CI-ControlWave EFM Product Features & Overview / 1A-1
Section 1A
PRODUCT FEATURES & OVERVIEW
1A.1 PRODUCT OVERVIEW
ControlWave products have been designed and integrated as a highly adaptable, high
performance Distributed Open Controller family with exceptional networking capability
that provides a complete Process Automation Management Solution. ControlWave EFM
electronic flow meters have been designed with an emphasis on providing high performance
with low power consumption, scalability and modularity. ControlWave EFM Base
Housings support up to 2 I/O or 6 I/O Modules (4-Slot and 8-Slot Housings respectively).
ControlWave EFM electronic flow meters have been designed as an ideal platform for
remote site automation, measurement and data management within the oil & gas industry.
ControlWave EFM units are extremely effective in Flow Computer, Process Controller or
Remote Terminal Unit capacities as follows:
API 21.1 EFM/Flow Computer application
ControlWave EFM units offer a cost effective and competitive match to all industry meters
used in Electronic Flow Measurement and Flow Computer installations.
- For orifice and other differential meters, ControlWave EFM has been designed to
integrate a DP/P/T, smart Multivariable Transducer with excellent per-formance over
the full range of operating pressure and temperature conditions.
- For linear meters, such as turbine and ultrasonic meters, ControlWave EFM doesn’t
overlook the importance of pressure and temperature corrections and utilizes smart
P/T circuitry to provide high accuracy over the full range of operating conditions.
Process Controller or Remote Terminal Unit (RTU) applications
Process Controller and RTU applications don’t suffer performance limitations of flow
computers with expanded hardware. User configurable I/O Modules provide AI/O, DI/O and
HSC functionality. Up to two Expansion Communication Modules (2 RS-232 & 1 RS-485
Port, each) can be added to a ControlWave EFM.
