Shell Water Detector

USADO PARA DETECTAR ÁGUA NÃO DISSOLVIDA FINAMENTE DISPERSA EM JET A-1 / QAV-1. 

FORNECE UMA  INDICAÇÃO POR COLORAÇÃO QUANTO A PRESENÇA DE ÁGUA MESMO COM NÍVEIS DE CONCENTRAÇÃO ABAIXO DE 30 PPM

Procedimento de Teste
  • Examine a capsula. Confirme cor amarela uniforme do papel.
  • Coloque a capsula na seringa.
  • Inserir seringa aprox pela metade de seu comprimento no recipiente de amostra.
  • Retire exatamente uma amostra de 5ml. através da capsula.
  • Examine a capsula para a mudança de cor.
  • Uma coloração verde indica a presença de contaminação por água.
  • Se falhar o teste na amostra retirada da entrada do filtro, notifique imediatamente a companhia aérea e retire uma amostra da saída do filtro e repita o teste. 
  • Se falhar o teste, avise imediatamente o representante da companhia aérea. 

  Shell Water Detector
USED FOR DETECTING FINELY DISPERSED UNDISSOLVED WATER IN JET FUEL. A DISTINCT RESPONSE IS GIVEN FROM LEVELS BELOW 30 P.P.M.  

Test Procedure  

  • Examine capsule. Confirm uniform yellow paper colour.
  • Fit detector capsule to syringe.
  • Immerse capsule and approximately half of syringe in sample.
  • Draw exactly 5ml. through capsule.
  • Examine capsule for colour difference.
  • A distinctive or mottled green colour gives positive indication of water contamination.
  • If fail, on inlet side advise supervisory staff, and take fresh sample from outlet side of filter.
  • If fail, advise aircraft representative immediately.  

 
 

The Shell Water Detector is a device for determining the presence of finely dispersed undissolved water in jet fuels at concentrations lower than those normally detectable by visual examination. Water dispersions of this type can result from the emulsification of a water/fuel mixture during pumping or from precipitation of dissolved water due to a fall in fuel temperature.

Why is it important to use the Shell Water Detector?

Ensuring that jet fuels are free from dispersed or free water is a crucial part of the quality assurance process. All jet fuels contain some dissolved water which invariably comes out of solution as the fuel cools during high altitude flights. Aircraft fuel systems are designed to deal with these trace amounts and normally no operational problems are encountered. In addition to this dissolved water, jet fuels can contain significant levels of dispersed water.

The Shell Water Detector is a reliable, convenient and cost effective means to verify that the concentration of this dispersed water is below the IATA recommended limit of 30ppm. If higher levels of water are loaded with jet fuel it is possible that aircraft safety could be compromised

Because the fuel systems are not designed to handle unusually high levels. On aircraft many systems, such as engines, are duplicated or even triplicated for safety reasons. There is however usually only one supply of jet fuel. Consequently, if there was anything wrong with the fuel it could cause catastrophic results. It is therefore essential that only clean, dry, on-specification fuel is delivered on to aircraft.

The Shell Water Detector is one of many products developed by Shell for the aviation industry. Shell has been closely associated with the development of oils greases and fluids for aircraft applications since the earliest days of aviation. Today, the AeroShell brand name is one of the best known within the aviation industry. Shell has developed products to meet every significant engine and airframe requirement for lubricants, and the range continues to be extended to meet the performance needs of tomorrow's aircraft.
