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

The turn-down capability from Qₙₒₘ 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
