Pressure loss is dependent on the fluid properties and nominal diameter. Consult Endress+Hauser
for Applicator PC software to determine pressure loss in US units. All important instrument data is
contained in the Applicator software program in order to optimize the design of the measuring
system.
The software is used for the following calculations:
• Nominal diameter of the sensor with fluid characteristics such as viscosity, density, etc.
• Pressure loss downstream of the measuring point.
• Converting mass flow to volume flow, etc.
• Simultaneous display of various meter sizes.
• Determining measuring ranges.
The Applicator runs on any IBM-compatible PC with Windows.
