Aging infrastructure, increasing installation cost, along with efforts to optimize work force are causing the industry to find more ways to use WirelessHART. WirelessHART has been around for almost a decade and has proven itself safe and reliable for indication. Now users are looking expand the use of wireless in their facilities by implementing discrete ON/OFF control using WirelessHART communications. In this video, I will review a quickly growing industry trend of tank farms and terminals using WirelessHART with electric actuation.
