New transmitter intrinsically safe, explosionproof
New FCX Series electronic transmitters feature compact size, premium performance, intrinsic safety, and explosionproof design.
From sealed sensing systems to high-powered RTUs, for uses ranging from natural gas to cryogenic liquids, FCX Series transmitters measure, display, alarm, and output level, pressure, and flow data.
Gauge, absolute, differential pressure, flanged level, and remote seal models are available in AII series transmitters, while gauge and differential pressure models are offered in AIIe series.
The AII series transmitters feature accuracy to ±0.07% of span, stability of ±0.1% URL for 3 years, and a response time to 40 msec.
AIIe series transmitters have an accuracy to ±0.1% of span and stability of ±0.2% URL for 3 years. Turndown is 100-to-1 (AII) or 30-to-1 (AIIe). FCX transmitters communicate in HART and Fuji protocols.
A simple electronic upgrade in the field will convert the standard AII output for compatibility with IEC Foundation Fieldbus and Profibus specifications.
A single silicon crystal is at the core of the transmitter.
This microcapacitance sensor design eliminates the effects of hysteresis and long-term fatigue.
In addition, floating cell construction incorporates an overrange protection diaphragm that isolates the sensor from adverse conditions present in normal process applications.
Materials of construction for metallic wetted parts include 316 SS, Hastelloy, Monel, and Tantalum. The enclosure is rated IEC IP67 and NEMA 6/6P.

Literature discusses emission-free gas processing
New free literature describes a field proven quantum leap technology (QLT) process that recovers all BTEX and other hydrocarbon emissions and can be applied to upgrade existing dehydrators in the field.
Return on investment is achieved by collecting condensed hydrocarbons and reducing reboiler fuel expenses by 50% or more, the literature says.
QLT does not involve flares, thermal oxidizers, or gas stripping. Unit size and weight are comparable with conventional dehydration systems.
The literature says emissions free QLT is applicable and could benefit large process plants as well as offshore production operations.
Common questions are answered as well as a detailed description of the process benefits.

Unit controls flow rates for multiple gases
The new Smart-Trak digital mass flow controller controls flow rates for multiple gases. The instrument's Dial-A-Gas feature and pilot module interface are used to change gases and other parameters in the field. The Smart-Trak microprocessor is programmed for 10 gases that are commonly used. Other gases may also be specified to create a custom instrument.
The Dial-a-Gas function is available via PC or six pushbuttons on the pilot module. Mounted directly on the instrument, or remotely as far as 50 ft from the controller, SmartTrak's pilot module interface offers a small, convenient, and easy-to-use package, the company says.
The instrument's 1 by 3 by 5 in. footprint permits easy drop-in replacement for any mass flow controller, the firm points out. For remote monitoring, it provides digital and analog control without complex wiring or control electronics. An RS232 output and two user-selectable analog outputs are available from the device.
The Smart-Trak control valve compensates for a variety of temperature and pressure variations in the gas stream. User-selectable operating modes—including closed, normal, and purge modes—are controlled from the pilot module or via a remote signal. Users can also adjust response characteristics for multiple applications or system pressure design modifications.
The all-stainless steel instrument is suited for any clean gas flow, including toxics and corrosives.
