Applications
The Coriolis measuring principle operates independently
of physical fluid properties.
• Fluid temperatures up to +200 °C (+392 °F)
• Process pressures up to 400 bar (5800 psi)
• Mass flow measurement up to 1000 kg/h
(36.75 lb/min)
Approvals for hazardous area:
• ATEX, NEC/CEC, NEPSI
Connection to commonly used process control systems:
• MODBUS RS485
TI099D/06/en/04.10
71112154
Your benefits
The Cubemass DCI make it possible to simultaneously
record several process variables (mass/density/
temperature) for various process conditions during
measuring operation.
The transmitter concept includes:
• FieldCare for onsite operation and diagnosis
• Very low power consumption

Page 16: 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. -
