Ametek BW Controls offers an extensive line of sensors for Point and Continuous Liquid Level Control. Ametek BW Controls uses the same advanced magnetostrictive technology as in GEMCO products providing high accuracy and reliability for continuous liquid level measurement. Continuous level sensors are used in industries such as chemical processing, food and beverage, pharmaceutical and petroleum. Point Level is used in municipal water and wastewater applications. The advantages of conductivity control over mechanical control include fewer mechanical problems, ease of installation, and operational efficiency that is immune to changes in pressure.
