From its Enraf office in Delft, The Netherlands, Honeywell announced the release of the first ISA100.11a-ready wireless instrument, the ‘FlexLine Wireless Radar Gauge.’ In addition to level measurement, the gauge can track temperature, pressure, water and overfill, eliminating the need for multiple gauges and transmitters.

The ISA100.11a standard provides a wireless industrial process automation network to address control, alerting, and monitoring applications plantwide. It focuses on battery-powered field devices with the ability to scale to large installations and addresses wireless infrastructure, interfaces to legacy host applications plus security, and network management requirements in a functionally scalable manner.

The new instrument is called “FlexLine Wireless Radar Gauge.” Honeywell says it potentially will improve operator awareness by capturing a wide array of tank measurements and quickly transmitting them via the OneWireless™ network to control rooms. This reduces overall operating costs and improves safety by eliminating the need for manual data collection.

The gauge is the latest addition to Honeywell’s growing OneWireless family of industrial wireless solutions for the process industries. Based on equipment compatible with the ISA100.11a standard, OneWireless networks can simultaneously accommodate multiple wireless protocols and thousands of field devices ranging from transmitters and gauge readers to mobile handheld devices and RFID tags.

Because the instrument also tracks temperature, pressure, water and overfill, it eliminates the need for multiple gauges and transmitters, which further reduces installation costs and increases flexibility by enabling new measurements without additional wiring.

Honeywell says the gauge has passed the “highest accuracy and security standards” set by The Dutch Weight and Measurement (W&M) authority, a key designation for the device to be used for loading and unloading tank liquids from ships and trucks. In addition to meeting the Dutch standards, the gauge has been submitted for review by W&M authorities in several other countries.

 “Terminals today are striving for more efficient production, which means operators need more information and diagnostics from the field to better understand how their assets are functioning,” said John Joosten, radar and safety product manager, Honeywell Enraf.

“The FlexLine Wireless Radar Gauge enables plants to easily obtain this information, making the device an ideal solution to increase uptime, efficiency and safety for facilities with challenging infrastructures.” He says FlexLine Wireless combines new algorithms with Honeywell Enraf’s planar antenna technology, to ensure a high level of precision, which is  demanded for custody transfer accuracy.

The instrument maintains its ultrahigh performance level even in the most challenging circumstances, like dome roofs and on bad stilling wells. The Enhanced Performance Signal processing makes it possible to provide accurate level reading even when a free space antenna is installed close to the tank shell.
