The online particle counter PAMAS S50P Fuel is used as a fixed-installed measuring instrument for condition monitoring and contamination analysis of liquid fuel. The instruments measure the particle number in eight different size channels and early alerts in case of failures caused by bigger particle sizes (e.g. corrosion). Due to this feature, the particle analyzing system PAMAS S50P Fuel is indispensable for preventive condition monitoring of liquid fuel, as it prevents the filling of contaminated fuel into the tank. On its 6-digit LED display, the instrument reports the triple code according to ISO 4406. The PAMAS S50P Fuel is equipped with a pump controlling the flow rate to 25 ml/min at a pressure range from 0 to 6 bar
