Useable for water and/or chemical flow measurement, the company’s oval wheel flowmeters are positive displacement flowmeters where the passage of liquid causes two oval gears to rotate within a precision measuring chamber and with each rotation a fixed volume of liquid passes through the meter. Magnets embedded within the gears initiate a high resolution pulse train output. This technology allows precise flow measurement and dispensing of most clean liquids regardless of their conductivity, with other liquid characteristics having no or minimal effect on meter performance. According to the company, positive displacement flowmeters are an inexpensive means to accurately meter many high viscosity liquids as high as one thousand centipoise.
