American Rosemount was established in 1956 and is a famous brand of Emerson in the United States. Rosemount was acquired by Emerson Electric Company in August 1976. Rosemount's products include pressure, temperature, flow, level and safety measurement instruments. Throughout the process control industry, Rosemount process instruments have a wide range of applications.
Rosemount measurement technology helps customers shorten project execution cycles and reduce costs. It also helps customers improve equipment uptime, reduce power generation costs, reduce fuel costs, and enhance environmental friendliness throughout the life cycle of the instrument.
Rosemount conductivity meters include the following models,
● Rosemount 400 Contacting Conductivity Sensor
● Rosemount 228 Toroidal Conductivity Sensor
● Rosemount 140 Retractable Conductivity Sensor
