Model 1140 - Micro Separometer- Brochure

EMCEE Model 1140 MICRO-SEPAROMETER™Emcee Electronics, Inc.520 Cypress Avenue * Venice, Florida 34285(ASTM Standard Test Methods D3948, D7224, D7261 & D4860)For quality control purposes, water separation characteristics of fuels are rated to determine the amount ofsurface active materials (surfactants) present. Surfactants degrade the performance of filter separatorsused to remove water from the fuel. The presence of water can impair engine performance and initiatemicrobiological growth, which can cause corrosion in tanks and filter plugging in fuel lines. Also forquality control purposes, fuels are subjected to “Clear & Bright” tests to determine the amount of freewater and particulate matter in mid-distillates.The Model 1140 Micro-Separometer is aelectro-mechanical instrument used to perform four discrete tests.ASTM Standard Test Methods D3948 (Jet), D7224 (Jet) andD7261 (Diesel) are used to rate water separation characteristicsand D4860 (Jet or Diesel) detects and numerically rates freewater and particulate contamination. Note - This instrumentperforms each of the four tests above simply by using one of thefour “Six Packs” containing the proper coalescer cells.™ instrumentPhone: (941) 485-1515 * Fax: (941) 488-4648 * E-Mail: emcee-sales@verizon.netWater Separation CharacteristicDescription of Instrument & TestsModel 1140 Micro-Separometer™Water Separation Instrument“Six Pack” Test ExpendablesIncluding Coalescer CellsWATER SEPARATION CHARACTERISTIC, FREE WATER AND PARTICULATE TESTINGTest Method D3948, D7224 and D7261 employs the use of aturbidimeter, a mechanical mixer, and a disposable coalescer filter.A portion of the sample, in a clear glass vial, is used to set the meterto read 100. The sample in the vial is discarded and the vial isretained.Another portion of the sample in a plastic syringe is used to createa water/fuel emulsion using the mixer. The emulsion is passedthrough the filter at a programmed rate and a portion is collectedin the retained vial. The vial is replaced in the turbidimeter andthe water separation characteristic of the fuel is rated.The value obtained is compared to the unprocessed sample thatwas used to set the meter to 100. The higher the rating, 100 beingthe maximum, the less surfactant present.Free Water and Particulate Contamination(Clear & Bright)Test Method D 4860 passes a portion of the sample through afilter medium, which is collected in a clear glass, vial. The vial isplaced in the turbidimeter and the meter is adjusted to 100. Theprocessed fuel is discarded and a portion of the unprocessed fuel isplaced in the vial, which is re-inserted in the turbidimeter. Higherratings, 100 is maximum, indicate that there is less free water andparticulate present.A box commonly known as a “SixPack” that contains six test kits isshown above. Each Test Kit containsvacuum packed expendables that areused to perform a single test. Eachcoalescer/filter is labeled to identify thetype of fuel and the applicable ASTMmethod to be used. A container ofdistilled water is also included in eachSix Pack to perform water separationtests.
