Filter Blocking Tendency (FBT)

ASTM D2068, ASTM D7501, IP 387

The Filter Blocking Tendency-tester (TFBT) is an automated instrument designed to test the Filter Blocking Tendency (FBT) of distillate fuels including diesel, biodiesel (B100 & B5/7/20/30), gas oil, gas turbine fuel, and kerosene. It conforms to ASTM D2068 and IP 387. It can automatically measure and calculate FBT (Filter Blocking Tendency) and FQF (Filterability Quality Factor).

The fuel sample for this test is drawn from the integral fuel reservoir with a constant flow of 20 mL/min by the pump. A pulse damper provides smooth and continuous flow. Fluid level, pressure and temperature of the sample are continuously monitored while it is pumped through the specified filter into the waste container. Depending on the test, the result is calculated when 300 mL of sample is pumped or the test is aborted when the maximum pressure is exceeded.

FEATURES

  • Unique advantage is the ability to input bias to correlate results from Procedure A to B and vice versa

  • Equipped with graphical touchscreen user interface

  • Real time values for pressure, level, temperature

  • Real time graphical plot of pressure vs volume buildup

  • In-built printer & RS-232 interface

  • Calibration routines for pressure, volume, flow and temperature

  • Custom flow rates

  • RS232 interface

  • Multi-tier password protection - user, service, maintenance & calibration
