Performance Data

Flow Measurement Uncertainty
- Selected Sensors down to ±0.10 % ¹ of rate (Gold Line)
- Standard Sensors down to ±0.15 % ² of rate
Flow Measurement Repeatability
- Down to ±0.05 % of rate
Temperature Measurement
- Better than ±1 °C
Density Calibration (Liquid)
- Selected Sensors down to ±0.0005 kg/liter (Gold Line)
- Standard Sensors down to ±0.001 kg/liter
Measurement Tube Pressure Ratings
- Its lowest-rated part determines the maximum pressure (Pmax) of a sensor. The lowest rated part can be either the measurement tube (pmax indicated below), the connection block/manifold
  (pmax indicated in the mechanical construction section) or the process connection (for pmax see published standards or manufacturer information).

Uncertainties and flow measurements turn down

All uncertainty statements refer to reference conditions – the mass flow of water, 18 – 24 °C, 1 – 3 bar in a standard temperature, pressure, and material configuration sensor. The sensor can be used to measure gas – uncertainty values for gas equal to the liquid value plus 0.3 %. Reference conditions for gas are mass flow of natural gas, 18 – 24 °C, 35 to 100 bar in a standard temperature, pressure, and material configuration sensor.

The turn-down capability from the Qnom of the flow sensor is mainly driven by its zero-point stability. At the very low end of the measuring range, the uncertainty (u) is dominated by the zero point stability. The zero point stability of a standard sensor is 0.000036 kg/min (0.000079 lbs/min). The zero stability of a Gold Line sensor is 0.000019 kg/min (0.000042 lbs/min).

For flow Q ? zero stability / (calibration uncertainty/100) u = calibration uncertainty
For flow Q < zero stability / (calibration uncertainty/100) u = (zero stability/Q) x 100

Uncertainties from environmental and process conditions

If sensors are not zeroed at operating conditions, minor additional uncertainties can arise from elevated temperatures and pressures: ±0.00308 % of maximum flow per °C and ±0.0208 % of maximum flow per bar.
Process temperature effect on density: additional uncertainty of ±0.000641 g/cm³ per °C difference from calibration temperature with standard density calibration and of ±0.000073 g/cm³ per °C difference from calibration temperature with enhanced density calibration. This effect can be mitigated by a simple field density adjustment at operating conditions.
Process pressure effect on mass flow: The effect of pressure on flow measurement is 0.001 % of the rate per bar. Compensation is possible by pressure sensor input (analog input or digital write) or manual value entry into the transmitter.
Process pressure effect on density: The effect of pressure on density measurement is 0.00012 g/cc per bar. Compensation is possible by pressure sensor input (analog input or digital write) or manual value entry into the transmitter.
