Pressure tightness
Measuring tube: 0 mbar abs (0 psi abs) with a fluid temperature of
60 °C (140 °F)
Limiting flow
The diameter of the pipe and the flow rate determine the nominal diameter of the sensor.
The optimum flow velocity is between 2 to 3 m/s (6,56 to 9,84 ft/s). The velocity of flow (v), moreover, has
to be matched to the physical properties of the fluid:
• v < 2 m/s (6,56 ft/s): for abrasive fluids such as potter's clay, lime milk, ore slurry etc.
• v > 2 m/s (6,56 ft/s): for fluids causing build-up such as wastewater sludges etc.
Pressure loss
• No pressure loss if the sensor is installed in a pipe with the same nominal diameter.
• Pressure losses for configurations incorporating adapters according to DIN EN 545
