Description

Известны компенсационные способы измерени  разности давлений в различных по сечению част х трубопровода разными дифференциальными манометрами. Однако известные способы не обеспечивают высокой точности измерени .Compensatory methods are known for measuring the pressure difference in parts of a pipeline that are different in cross section by different differential pressure gauges. However, the known methods do not provide high measurement accuracy.

В предлагаемом компенсационном способе измерени  разности давлений жидкостными дифференциальными манометрами, с целью повышени  точности измерени , преобразование электрического сигнала в перепад компенсирующего давлени  осуществл етс  электромагнитным жидкостным компенсатором. Принцип действи  такого компенсатора основан на взаимодействии протекающего в электропроводной жидкости электрического тока с магнитным полем посто нного магнита.In the proposed compensation method for measuring the differential pressure by liquid differential pressure gauges, in order to increase the measurement accuracy, the electrical signal is converted into a differential pressure differential by an electromagnetic liquid compensator. The principle of operation of such a compensator is based on the interaction of the electric current flowing in an electrically conductive fluid with a magnetic field of a permanent magnet.

Принцип устройства жидкостного компенсатора заключаетс  в применении б айпасной прозрачной трубки с ртутью- по разности уровней которой определ етс  расход жидкости в трубопроводе. Разность уровней в -трубке фиксируетс  фотоэлектрической схемой, обеспечивающей включение кондукционного насоса дл  создани  компенсирующего давлени . В зависимости от высоты разностного столба кондукционный насос потребл ет различную по величине силу тока дл  поддержани  носто нства уровн  ртути в байпасной трубке. По величине электрического тока определ ют расход жидкости в рабочем трубопроводе. Сигнал разбаланса фотоэлектрической схемы по вл етс  в момент, когда одно из двух фотосопротивлений перекрываетс  столбиком ртути. Баланс схемы наступает, когда перекачиваема  ртуть откроет оба фотосопротивлени .The principle of a liquid compensator device is to use a transparent transparent tube with a mercury - the difference in the levels of which determines the flow rate of the fluid in the pipeline. The difference in the levels in the γ-tube is fixed by a photoelectric circuit, which ensures that the conduction pump is turned on to create a compensating pressure. Depending on the height of the difference column, the conduction pump consumes different magnitudes in order to maintain the level of mercury in the bypass tube. The flow rate in the working pipeline is determined by the magnitude of the electric current. The unbalance signal of the photovoltaic circuit appears at the moment when one of the two photoresistances overlaps with a mercury column. The balance of the scheme occurs when the pumped mercury opens both photoresistances.

На чертеже изображена схема действи  жидкостного компенсатора.The drawing shows a diagram of the action of the liquid compensator.

Фотоэлектрическа  схема содержит в себе осветитель О и два фогосопротивлени  ФС1 и ФС2, включенных в мостовую схему. Сигнал разбаланса, возникающий в диагонали моста, усиливаетс  усилителем УThe photoelectric circuit contains the illuminator O and the two resistances FS1 and FS2 included in the bridge circuit. The unbalance signal that occurs in the diagonal of the bridge is amplified by the amplifier Y
