SIMPLIFIES SENSOR SELECTION
Service package is offered to existing and potential users to assist them in specifying, installing and maintaining this company’s level sensors in a variety of applications. For a fee, the company will offer a site survey and pre-sale specification; evaluations and recommendations for the upgrade path; on-site training as well as hands-on training at the factory; installation and commissioning; scheduled periodic maintenance; and factory authorized repair services.
MAINTENANCE-FREE LEVEL SENSING
Application note titled “Float Gauge Maintenance Issues Solved with Non-Contacting Radar” discusses a buffer tank application that contains viscous fluid with vapors that leave a sticky coating and some turbulence. The solution for the application was installing a Rosemount 5400 Radar level transmitter with 6-in. cone antenna and 4-20 mA HART output.
