Flow transmitter rangeability

WebTurndown ratio is also commonly referred to as rangeability. It indicates the range in which a flow meter or controller can accurately measure the fluid. In other words, it's simply the high end of a measurement range compared to the low end, expressed in a ratio and is calculated using a simple formula: Turndown Ratio = maximum flow / minimum flow WebKey Features: Direct mass flow measurement of air and gas. Excellent low flow sensitivity with high turndown (rangeability) Process temperatures to +400 °F (+200 °C) Rotatable housing. FM / FMc / ATEX / IEC approvals. Resettable and non-resettable totalizers. Calibration verification in the field.
