Subsequent injection of antistatic agents using LEWA metering systems

Pumping fuels in pipelines over long distances carries a high risk of electrostatic charge due to frictions in the pipeline. In order to avoid a momentous explosion, a small amount of antistatic additive is added to the fuel to increase its conductivity. In that process, the correct volume flow plays a decisive role.

By continuously comparing the actual and target volume flow, LEWA metering systems enable safe and reliable pumping of fuels – e.g. kerosene.


Safe pumping of fuels through metering of antistatic additives using LEWA metering systems

  • Autarkic closed loop system
  • Self-monitoring and regulating system: The conductivity of the fuel is continuously measured and monitored by means of appropriate instruments or sensors
  • LEWA smart control
  • Fast achievement of the desired concentrate, no long settling times
  • Coverage of a large control range
  • Mixing tank with electric agitator
  • Drip trays for 100 % of the system’s capacity
  • Leakage control, level indicator, flow meter, check and shut-off valves
  • High quality materials such as stainless steel 316/316L (1.4401/1.4404)
  • Consideration of common legal norms and standards (ATEX, WHG, TA-Luft)


Every material or object contains positive and negative electrical charges. Normally, the electrical charges are balanced out. The object is electrically neutral. An electrostatic charge occurs when the object is moved. The charge arises from a contact or friction between two objects and a subsequent separation. The process is referred to as a triboelectric effect or as tribo-electricity. There is an electron transfer from one material or substance to another. The effect occurs both for solids and liquids.

Due to the low conductivity of fuels, the described effect occurs at conveying substances such as gasoline, petroleum or kerosene. If discharge sparks form, this can lead to a fatal explosion in an appropriate atmosphere. The consequences range from the loss of the product through the destruction of equipment and machinery to the mortal danger of people working in the vicinity of the pipeline.

For this reason, a small amount of antistatic agent is added to the fuels. Antistatic additives reduce the risk of electrostatic charge by improving the dissipation of excess electrical charges.

LEWA metering systems ensure a correct addition of antistatic agents to set the fuel’s conductivity. Often only extremely small amounts are required. A diluted antistatic agent solution can then be provided in a mixing container. The diluted solution is added from the mixing container into the fuel pipeline in small quantities. Using appropriate instruments and a control cabinet with LEWA smart control, the conductivity of the fuel in the pipeline is constantly monitored and, if necessary, re-adjusted in a closed loop.
