Further, described measuring box is the arrangement of upper and lower vertical configuration spacing.
Further, described measuring box is fixed on the same face of a support, and this frame bottom is provided with counterweight.
Further, the top end face of described measuring box is provided with pressure transducer.
Further, described temperature control heating device is heating tape.
Further, described pressure transducer gathers transtation mission circuit by pressure signal and is connected with corresponding data handling system.
Further, described pressure signal collection transtation mission circuit is arranged on an independent collection transmission box box being positioned at oil tank outside.
Further, the setting height(from bottom) site error 0.1% of described pressure transducer, measuring accuracy reaches 0.1%.
Owing to adopting technical scheme as above, the utility model has following beneficial effect:
Device for measuring crude oil parameter in oil tank described in the utility model not only structure is simple, convenient operation, and use safety, is easy to safeguard; Described device gathers related data parameter by the pressure transducer of upper and lower calibrated altitude difference, thus the density of crude oil in oil tank can be calculated in time, and then the ratio of oil and water in crude oil is conversed by oil density, finally reach the object calculating oil density, output and water percentage promptly and accurately; In addition, described device can also install corresponding temperature control heating device in measuring box, thus reaches and effectively to avoid when cold snap the crude oil Yin Wendu in oil tank to reduce causing mobility to be deteriorated the object of the pressure measurement errors brought.
[accompanying drawing explanation]
Fig. 1 is schematic diagram of the present utility model;
Fig. 2 is another structural representation of the present utility model.
In figure: 1, measuring box; 2, pressure transducer; 3, conduit; 4, support; 5, counterweight; 6, transmission box is gathered.
[embodiment]
Can explain the present invention in more detail by the following examples, open the purpose of this utility model is intended to protect all changes and improvements within the scope of the utility model, and the utility model is not limited to the following examples:
The device for measuring crude oil parameter in oil tank by reference to the accompanying drawings described in 1 ~ 2, described device comprises at least two airtight measuring boxes 1 and pressure transducer 2, namely the quantity of measuring box 1 and pressure transducer 2 can be set according to the size of oil tank or actual needs, changed by the pressure of Timing measurement pressure transducer, crude oil can be obtained in conjunction with storage tank cross-sectional area and enter tank speed, namely crude production rate, simultaneously, accurately can be converted by multi-segment calibrated altitude pressure reduction measured between multiple measuring box 1 density of crude oil, and then converse the water percentage of crude oil, the present embodiment is to arrange two measuring boxes 1, and these two measuring box 1 correspondences are in upper and lower spacing shape arrangement, and the distance namely between two measuring boxes 1 is certain, and are set to corresponding arrangement up and down, described device is implemented for ease of installing, these two measuring boxes 1 can be set to vertical configuration, and by being provided with counterweight 5 bottom one, support 4 in vertical shape fixes two measuring boxes 1, thus carry out effective guarantee two measuring boxes 1 by support 4 and can be in state vertical up and down all the time in oil tank, and then ensure that measurement data accurately and stability, for being calculated the density of crude oil by upper and lower calibrated altitude difference, the top end face of each measuring box 1 is provided with one for measuring the pressure transducer 2 of crude oil pressure in oil tank, thus the density of measuring and calculating crude oil promptly and accurately can be carried out by the pressure data measured by these two the opposing parallel pressure transducers 2 in crude oil liquid level, then go out the output of oil pumper in conjunction with oil tank sectional area Accurate Determining, and accurately to be converted water percentage by the density of crude oil, as required, the setting height(from bottom) site error of two pressure transducers 2 can be set to 0.1%, thus make the measuring accuracy of pressure transducer reach 0.1%, make density measure error reach 0.2%,
For adapting to the weather of northern China cold season, corresponding temperature control heating device can be set in the box of measuring box 1, such as twine in measuring box 1 box and establish heating tape, thus utilize temperature control heating device to have influence on the accuracy of measurement because of mobility variation to avoid the crude oil in oil tank in cold snap; In addition, by pressure transducer 2 and ambient atmosphere UNICOM can be kept, and can intert pressure transducer circuit and with the insulated conduit 3 of temperature control heating device circuit, two measuring boxes 1 are communicated with, namely this conduit 3 not only effectively can ensure that the air pressure in measuring box 1 box and the atmospheric pressure outside oil tank are consistent, but also the line related safety of pressure transducer 2 and temperature control heating device can be caused oil tank outside by airtight measuring box 1 box, thus ensure the normal work of pressure transducer 2 and temperature control heating device; As required, independently can gather in oil tank outer setting one and send box 6, this collection sends in box 6 box and is provided with pressure signal collection transtation mission circuit, described pressure transducer 2 gathers transtation mission circuit be connected with corresponding data handling system by gathering the pressure signal sent in box 6 box, thus reaches and utilize corresponding data handling system to gather timely and the object of the corresponding data that converts.
