The Foxboro 144LVD is an intelligent transmitter that is designed to measure liquid level, interface or density of liquids. The measurement of the Foxboro 144LD is based on the Archimedes buoyancy principle. The Foxboro 144LVD can easily be supervised and configured remotely with a PC or Universal Handterminal. The Foxboro 144LVD can also be operated by using the local keys.
