Product Description:
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. For maintenance the sensor is easily retracted from the fuel line through a full-port ball valve. The retractable fitting allows an adjustable insertion depth to optimize positioning of the sensor in the line and fitment to pipes of varying diameters.

A typical mounting is via a 1” NPT pipeline nipple, and through a 1” Full port Ball Valve. The sensor connects directly to the Ball Valve using an adaptor. We recommend a suitable ball valve is sourced locally to suit pipe fittings. ANSI and DIN type Flange mounts are also available. Please select adaptor type from Accessories when ordering.
