Pressure loss (US units)
Pressure loss is dependent on fluid properties nominal diameter. Consult FMC Technologies 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 measuring system.
The software is used for 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 size.
• Determining measuring ranges.
The Applicator runs on any IBM compatible PC with windows.
