Rose mount Mass Low Transmitter 3095 Series

Detailed Product Description

The Leader in MultiVariable Mass Flow Measurement.
Rosemount delivers a tradition of excellence and technology leadership, featuring the state-of-the-art Rosemount 3095 MultiVariable Mass Flow
transmitter. The Rosemount 3095 delivers four measurements from one coplanar device with unmatched operating performance, including
dynamic fully compensated mass flow. Engineered to combine best products with best installation practices, the Rosemount 3095 enables a
complete offering of DP Flowmeters.
1.0% of Mass Flow rate accuracy over
10:1 flow range
Enabled by superior sensor technology and engineered for optimal
flow performance, the Rosemount 3095 delivers unprecedented
±0.05% of DP reading reference accuracy, resulting in mass flow
accuracy of ±1.0% over 10:1 flow range. Superior performance
means reduced variability and improved plant safety.
Ten year stability of ±0.25%
Through aggressive testing, the Rosemount 3095 has proven its
ability to maintain unprecedented performance under the most
demanding conditions. Superior transmitter stability decreases
calibration frequency for reduced maintenance and operation costs.
Unprecedented reliability backed by a limited
12-year warranty
Further enhance installation practices with the most reliable
platform supported by a 12-year warranty.
Four variables in one device
The advanced Rosemount 3095 measures three process variables
simultaneously and dynamically calculates real-time fully
compensated mass flow. One transmitter means reduced process
penetrations, inventory and installation costs.
Real-Time fully-compensated mass flow
Fully compensated mass flow reduces sources of traditional DP
flow uncertainty. Rosemount 3095 calculates Mass Flow by
measuring process pressure and temperature to perform real-time
calculation of all flow equation parameters including density,
viscosity, velocity, Reynolds number, beta ratio, discharge
coefficient, velocity of approach, and the gas expansion factor.
Superior flow calculations yield more accurate measurements to
reduce variability and increase profitability.
Coplanar platform enables DP flowmeters
The flexible coplanar platform allows integration with the complete
offering of Rosemount primary elements for any flow application.
The solution arrives factory calibrated, pressure-tested, and ready
to install right out of the box. Only Rosemount has a scalable
coplanar transmitter design to reduce engineering and inventory
costs.
Advanced PlantWeb functionality
From multiple process variable generation to
advanced compensated Mass Flow functionality and
highly integrated flowmeter solutions, the 3095
reduces operational and maintenance expenditures
while improving throughput and utilities
management.
