Abstract
The utility model provides a differential pressure measurement liquid level device which comprises a liquid container, a U-shaped measuring pipe, measuring liquid and a water tank, wherein the U-shaped measuring pipe is connected to the liquid container, the measuring liquid is contained in the U-shaped measuring pipe and can produce liquid difference, the water tank is communicated with the U-shaped measuring pipe, and the water tank is communicated with the liquid container. The differential pressure measurement liquid level device is small in measuring error, simple in structure, convenient to operate and wide in application range.
Description
Technical field
The utility model is specifically related to the differential pressure measurement level gauge.
Background technology
The differential pressure measurement liquid level is mainly used in the airtight level gauging that pressure vessel is arranged, measure the liquid level of closed container, because gaseous pressure is influential to the pressure of certain point in the container, the negative pressure chamber of differential pressure transmitter need to be linked to each other with the gas-phase space of container, hydrostatic pressure with the Balance Air phase pressure, the size of differential pressure has represented the size of liquid level equally, measure gas with differential pressure gauge, differential pressure value between the liquid two-phase is learnt height of liquid level, by measuring principle as can be known, the every instrument that can measure differential pressure may be used to the measurement of closed vessel liquid level, in the actual production, using maximum is electronic differential pressure transmitter and capacitance differential pressure cell, no matter static pressure type or differential pressure type level gauging instrument, if Media density changes in application, no matter this variation is because temperature variation or change of component cause, all can produce significant measuring error.
Summary of the invention
Technical problem to be solved in the utility model is to provide the differential pressure measurement level gauge, and test error is little, simple in structure, easy to operate, utilization is more extensive.
For solving above-mentioned existing technical matters, the utility model adopts following scheme: the differential pressure measurement level gauge, comprise liquid container, be connected to U-shaped measuring tube on the liquid container, be contained in can produce in the U-shaped measuring tube the poor measurement liquid of liquid, with the water tank that the U-shaped measuring tube is communicated with, described water tank is communicated with liquid container.
As preferably, be provided with the first solenoid valve between described liquid container and the water tank, the first electromagnetic valve structure between this structured liquids container and the water tank is more reasonable, and handling safety is reliable.
As preferably, be provided with the second solenoid valve between described liquid container and the U-shaped measuring tube, the further strengthen operation security and stability of the second solenoid valve between this structured liquids container and the U-shaped measuring tube, structure is more reasonable, and is easy to operate.
Beneficial effect:
The utility model adopts technique scheme that the differential pressure measurement level gauge is provided, and test error is little, simple in structure, easy to operate, utilization is more extensive.
Description of drawings
Fig. 1 is structural perspective of the present utility model.
Embodiment
As shown in Figure 1, the differential pressure measurement level gauge, comprise liquid container 1, be connected to U-shaped measuring tube 2 on the liquid container 1, be contained in the water tanks 4 that can produce the poor measurement liquid 3 of liquid, be communicated with U-shaped measuring tube 2 in the U-shaped measuring tube 2, described water tank 4 is communicated with liquid container 1, be provided with the first solenoid valve 5 between described liquid container 1 and the water tank 4, be provided with the second solenoid valve 6 between described liquid container 1 and the U-shaped measuring tube 2.
