Abstract
The utility model relates to a disk display high-precision liquid level meter which belongs to the industry of automation measuring instruments. The disk display high-precision liquid level meter is characterized in that a magnetic float is arranged on an outer guide pipe of the liquid level meter; inner magnetic steel and a stainless steel transmission belt are arranged in an inner guide pipe; the magnetic steel arranged in the magnetic float in an outer guide pipe is corresponding to the inner magnetic steel; a casing body of the meter is connected with the top end of the outer guide pipe; a drum wheel, a high-precision potentiometer and an electric current converter are arranged in the casing body of the meter and are fixed to a bracket in a coaxial mode; the stainless steel transmission belt is connected with the head and the tail of the inner magnetic steel through both ends of the drum wheel for forming an annular steel belt. Because the rise and the fall of liquid levels, the inner magnetic steel moves upwards and downwards to form positive and negative rotary movement, and the pointer is driven to rotate for realizing the height change of the liquid levels. The utility model has the advantages of visual display, high precision and good practicability, and can be used in industries of petroleum industry, chemical industry, liquid gas industry, etc.
Description
The utility model relates to the automatic measurement Displaying Meter, especially for detecting the liquid level that shows internal tank.
The similar products at home and abroad structure all adopts the dynamic structure form that disc spring or weight rotate as pointer at present, and the former disc spring is not easy to keep permanent over a long time spring function, has a strong impact on the measuring accuracy of instrument; The dynamic structure form that latter's weight rotates as pointer, complex structure is not easy to make, whole assembling weak effect, transportation gets loose easily, and on-the-spot installation need be readjusted cumbersome.
The purpose of this utility model is to manufacture and design a kind of stable performance, and is simple in structure, and the precision height can intuitively and be realized automatic output information teletransmission, and the dish that is used for liquid level in the Microcomputer Detecting container shows the high-precision liquid level meter.
The utility model is realized by following measure: dish shows that the high-precision liquid level meter is by outer catheter, magnetic float, the stainless steel driving-belt, interior magnet steel, the steel band guide wheel, inner catheter, drum, instrument housing, panel board, big pointer, gear set, little pointer, the high precision multiturn potentiometer, current converter, support is formed, penetrate and be provided with stainless steel driving-belt and interior magnet steel in the inner catheter in the outer catheter, stainless steel driving-belt two ends and interior magnet steel join end to end and form the ring stainless steel driving-belt, outer catheter passes through magnetic float, the magnet steel that is contained in the magnetic float is corresponding with the magnet steel in the inner catheter, and will install in the outer catheter tank filling of magnetic float the usefulness ring flange from the flow container top fastening.The outer catheter top links to each other with instrument housing, have drum, gear set, high precision multiturn potentiometer, coaxial being fixed on of current converter to also have two steel band guide wheels on the support upper bracket below drum in the housing, the stainless steel driving-belt joins end to end by drum two ends and interior magnet steel through the steel band guide wheel and forms the ring stainless steel driving-belt.
This liquid level gauge is exported the DC4-20MA standard signal by the variation of high precision multiturn potentiometer resistance value and the current conversion of current converter.
Liquid level gauge is connected with photoelectric encoder and realizes digit pulse output and teletransmission high-acruracy survey.
Below in conjunction with accompanying drawing the utility model is done further detailed description:
