital information to controller. Optional mechanical switch is available to back up transmitted signal. Meters mount in-line and in any orientation, with no straight pipe runs required.
