Modernizing Tank Gauging Systems via Emulation

Jim Cahill

Here in the US, we read many stories of oil tanks being filled to the brim with increased production from shale sources and federal law barring export. Whether in the US or anywhere across the globe, managing and reporting on the levels in these tanks require accurate measurement. Also, given the importance of these measurements in safety and environmental protection, accuracy and reliability is required, especially for…

WirelessHART Join Key Interoperability and Problem Solving

Jim Cahill

Author: Craig Abbott Recently, a customer using a non-Emerson hand held communicator ran into problems during FAT. None of the devices they had configured would connect to the Rosemount 1420 gateway whilst other devices, configured by our technician using a 475 hand held communicator worked perfectly. WirelessHART, now recognised as the IEC62591 standard, supports interoperability, […] Read the full text.
