MLA1000 Continuous In-line Conductivity

Product

Petroleum products with low electrical conductivity can become electrostatically charged at high flow speeds and may ignite as a result of a spark. Additives are therefore added to kerosene (Jet-A-1) and light mineral oils to increase conductivity in order to dissipate the electrostatic charge to the tank or pipeline wall. Precise metering of the additive in accordance with the actual conductivity level is now possible thanks to constant conductivity measurement using the MLA1000. The 4-20mA current conductivity signal controls the additive metering pump fully automatically.

The measurement system utilises the flow speed within a pipeline
Although a comparatively strong flow of 0.5 – 7 m/s occurs within the pipeline itself, the flow speed within the measuring probe is reduced through the small size of its in-flow and out-flow openings. Accordingly, the resulting laminar flow between the two electrodes within the probe permanently suppresses polarisation, yielding highly accurate, real-time conductivity and temperature values.

MLA900 Individual Conductivity

Product

Liquids with a low electric conductivity can become electrostatic charged. If these liquids are combustible, the danger of an inflammation or even an explosion exists – especially if the electric charge discharges through sparks.In petroleum products like kerosene, diesel, fuel oil and many other industrial liquids, the conductivity can be increased by additives. The MLA900 measures the conductivity of the liquid and therefore judges whether the quantity of the additives is sufficient enough. This way, the required conductivity minimum values can be safely maintained. The MLA900 is applied for the use in areas of potentially explosive atmosphere and approved as a standard-measuring-method after ASTM D2624.
