The problem in running the MiniMonitor® (a.k.a. “Millipore” TM Millipore Corp.) membrane test for particulate/dirt detection in Jet Fuel is the bucket. Many years ago, the ASTM reduced the problem by changing the sample volume from 3 gallons to just 1, but the hassle of having to deal with buckets of fuel remained – UNTIL NOW.

The Closed Loop MiniMonitor® eliminates the bucket. It reduces spills, waste and personnel exposure by keeping the fuel completely inside the fuel system itself. All the test fuel is recoverable. On a hydrant cart, it can be directed to a recovery tank and on a truck or in a fuel tank system, it can be directed back to storage.

Trays and testers sold separately, mount one tray on each truck and at the fuel farm, buy just one (or two if needed) Closed Loop MiniMonitor®.

Simply put the Plastic Monitor into the Closed Loop MiniMonitor® and then:

  • 1

    Turn the inlet selector valve (optional) to “Filter Inlet” or Filter Outlet”

  • 2

    Turn the control valve to “Flush” and watch the CLMM fuel meter to flush the connection.

  • 3

    Turn the control valve to “Test” and allow 1 gallon to pass through the Membrane in the Plastic Monitor.

  • 4

    Turn the valve to “Off”. (MUST be in the off position before removing cap).

  • 5

    Remove the plastic monitor and evaluate the results.

In addition to the obvious savings over disposing of test fuel and preventing spills, this approach allows you to run tests so quickly and easily that the results have much more meaning that tests run minutes or even hours apart, in which you have to handle buckets of fuel.
