Mostly in the gauge line of single function, and its pipe, space is little, can only measure a small amount of liquid；Part metering device is not set in water side
There is U-tube device balance pressure, after gauge line upper end connection atmospheric pressure, its liquid in pipe all can flow under gravity
Go out, there is irrationality in design；
(2) density contrast in gauge line between the pressure difference value and medium of liquid level is recorded calculating by differential pressure pick-up
Oil, the variable quantity of gas and water, such metering device defect are to calculate complicated, and need measurement profit density and pressure in advance
Force value, indirectly measurement increased the cumulative error of experiment；
(3) by the combination of the complex devices such as level sensor, pressure transducer, computer and various pumps calculating oil
Air water level change or change of production, such metering device complex structure, involve great expense.
The content of the invention

Put, using oil gas water three phase liquid gravity difference, by the opening and closing of J-type pipe (2) oil-out (8) and air vent (7), can
The separate measurement of oil gas water arbitrarily biphase or three-phase is realized, while can also select to open to oil-out according to the cumulative oil production estimated
Open or close, realize that double-range is measured, can be used for water drive experiment and can also be used for saturated oils experiment.This utility model simple structure,
Low cost, easy to operate, metering intuitively accurately and can realize the advantages of multi-functional, double-range is measured.
This utility model is a kind of oil gas water three phase separate measurement device, by leveling base (1), J-type pipe (2), gas stream
Gauge (3) is constituted.On the left of described J-type pipe (2), pipe is provided with outlet (4), and bottom is provided with waste liquid leakage fluid dram (5)；Described J-type
Inlet (6) is provided with the top of pipe on the right side of pipe (2), right side tube side is provided with air vent (7), oil-out (8), mixed liquor from top to bottom and enters
Liquid mouth (9)；Described leveling base (1) is made up of leveling serew (10) and base；Described air vent (7) connection gas flow
Meter (3)；Described J-type pipe (2) is fixed on leveling base (1).On the right side of J-type pipe (2), inside pipe wall is carved with positive and negative centre zero scale, its
On the left of 0 scale datum line and described J-type pipe (2), the outlet (4) of pipe is in same level height.On the right side of J-type pipe (2), pipe goes out
Hydraulic fluid port (8) is slightly above 0 scale datum line.
