Seta Multi Filtration Tester (MFT) - 91600-4

ASTM D2068
ASTM D8386
IP 387
CGSB-3.0 No.142

The Seta Multi Filtration Tester (MFT) is a fully automated instrument, designed to test the Filter Blocking Tendency (FBT) of diesel, biodiesel (B100 & B5/7/20/30), gas oil, gas turbine fuel and kerosene.

The MFT features a colour touch screen and clear, simple user interface which guides the operator through the menu system and simple operating sequence. Results are stored internally and can be viewed on the screen or saved directly to a USB memory stick or LIMS for further data management and analysis. Alternatively, a printer can be connected using the RS232 serial port.

Designed to be compact and lightweight, the MFT's small footprint makes it ideal for laboratories with limited bench space.

FBT analysis is achieved by measuring the pressure differential across a disposable filter. Fuels which have a high FBT could potentially block filters in the distribution network or during use in a vehicle or power plant.

MFT is also used to determine the FBT for BX fuels containing bio components, such as FAME (biofuel), which have been ‘cold soaked’ at a temperature just above zero Celsius. During the 16 hour cold soak particles of saturated monoglycerides (SMG’s) and sterol glucosides can be formed which do not dissolve when the temperature is raised back to ambient.

Seta Multi Filtration Tester (MFT) - 91600-4


  • Fully automated test
  • Interlaboratory study proven with ASTM and EI validated precision
  • Large colour touch screen display
  • Graphical display of sample flowrate

  • RS232 interface for printing
  • Simple calibration/verification



The fuel sample is drawn from the integral fuel reservoir by the pump, and an efficient pulse damper provides smooth and continuous flow. The pressure and temperature of the fuel are continuously monitored while it is pumped through the specified filter into the waste container. The recorded pressure rise, or the volume of pumped sample that causes a specified pressure to be exceeded, are used by the microprocessor to calculate the test result. Standard tests use 300 ml of fuel pumped at 20 ml/min.

Calibration and verification:
Calibration of the MFT can be performed in the field, eliminating the costs and time associated with sending the instrument to a service centre.

Service and maintenance:
The rugged design ensures minimal operational maintenance is needed.Suppled with: Mains lead, Fuel beakers and instruction manual.
