Flow meter selection for unknown minimum or maximum conditions or for future expansion shouldn’t require compromising accuracy or a costly replacement. Target technology from Aaliant Fluid Measurement Solutions, of Spartanburg, S.C., allows a simple replacement of the target to achieve range changes of up to 70:1 turndown with the same meter. This flexibility, combined with the meter’s ability to be field calibrated without flow testing, makes the target flow meter an ideal choice for most applications.
