Abstract
The utility model provides a blowing manometering oil discharge tank observing and controlling instrument, solving the problem of large range liquid measurement in the way of small range measurement and improving the accuracy of air-blowing liquid measurement and calculating at the same time the density of the liquid according to the measured pressure difference. Thus, no electrical articles are taken to the oil tank to cause unsafety; the liquid measurement has high accuracy and is not affected by temperature and the impurity in the oil. The pressure measurement device is free from maintenance; the realization of computerization and modern management is adopted to the modern management system of changeable liquid levels and high measurement requirements.
Description
The utility model relates to level gauging, and it is the important component part of oil depot modern management aspect
The air blowing type level gauging at first is that security is good, and it can not have potential safety hazard to any charged device oil tank of packing into; Next be pack the oil tank parts into can be non-maintaining.But air blowing type level gauging precision is not high, because nearly tens meters of the liquid level of large oil tank has tens millimeters error when system accuracy reaches per mille, the error of several tons of oil is arranged just.To consider that also oil tank lays temperature variation, well cuts composition, the difficulty that waits disturbing factor to bring for accurate measurement in the open.
The purpose of this utility model is in order to improve the precision of air blowing type level gauging greatly, eliminates temperature variation and causes liquid density variation, well cuts composition to cause the fluid density skewness and the error that produces.The data that the utilization computer measurement and control system is realized oil tank reserves automatic measuring and controlling and the library management of oil depot network data input and design automatically---blowing manometering oil drain drum measurement and control instrument.
The utility model is to constitute like this, it connects to form pressure measurement row side by side by hollow tubular, the wherein the longest hollow tubular reaches the bottom of oil tank from the oil tank top, cover the gamut of liquid level change, the length of all the other hollow tubulars is stretched to the bottom in the equal difference mode from the oil tank top, because the length difference of hollow tubular is known, pressure reduction according to the differential pressure pick-up measurement, just can calculate the fluid density value between this two hollow tubulars outlet, being converted among a small circle with regard to level gauging problem on a large scale like this, the level gauging problem solves.
Below in conjunction with accompanying drawing and enforcement the utility model is described in further details.
Accompanying drawing 1 is the utility model structural representation.
With reference to accompanying drawing, the utility model connects to form pressure measurement row (2) side by side by hollow tubular (1), the wherein the longest hollow tubular reaches the bottom of oil tank from the oil tank top, cover the gamut of liquid level change, and the length of all the other hollow tubulars is stretched to the bottom in the equal difference mode from the oil tank top.The length value of equal difference has determined measuring accuracy; The overall height of liquid level change has determined the number of pressure measurement row (2) lining hollow tubular (1).Hollow tubular (1) communicates with solenoid valve (5) by pipeline (4), and solenoid valve (5) communicates with a differential pressure pick-up (6), and solenoid valve (5) links to each other with compressed air source (8) by flow controller (7).Because the length difference of two hollow tubulars being connected simultaneously by solenoid valve (5) is known,, just can calculate the fluid density value of these two hollow tubulars between exporting according to the pressure reduction that differential pressure pick-up (6) is measured.These hollow tubulars (1) are connected in circulation in twos, just can measure the fluid density value and the distribution thereof that are switched between the hollow tubular outlet, also can determine the pipe numbering of outlet from the nearest hollow tubular of liquid level (3) simultaneously, have just determined the round values of liquid level.Differential pressure pick-up (6) also can be measured liquid level (3) to the pressure values between the down nearest hollow tubular outlet of liquid level (3), just can calculate the fraction part of liquid level in conjunction with the density value that calculates, add that the integral part of liquid level just can be calculated liquid level numerical value comparatively accurately.Above-mentioned measurement, calculating, control are served as by computer measurement and control system (9), and computer measurement and control system (9) links to each other with differential pressure pickup (6), solenoid valve (5), flow controller (7) simultaneously.
The utility model can not have potential safety hazard to any charged device oil tank of packing into; Level gauging precision height is not subjected to temperature variation, well cuts composition influence; The pressure measurement row of oil tank of packing into is non-maintaining device; The realization of computer measurement and control and network data library management, will be applied to easily as the oil depot liquid level change big, in the demanding modern management system of measuring accuracy.
