For more than 50 years LINC Level Switch has been used in oil & gas, energy, petro-chemical, chemical, industrial manufacturing, construction, mining and water and wastewater treatment industries.
LINC level and flow switches monitor a variety of liquids and provide a pneumatic or electric signal to activate alarms, operate valves, or start and stop pumps. These level controls have outperformed in the toughest customer applications around the world – at vital infrastructure projects and manufacturing sites, and within a vast array of deep-sea rigs and distribution sites that keep supplies of gas and oil flowing.
All LINC level and flow switches are made to order of 316 stainless steel with a variety of sizes and configurations.
