Parker Fluid Control Division: A new line of Vortex Shedding Flow Meters offers meters that monitor the flow of cooling fluid for resistance welders, slurry pump seal water, machine coolant and steam boiler feed water. With no moving parts to clog or wear out, meters are well suited to monitor media with small particulates with uncompromised accuracy. Meters operate with NPT ports ranging from ¼”-2” in size and can handle flows from 4-200 gpm, with occasional over-ranging up to 125% of capacity without damaging the meter.
