Pressure loss coefficients for Cubemass DCI
A0011692
Fig. 43: Pressure loss diagram for water
Pressure loss (US units) Pressure loss depends on the nominal diameter and the fluid properties.
The "Applicator" PC software is available from Endress+Hauser and can be used to calculate the
pressure loss in US units. The "Applicator" program contains all the important device data which
allows the measuring system arrangement to be optimized.
The software is used for the following calculations:
• Nominal diameter of the sensor with fluid properties such as viscosity, density etc.
• Pressure loss downstream from the measuring point
• Conversion of mass flow to volume flow etc.
• Simultaneous display of variables determined by different measuring devices
• Determining measuring ranges
The Applicator program runs on any IBM-compatible PC with Windows.
