Work process：
It is not added with the automatic gauge of outer power：Crude oil (fluid) is risen to well head by oil pumper from oil well, enters oil pumper
Special gas, oil, water three-phase flow rate meter import, wash check valve 1 valve open, enter pipe 14, reach double three from entering pipe 14
Port valve 2, operates valve port by electric magnet 6,7, is assigned to A mouth or B mouth, and then the C mouth of arrival volumetric flowmeter 3 or D mouth, false
If opening B mouth, crude oil (fluid) promotes piston 4 to move to C mouth direction from D mouth, when piston 4 reaches C mouth, current vortex sensor
10 sense signal, transmit a signal to controller 5, and controller 5 is not eager to send control instruction, continues to put into the pulse of determination
The oil flow Δ of equivalenttCome in, pressure will be measured by pressure transducer 12 before and after coming in, be worth for p1And p2, then control
Device 5 sends electromagnet action control instruction, makes electric magnet 6 action, closes B mouth, connects A mouth, and crude oil (fluid) goes successively to, and lives
Plug 4 moves to D mouth direction from C mouth, when reaching D mouth, current vortex sensor 11, and sense signal, pass the signal to controller
5, controller 5 records volumetric values, is not eager to send control instruction, continues to put into the oil flow of the pulse equivalency of determination
ΔtCome in, pressure will be measured by pressure transducer 12 before and after coming in, be worth for p1And p2, then send electromagnet action and refer to
Order, electric magnet 7 action, close A mouth, open B mouth, piston 4 moves to C mouth direction from D mouth, when reaching C mouth, current vortex sensor
10 sense signal, transmit a signal to controller 5, and volumetric values plus one by controller 5, and make electric magnet 6 action, open A mouth,
Close B mouth, above action reciprocation cycle, thus reaching the automatic gauge work of unpowered volumetric flowmeter.
Volumetric flowmeter measures, and how gas-liquid knows the content of gas and the content of liquid, that is, gas,
Liquid proportional？That is necessary for allowing volumetric flowmeter itself possess such function.
Computational methods：
T is total=total effective volume flow
D=oil cylinder internal diameter
L=piston effective exercise distance, i.e. length of oil cylinder
The single stroke of volumetric flowmeter, has filled with the mixing liquid of a volume in volume, that is, runs in piston 4
During to D mouth end, controller 5 is not eager to send out the instruction controlling electric magnet 7, at this moment allows the interior continuation of container inject crude oil (fluid), but
It is only to arrive commutation (operation electric magnet) from now on, record check valve opening time, organic unit interval, e.g., one
Millisecond is a unit interval or a pulse.To calculate before this, the check valve of the full volume of crude oil (fluid) opens the door
Umber of pulse, the corresponding number of fluids of each pulse, that is, flow, for example, the total capacity of volume is 100 milliliters, check valve
100 pulses of opening time, each pulsion phase is when one milliliter of fluid, here it is the flow value of check valve.Also to survey simultaneously
In the volume that amount crude oil (fluid) is just reached during volume pressure and start to operate during electric magnet volume in pressure, according to the above time
The measurement data of point, just can calculate air-liquid ratio value, computational methods：Cumulative volume (participation volume)=gas volume+liquid volume
Cumulative volume is datum, and liquid volume is unknown number, and gas volume is unknown number.
When liquid volume increases a determination amount, the gas volume space shared by gas in other words, just decrease a liquid
Body volume increase is really quantitative.But, gas pressure increased one and can measure determination amount.Assume that liquid determines that incrementss are injected
Afterwards, pressure increased one times, and the space shared by gas just reduces one times.Sky before liquid determines incrementss injection, shared by gas
Between be that 2 times of liquid determines incrementss, after liquid determines incrementss injection, the space shared by gas is that liquid determines incrementss.
(according to Mohr's theorem)
(can be with survey calculation)
T is total=T gas+T liquid
p2=liquid determines pressure after incrementss injection
p1=liquid determines pressure before incrementss injection
Δt=liquid determines incrementss
T gas=volumetric flow of gas
T liquid=liquid volume flow
T is total=total effective volume flow
How to allow volumetric flowmeter be air-liquid proportional sensor simultaneously again？So complete：In piston one
In one way, calculate the opening time of check valve on throttling element, the umber of pulse of certain time.Calculate, each pulse
Corresponding flow value.Remember, when piston reaches that endvertex equipped with pressure transducer, do not rush to commutate, measure this
When pressure, p1Place on record, then put several or tens pulses fluids again and come in, ΔtPlace on record.According toCalculate volume shared by gas, certain liquid volume is also known that, air-liquid ratio it is also known that.Arrive
This, the biphase unit of air-liquid has completed.Must not forget to commutate.
Then, oil-water ratio sensor is started working.
Cooperation oil-water ratio sensor, can measure and obtain oil-water ratio value, total liquid measure × water ratio (percent)=water
Yield, total liquid measure × oil ratio (percent)=oil yield.Arrive this, gas, oil, the metering of water three-phase flow rate meter terminate.
Calculated examples：
1, cumulative volume, for example：Volumetric flowmeter, cylinder diameter D=10cm, the long L=30cm of cylinder body,
Cumulative volume=2356cm after substitution3.
2, gas volume, for example：After the full cylinder of gas liquid mixture, record pressure p1=0.1mp, adds Δt=100cm3, survey
Obtain pressure p2=0.2mp,Gas volume=100cm after substitution3.
3, liquid volume：It is liquid volume that cumulative volume deducts gas volume, 2356cm3-100cm3=2256cm3.
Oil body volume：For example, profit rate value, oil 30 percent, water oil 70 percent are recorded.
Oil body volume=2256cm3× 0.3=676.8cm3.
4, water body volume：Water body volume=2256cm3× 0.7=1579.2cm3.
