Abstract
The utility model relates to a radar telemetering direct-reading liquid level alarm device which comprises a slurry tank (1), wherein a frequency-modulation radar level meter (2) is arranged on the upper end face of the slurry tank (1) and connected with a liquid level digital indicator (3) through a signal wire, the liquid level digital indicator (3) is provided with a high level limit alarm display (4) and a low level limit alarm display (5). The radar telemetering direct-reading liquid level alarm device can monitor the liquid levels of slurry at any time and realize automatic alarm prompting in a certain scope of slurry liquid levels.
Description
Technical field:
The utility model relates to the used a kind of liquid level emasuring device in field, oil field, particularly a kind of radar remote transmitting direct reading formula liquid level warning device.
Background technology:
The slurry tank that existing wellbore construction is used is not all installed liquid level indication and warning device, when the post employee on the oil field observes liquid level, have only to the peep hole of abhiseca and observe, very inconvenience and error are bigger, if observe untimely, will be to produce producing certain influence.In order to address this problem, engineers and technicians also once attempted installing and measuring mud liquid level instrument in tank body.But these existing liquid level interface instrument prices are expensive and measure not precisely, and when using at the scene, limitation is very big, and the cost that causes finishing the work of slurry tank level gauging is higher, is difficult to promote in practice.
The utility model content:
In order to solve the problem in the background technology, the utility model provides a kind of radar remote transmitting direct reading formula liquid level warning device, and this device can be monitored mud level at any time, and realizes automatic alarm device in certain mud level scope.
The technical solution of the utility model is: this radar remote transmitting direct reading formula liquid level warning device comprises slurry tank, the upper surface of slurry tank is equipped with the frequency modulation radar body place meter, the frequency modulation radar body place meter is connected with the liquid level digital indicator by holding wire, and high liquid level limit alarm indication and the alarm indication of low liquid level limit are arranged on the liquid level digital indicator.
Above-mentioned slurry tank is fixed with a steel drum, on the steel drum wall water hole is arranged, and the part of frequency modulation radar body place meter in slurry tank is positioned at steel drum.
The utlity model has following beneficial effect: the level gauging that frequency modulation radar body place meter and height displaying instrument table is applied to slurry tank at this programme, the frequency modulation radar body place meter has following advantage in the use: 1., measure continuously accurately, radar levelmeter does not contact with measured medium, and be not subjected to temperature, pressure, gas, noise, water vapour etc. influences; 2., easy to maintenance, simple to operate; 1., grating shows, experience for the people intuitively the height displaying instrument table has the Displaying Meter of following function:; 2., numeral shows, shows current level value accurately; 3., alarm, the influence of having avoided noisy site environment to cause by optical flare.When drilling crew works in drilling well, monitor mud level at any time, surpass the certain working range warning of current liquid level.This novel monitoring mud level of not only giving brings convenience, measures accurately, and more each drilling crew can provide timely and accurate data to the mudman in drilling well.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
1-slurry tank among the figure, 2-frequency modulation radar body place meter, 3-liquid level digital indicator, the alarm indication of the high liquid level limit of 4-, the alarm indication of the low liquid level limit of 5-, 6-steel drum, 7-water hole.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing: as shown in the drawing, this radar liquid level warning device comprises slurry tank 1, the upper surface of slurry tank 1 is equipped with frequency modulation radar body place meter 2, frequency modulation radar body place meter 2 is connected with liquid level digital indicator 3 by holding wire, and high liquid level limit alarm indication 4 and the alarm indication 5. of low liquid level limit are arranged on the liquid level digital indicator 3
EDTP-MRC type liquid level radar adopts FMCW (frequency modulation(PFM)/continuous wave) system, can reach the certainty of measurement of metering level.Through warbled electromagnetic wave signal, the signal that measured surface returns is launched antenna and receives the radar levelmeter 2 that is installed in tank deck by day alignment liquid level emission, and with the instantaneous frequency signal of antenna emission relatively.Because the frequency of signal constantly changes according to certain rule, so comparison signal frequency and antenna are proportional to the air line distance of liquid level.Composite measurement signal and oil tank form parameter are carried out geometric manipulations, just can obtain accurate liquid level and surplus information.Show and report to the police by liquid level digital indicator 3.
There is stirring motor the slurry tank inside that has, liquid level ripple 1-2cm.For fear of the interference that ripple causes, obtain liquid level data more accurately, in the mud tank body, added a steel drum 6 (iron or stainless steel make) in the installation process, make the fluctuation of mud in metal bucket (about 5mm) in allowed limits.On steel drum 6 walls water hole 7 is arranged, the part of radar levelmeter (2) in slurry tank (1) is positioned at steel drum 6.Liquid in the slurry tank 1 can be entered in the steel drum 6 by water hole 7, keeps liquid level and the slurry tank 1 interior liquid level in the steel drum 6 to equate.
