Elster enCore FC1 Flow Computer – Honeywell Oil & Gas

Name: Elster enCore FC1 Flow Computer – Datasheet & Price Quote
Brand: Elster

Description

Overview

The Elster enCore FC1 is a high performance flow computer for oil and gas measurement applications, designed for gas and liquid measurement duties and the corresponding calculation algorithms. The name enCore, meaning Honeywell Elster new Core, refers to the backbone of the FC1 which carries the basic functionalities. A modular software system made of independent application function blocks (AFBs) turns the FC1 into a reliable, secure and high performance flow computer, and the same modularity in hardware means the widest range of applications can be covered.

Engineering and Design

The enCore FC1 implements the widest range of calculation algorithms pursuant to AGA, ISO and API standards to fulfil all requested flow conversion requirements on natural gas and liquid streams. Multi-stream functionality and advanced logging properties are available, and the user-definable logging feature can use any desired amount of flash memory, so there are no restrictions in logging depth. By using cryptographic mechanisms, the unit can be securely updated and upgraded, even in a fiscal way.

Two housing sizes are offered: a one-third design width of 19 inches and a one-half design width of 19 inches, which differ in the number of I/O and communications boards (4 board slots versus 7 board slots). Input boards with integrated Ex-barriers allow small stations to be equipped with a high-end flow computer. The MFE7 input board provides seven multifunctional inputs (PT100, 4-20 mA or HART, digital pulse and status, and an RS485 channel), while the MFA8 output board provides digital and 0/4-20 mA analogue outputs. Predesigned device drivers connect analyzers, ultrasonic meters and transmitters, and the PC software offers Normal mode and Expert mode configuration.

The FC1 supports liquid measurement, PID control, turbine lubrication monitoring and soft PLC functions as application modules, widening its use from gas metering to station control. With its predesigned device drivers the FC1 connects to analyzers, ultrasonic meters and transmitters directly, and the service interface allows secure remote access for configuration and diagnostic work. The FC1 hardware can be ordered with integrated Ex barriers for small stations, reducing cabinet complexity, and the USB front panel port gives service engineers a fast configuration path at the site without opening the cabinet.

About brand

Elster is a gas metering and combustion control brand founded on 1 October 1848 in Berlin, where it began by making gas lamps. It built a factory in Mainz in 1876 and later merged with the Dutch flow specialist Instromet in 2005. Melrose bought the Elster group in 2012, and Honeywell acquired it in 2015–2016, so Elster products are now sold by Honeywell.
Seven Star LLC sources and supplies Elster ultrasonic flow meters, gas flow computers and station communication units for pipeline and utility operators in Oman.

Ordering Elster meters and flow computers: what we need

For an ultrasonic meter: nominal size, pressure rating and flange standard, flow range, gas composition, operating pressure and temperature, the metrological approval required and the flow calibration expected. For a flow computer: device type, the serial number and software version of the existing unit, the I/O boards fitted, the meters and transmitters connected, the conversion and compressibility method (for example AGA 8) and the communication protocols. A photo of the type plate and the parameter printout shorten the check against the manufacturer's documentation considerably.
