Mechanical Construction

Sensors are manufactured with two internal measurement tubes arranged side by side. In parallel or dual path sensors (order code Pxx), these tubes are connected in parallel and the flowing fluid is split equally between them. In serial or single-path sensors (order code Sxx), the internal tubes are connected end to end, creating a single path through which all fluid flows.

Manifold designs have a removable inlet/outlet manifold block and utilize selectable seals between the manifold and sensor body. In sealless designs, the measurement tubes are continuous between the process connections and do not have seals. Manifold designs offer shorter delivery lead times and may have a lower pressure drop than sealless designs for the same flow rate.

Performance Data

Flow Measurement Uncertainty
- Selected Sensors down to ±0.05 % 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 ±0.0035 kg/liter

Uncertainties and Flow Measurements Turn-down

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

For flow Q ? ZP stability / (Base Calibration uncertainty/100) ? u = calibration uncertainty
For flow Q < ZP stability / (Base Calibration uncertainty/100) ? u = (zero stability/Q) * 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/cm³ per bar. Compensation is possible by pressure sensor input (analog input or digital write) or manual value entry into the transmitter.

Premium Plus, Ultimate, Low Flow, and Enhanced Density Calibration come with Gold Line sensors and are not available in all materials, pressure, and temperature ranges.

Reference conditions: 18-24°C Water @ 1-3 bar; Gas (Natural gas) 35-100 bar.

Measurement Tube Pressure Ratings

The maximum pressure (p???) of a sensor is determined by its lowest-rated part. The lowest rated part can be either the measurement tube (p??? indicated below), the connection block/manifold (p??? indicated in the mechanical construction section), or the process connection (for p??? see published standards or manufacturer information).
