pH is measured at the discharge of the API separator in refineries to enhance efficiency of secondary waste treatment processes, such as flocculation. During this process, the pH sensor often becomes coated due to emulsified oil, resulting in frequent cleanings and a short sensor life. The Rosemount™ 396P pH Sensor is designed with a coating-resistant reference junction to reduce cleaning and provide maximum sensor life in API separators.
The Rosemount 5081 Explosion-Proof Transmitter is a single channel loop powered device that can accept input from a variety of liquid analysis sensors including: pH/ORP sensors, conductivity sensors (contacting and toroidal) and amperometric sensors (dissolved oxygen, chlorine and ozone). The transmitter features a rugged, weatherproof, corrosion-resistant enclosure to withstand harsh environments.
