an apparatus for separating and measuring mixed fluids , directed especially towards the separation of crude oil and water and the volumetric measurement of each of the primary constituent fluids , shown in fig1 - 4 of the drawings , the apparatus 10 comprising essentially a vertically oriented cylindrical vessel 20 positioned on a support frame 15 , the vessel 20 having an interior 21 , an exterior surface 23 , an upper outlet 26 located in a top portion 25 of the vessel 20 , a lower outlet 28 located in a bottom portion 27 of the vessel 20 and an inlet 29 located approximately half way between the top portion 25 and bottom portion 27 from the exterior surface 23 into the interior 21 of the vessel 20 , an adjustably buoyant vertical float member 30 positioned within the interior 21 of the vessel 20 , the float member 30 having an upper end 32 and a lower end 36 , an upper housing 50 attached to the upper outlet 26 , a lower housing 60 attached to the lower outlet 28 , each of the upper housing 50 and lower housing 60 having a tapered interior seat 52 , 62 adapted to sealably engage rounded ball seals 34 , 38 on the respective upper end 32 and lower end 36 of the float member 30 , an external surge tank 40 connecting to the inlet 29 , the external surge tank 40 further connected to the outlet of an oil well or fluid source , not shown nor claimed as part of the apparatus , a first pipeline 70 connecting to the upper housing 50 having a fluid flow measuring first meter 76 measuring the fluid flowing from the upper outlet 26 of the vessel 20 , a second pipeline 72 connecting to the lower housing 60 having a fluid flow measuring second meter 78 measuring the fluid flowing from the lower outlet 28 of the vessel 20 , and a third pipeline 74 beyond the first and second meters 76 , 78 carrying the fluids to a remote storage tank or to a return line , also not claimed or shown as part of the apparatus . the float member 30 , shown in fig3 of the drawings , has a hollow interior 35 which may be filled with a neutral liquid ballast 100 to adjust the buoyancy of the float member 30 , the float member having the upper end separable from the float member allowing access to the hollow interior 35 . the apparatus 10 may further comprise a float housing 80 , shown only in fig1 of the drawings , located within the interior 21 of the vessel 20 , connecting the upper outlet 26 with the lower outlet 28 with the float member 30 contained within the float housing 80 . the float member 30 has full and free movement within the float housing 80 without any substantial contact with the float housing 80 . this float housing 80 has a plurality of grooved channels 82 allowing for the free flow of fluid in and out of the float housing 80 , from the interior 21 of the vessel 20 to the float member 30 without restriction . the surge tank 40 , shown in fig3 and 4 of the drawings , further includes an inlet line connection 42 , an internal chamber 44 and an outlet connection 46 , attaching to the inlet 29 of the vessel 20 . it is most preferred that the inlet line 42 is positioned lower on the surge tank 40 than the outlet connection 46 , as experimentation has revealed that this orientation reduces the amount of fluid churn within the internal chamber 44 and produces a smoother flow of fluid from the internal chamber 44 thorough the outlet connection 46 to the inlet 29 of the vessel 20 . in the event the apparatus 10 is used where a steady flow of fluid enters the vessel 20 , without pulsation , the surge tank 40 may be omitted and the vessel 20 connecting directly to the fluid source at the inlet 29 . when assembled , a fluid mixture 200 is first introduced into the surge tank 80 where the fluid mixture 200 is allowed to collect , whereafter the fluid mixture 200 is transferred to the inlet 29 of the vessel 20 . the fluid mixture 200 is then collected within the interior 21 of the vessel 20 , where it separates into its fluid components of differing specific gravities , primarily crude oil as a lighter fluid 210 , rising to the top portion 25 of the vessel 20 , with a heavier fluid 220 , primarily water , separating to the bottom portion 27 of the vessel 20 . the float member 30 , having the hollow interior 35 containing the neutral liquid ballast 100 , preferably antifreeze liquid , is adjusted to float at a preferred adjusted level within the vessel 20 , dependant upon a level of separation of the fluid mixture 200 within the vessel 20 . when a quantity of heavier fluid 220 is reached in the tank , the float member 30 rises above the preferred adjusted level , urging the ball seal 38 on the lower end 36 of the float member 30 away from the tapered interior seat 62 of the lower housing 60 , expelling the heavier fluid 220 from the lower outlet 28 into the second pipeline 72 where it is measured by the second meter 78 . as that heavier fluid 220 is released , the float member 30 is lowered dropping the ball seal 34 on the upper end 32 of the float member 30 away from the tapered interior seat 52 of the upper housing 50 , releasing the lighter fluid 210 , or crude oil , through the upper outlet 26 into the first pipeline 70 where it is measured by the first meter 76 . cutoff valves 75 may be supplied on any of the first , second or third pipelines 72 , 74 , 76 , or at the inlet line 42 to the surge tank 40 . in an alternative embodiment , shown in fig4 of the drawings , an externally controlled buoyancy adjustment mechanism 90 is provided on the apparatus 10 , allowing for the float member 30 to have its buoyancy adjusted without the need to disassemble the apparatus 10 or to manually fill the hollow interior 35 of the float member 30 with the neutral liquid ballast 100 . the externally controlled buoyancy adjustment mechanism 90 comprising a fluid pump 92 having a fluid injection and extraction means 94 operated by a control lever 95 , a fluid inlet line 96 connecting the fluid injection and extraction means 94 to the hollow interior 35 of the float member 30 , and a fluid outlet line 98 connecting the hollow interior 35 at the lower end 36 of the float member 30 to the fluid injection and extraction means 94 . this externally controlled buoyancy adjustment mechanism 90 thus operates to allow the introduction and extraction of the neutral liquid ballast 100 into the float member 30 by a pull or push of the control lever 95 , adding or subtracting the neutral