MICRO-SEPAROMETER MARK V DELUXE OPERATION MANUAL 1.0 SCOPE 1.1 The Micro-Separometer Mark V Deluxe incorporates solid state design and self-contained power source. The instrument provides a quick, portable means for field and laboratory use to rate the ability of aviation turbine fuels to release entrained or emulsified water when passed through fiberglass coalescence material. 2.0 SIGNIFICANCE 2.1 The test provides a measure of surface active materials in aviation turbine fuels. These are known to affect the ability of filter separators to separate free water from fuel. 3.0 DEFINITION 3.1 To distinguish from the standard Water Separometer rating (WSIM) and Minisonic Separometer rating WSIM (MSS), the Micro-Separometer numerical rating should be reported as Micro-Separometer rating (MSEP). 4.0 SUMMARY OF METHOD 4.1 The fuel sample is emulsified with water in a syringe, using the emulsifier which is programmed to operate for a predetermined time period. After emulsification there is a programmed waiting period to allow time to insert the plunger, add the ALUMICEL® COALESCER and place the entire assembly on the syringe drive. The sample is expelled from the syringe at a programmed rate by the syringe drive mechanism through a standard ALUMICEL® COALESCER. When all of the fuel has been expelled from the syringe, another programmed waiting period is initiated to allow the coalesced water to settle. At the end of the settling time period, an audible signal sounds. Immediately after the audible signal stops, the meter indicates the Micro-Separometer rating which is a measure of the uncoalesced water remaining in the fuel. The results are reported on a 0-100 scale to the nearest whole number. High ratings indicate the water is easily coalesced, and the fuel is relatively free of surfactant materials. A test can be performed in approximately 5 minutes. 5.0 APPARATUS 5.1 The Micro-Separometer is a completely portable and self-contained unit, operating on an internal rechargeable battery. The unit may be operated at sites where no AC power COPYRIGHT 1984 EMCEE ELECTRONICS, INC. REVISION DATE: FEBRUARY 12, 1987 PAGE 3
