Abstract

The utility model relates to a magnetic-sensing switch high-precision floater type color band liquid level meter, which is characterized in that a liquid tank is communicated with a pipe body. The pipe body provided with a magnetic floater is connected with a meter cover provided with a dial, a color band, a color band wheel, a wire rope, a wire rope wheel and a magnetic-sensing switch. The magnetic floater in the pipe body is corresponding to the magnetic-sensing switch. When the magnetic floater moves up and down, the magnetic-sensing switch switches an on-off circuit on to control a reversible motor to drive the color band to tracking the magnetic floater to move up and down. The automatic measurement to the liquid level or an interface can be achieved. The magnetic-sensing switch high-precision floater type color band liquid level meter has the advantages that an integral structure of magnetic-sensing devices and the electromechanical technology is used. The utility model has the advantages of good practicability, low cost and visual and striking display of the color band. The magnetic-sensing switch high-precision floater type color band liquid level meter is not easy to malfunction and has the functions of night viewing and remote-control warning. The magnetic-sensing switch high-precision floater type color band liquid level meter can be connected with a microcomputer to conduct the measurement of the liquid level of a tank group and is suitable for the industries of petroleum, chemical engineering, pharmacy, light industry, boilers, etc.

Description

Magnetosensitive switch high precision float-type colour band liquid level gauge

The utility model belongs to measurement, Displaying Meter, is used to detect the liquid level that shows the liquid level internal tank.

Domestic and international at present traditional float liquid level (flow) meter adopts the on-the-spot demonstration of pointer-type, its structure transmission complexity, manufacturing cost height with teletransmission more, service precision needs compensation, glass ball float formula liquid level (flow) meter can only be used for on-the-spot the demonstration, can not realize the metering of teletransmission and continuous integration.

The purpose of this utility model is to manufacture and design a kind of scene intuitively to show, also teletransmission automatically is used for the magnetosensitive switch high precision float-type colour band liquid level gauge that Microcomputer Detecting tank battery liquid level (flow) is measured.

The utility model is realized by following measure:

Magnetosensitive switch high precision float-type colour band liquid level gauge is by body, magnetic float, watch glasses, the colour band wheel, colour band, compress the clamp assembly, the tension spring, magnetosensitive (on, switch down), wire rope, wire rope pulley, compositions such as multiturn potentiometer, flow container and body link, be provided with magnetic float in this body, body one side and watch glasses join, be provided with dial plate in the watch glasses, on, following colour band wheel and on, following wire rope pulley, the wire rope two ends be connected to respectively magnetosensitive (on, down) switch and join with the tension spring by wire rope pulley circularizes, the annular colour band links with compressing the clamp assembly by the tension spring two ends on colour band wheel and the wire rope, the magnetosensitive switch is corresponding with the float in the body, the magnetosensitive switch links by connection lead and on-off circuit and just controls reversible electric machine, reverse rotation, driving wire rope makes its colour band that is connected together mutually move up and down with liquid level by wire rope pulley, to realize that the colour band wheel is fixedly connected with multiturn potentiometer to liquid level (flow) measurement automatically.

Magnetosensitive (upper and lower) switch in the watch glasses is corresponding with the magnetic float in the body, is provided with two fritter magnet steel in the magnetic float.

The electric power system of magnetosensitive switch high precision float-type colour band liquid level gauge can adopt sun power as power supply power, also can directly use DC power-supply system.

Description of drawings:

Fig. 1 is an one-piece construction synoptic diagram of the present utility model;

Fig. 2 is a dial plate synoptic diagram of the present utility model.

Among the figure: 1 body, 2 magnetic floats, 3 watch glasses, 4 colour bands are taken turns 5 colour bands 6 and are compressed clamp assembly 7 tension springs 8 magnetosensitive switches 9 magnetosensitive switches 10 connection leads 11 on-off circuits 12 wire rope 13 wire rope pulleys 14 multiturn potentiometers 15 dial plates 16 reversible electric machines 17 magnet steel

Below in conjunction with accompanying drawing embodiment provided by the utility model is described further:

Flow container and body 1 link, be provided with magnetic float 2 in this body, body one side and watch glasses 3 join, be provided with dial plate 15 in the watch glasses, on, following colour band wheel 4 and last, following wire rope pulley 13, wire rope 12 two ends be connected to respectively magnetosensitive (on, switch 8 down), 9 and join and circularize by wire rope pulley and tension spring 7, annular colour band 5 links with compressing clamp assembly 6 by the tension spring two ends on colour band wheel and the wire rope, the magnetosensitive switch is corresponding with the float in the body, be provided with two fritter magnet steel 17 in the magnetic float, the magnetosensitive switch links with on-off circuit 11 by connecting lead 10, on-off circuit and reversible electric machine 16 join, because the magnetosensitive switch in the watch glasses is corresponding with the magnetic float in the body, when magnetic float changes with the liquid level lifting, the magnetosensitive switch moves thereupon, make reversible electric machine just by on-off circuit, backward rotation, wire rope makes it be associated in together colour band along with liquid level moves up and down by wire rope pulley, at this moment the mark on the colour band can demonstrate the true altitude of liquid level in the flow container, on dial plate 15, read precise number, realize automatic measurement liquid level (flow).The colour band wheel links with multiturn potentiometer 14, when the magnetosensitive switch motion, colour band is LINEAR CONTINUOUS with the liquid level lifting and shows, liquid level change is translated into resistance absolute value linear change, realize the output of 4-20mA standard signal by the R/l modular converter, reach the metering that utilizes Microcomputer Detecting liquid level (flow), and can adopt CR to show.

The utility model has the advantage of: this instrument adopts magnetosensitive device and mechanical ﹠ electrical technology integral structure, and is floating in the body Son is in the free floating state, links without pull rope, is difficult for breaking down, precision height, accuracy of reading, and night vision is arranged Function, colour band intuitive display, eye-catching, stability is reliable, and round the clock distant surveillance of convenient operation personnel simultaneously can Signal is transported to the control room realizes the far distance controlled warning function with secondary meter, also can link with microcomputer and patrol and examine Many liquid levels (flow) metering is applicable to the industries such as oil, chemical industry, electric power, light industry, pharmacy boiler.