liquid ballast 100 from the hollow interior 35 of the float member 30 without disassembly of the apparatus 10 . this embodiment may also provide the float member 30 with an air relief line 37 attached near the upper end 32 of the float member 30 , the air relief line 37 further connecting to an air valve 39 located on the exterior surface 23 of the vessel 20 , as shown in fig4 of the drawings . this air valve 39 allows for the neutral liquid ballast 100 in the hollow interior 35 of the float member 30 to rise and fall with the addition or extraction of neutral liquid ballast 100 without concern over pressure or vacuum in the float member 30 . the ball seal 34 on the upper end 32 of the float member 30 is conformed to sealably engage the tapered interior seat 52 of the upper housing 50 , while the ball seal 38 on the lower end 36 of the float member 30 is conformed to sealably engage the tapered interior seat 62 of the lower housing 60 . the float member 30 is of a length to be contained between the upper housing 50 and the lower housing 60 when the housings are attached to the vessel 20 , but the ball seals 34 , 38 on the upper end 32 and lower end 36 of the float member 30 are not engaged with the tapered interior seats 52 , 62 of the upper housing 50 and lower housing 60 at the same time . this allows for either flow of the lighter fluid 210 from the upper outlet 26 , heavier fluid 220 flow from the lower outlet 28 or both lighter fluid 210 and heavier fluid flow 220 from both the upper outlet 26 and lower outlet 28 simultaneously , but never restricting the fluid flow from both the upper outlet 26 and lower outlet 28 at the same time . as the fluid passes through the respective first meter 76 and second meter 78 , the quantity of fluids passing through the meters is recorded . in an alternative embodiment , these meters 76 , 78 may be equipped with a remote interface means to allow the recorded volume of liquid passing through the meters to be wirelessly transmitted to a remote location , thereby avoiding the necessity to travel to a variety of locations to read the measurements recorded by the meters . this would be especially beneficial when numerous apparatus 10 are attached to numerous oil wells in distant locations . it is contemplated within the scope of this invention that the geometric shape of the elements involved in the invention are of no functional distinction , although correlated to be suitable for the stated purpose of the invention . therefore , the shape of the float member 30 and the vessel 20 may be hexagonal , square , cylindrical , as claimed and disclosed , triangular , oval , round or whatever shape may optimize the separation process . likewise , the shape of the ball seals 34 , 38 and the tapered interior seat 52 , 62 must be consistent insofar as forming a seal , but their respective shapes may be flat , conical or wedge - shaped , or the valve seats and seals may form a sliding gate assembly . additionally , the sealable engagement between the ball seals 34 , 38 and the tapered interior seats 52 , 62 may be of varying porosities to inhibit or accentuate the pressure according to the requirements , pressure , or viscosity of the fluids be measured or separated . the apparatus 10 may be furnished as a portable unit which would avoid having to disassemble the apparatus 10 when moving from one fluid source to another , enhancing transferability from one oil well to another , or it may be made a permanent part of the oil well . in the embodiments depicted in fig2 - 4 , the vessel 20 is supported above the ground on the support frame 15 . it is also contemplated that the apparatus 10 may be mounted on a cart , trailer or wagon , and may include a protective cover , not shown . the apparatus 10 has advantages and addresses the issues presented by prior art and processes . the apparatus 10 and process requires nothing more than kinetic energy produced by the fluid flow for the basic apparatus 10 to operate . the fluid is under constant pressure and motion as it travels through the apparatus 10 , thereby reducing the possibility of the fluid or contaminants clogging or forming solid deposits within the vessel 20 , the surge tank or any of the pipelines , meters , inlets or outlets . fluid is measured without draining or opening the lines . with the float member 30 suspended within the fluid and in constant motion so long as a fluid flow is maintained in the apparatus 10 and the ball seals 34 , 38 on the upper end 32 and lower end 36 attaching in tandem on the float member 30 , the constant motion prevents the ball seals 34 , 38 from becoming stuck within the tapered interior seats 52 , 62 . short of a cataclysmic failure or damage to the entire float member 30 , the apparatus 10 cannot experience failure in a tapered interior seat 52 , 62 or ball seals 34 , 38 from opening or closing as the fluid volumes are constantly changed . additionally , because the float member 30 would be biased towards keeping the upper outlet 26 and lower outlet 28 opened , due to the float member 30 adjusted to be suspended between the upper and lower outlets 26 , 28 , the fluid measurement is ongoing , thereby eliminating the need to guess , estimate of statistically deduce the fluid flow from the well , the meters conducting actual measurement of the fluid flow at a given moment , or a short or long period of time . the apparatus 10 is also capable of separating other mixed fluids which may separate due to distinctly differing specific gravities or may be applied to environmental cleanup activity . in this use , it may be desirable to leave the fluid separated and not connect the first and second pipelines 70 , 72 back together past the first and second meters 76 , 78 , porting the fluids to separate storage tanks or vessels . additionally , in oil spills , it may be desirable to gather water at the spill site using a skimming technique and using the apparatus to separate the petroleum product from the seawater and return the seawater to the sea . also , use of the first and second meters 76 , 78 , singularly or both , may be deleted during this type use . while the invention has been particularly shown and described with reference to a preferred embodiment thereof , it will be understood by those skilled in the art that changes in form and detail may be made therein without departing from the spirit and scope of the invention .
