High Pressure In-line Conductivity Sensor (IECEx Req.) (D2 JF-1A model) - 99506-0

ASTM D2624

An inline system that provides real time measurement of conductivity in pipelines using high accuracy AC measurement technology according to ASTM D2624.

The system can be connected to a refinery/terminal management system to provide an automatic and continuous record of product conductivity levels, eliminating the requirement for manual sampling and record keeping. When installed with an automatic dosing system the in-line sensor allows automated additive dosing to maintain the conductivity within specified limits.

The conductivity sensor comprises two stainless steel coaxial electrode sensors and is suitable for long-term immersion in fuels.
