Abstract
The utility model relates to a meter which can measure height of liquid level or liquid capacity automatically, comprising a liquid level measuring element manufactured by magnetic control variable-resistance technique, a connecting wire and a display meter. The measuring element is composed of a floater and a sliding tube. When liquid level varies, an iron ball in the sliding tube is caused to be lifted following liquid level under the magnetic pole function in the floater, and thus electric resistance is varied and a signal is sent to the display meter. The magnetic control variable-resistance liquid level indicator has the features of refining structure, reliable operation, easy maintenance, low manufacturing cost, and can transfer a linear liquid level signal continuously in long distance in the environment with high temperature, high voltage, easy explosion and strong corrosive medium, and thus can be widely applied to productions in the industries, such as petroleum, petrifaction, chemical engineering, pharmacy, paper making and food product.
Description
The utility model relates to the instrument of a kind of automatic measurement liquid levels height and liquid in storage tank capacity.
At present, commercial production is used liquid level in respect of float-type, mixed cartridge type, differential pressure type, condenser type, electric pole type, radiant type, ultrasonic type liquid level meter, the liquid level meter of these kinds all exist to be difficult for remote signal, the complex structure of transmitting respectively, and cost height, function can not be steady in a long-term, operation and maintenance is subjected to weak points such as various restrictions.
The purpose of this utility model is that a kind of cost is low, reliable, maintenance is simple and convenient for liquid level metering and volumetric metering work in the commercial production provide; Can pass linear signal at a distance; The various environment that can adapt to high temperature, high pressure, the explosive and medium that is corrosive; New-type and practical measurement instrument.
The utility model is made up of measuring sensor, lead and indicator gauge, joining place with slip pipe in the floating drum of measuring sensor is provided with magnet, the slip pipe top that is positioned at the fluid reservoir inboard is fixed on the fluid reservoir flange, the resistive conductor that is arranged on the slip pipe inwall links to each other with the connection terminal of indicator gauge by lead, the slip pipe inner chamber also is provided with hollow iron ball, and floating drum floats on the liquid; In the slip pipe for vacuum or be filled with dry oxygenless gas sealing; Can add the drying agent sealing in the slip pipe.
The utility model compares with the various liquid level meters of using at present, it is far away to have the signal distance of transmission, signal is transmitted continuously, easy for installation and liquid body proportion variable effect not is to fluid to be measured and strong, simple in structure, the easy maintenance of environment for use adaptability, characteristics such as cost is low, reliable, the life-span is long.
Below in conjunction with accompanying drawing the utility model is further described:
The utility model is by the level gauging element that adopts magnetic control change resistance technology to make, and lead and Displaying Meter formation.The level gauging element is made up of the floating drum slip pipe middle with being through floating drum, and floating drum uses lower edge slip pipe lifting at fluid to be measured buoyancy.According to temperature, pressure, corrosive medium and requirement of explosion proof, floating drum and slip pipe available copper, lead, stainless steel, Titanium and the higher plastics of various intensity are made.A side is installed powerful permanent magnet poles in the floating drum, and opposite side is established balance weight device.Lay resistive conductor in the slip pipe, and movable thin-walled iron ball is housed.When floating drum during with the level change lifting, the lightweight iron ball resistive conductor scroll-up/down that thereupon reclines in the poles attract slip pipe.Because iron ball plays the short circuit effect, so can change resistance value, the resistance variations signal is sent away Displaying Meter through lead, in indicator gauge, can read liquid level or liquid capacity through converting.Certainly, resistance signal also can be delivered to regulator, and the realization liquid level is controlled automatically.Indicator gauge can be selected ratiometer, colour band indicator, self-balancing bridge circuit, nixie display for use.But resistive conductor coiling formula or rail mounted in the slip pipe.Iron ball also can use roller.For holding contact cleans for a long time, vacuumize in the slip pipe or fill the sealing of dry oxygenless gas, also can add the drying agent sealing.
The utility model principle of work is achieved in that
When liquid level body 7 liquid level change in the fluid reservoir 1, floating drum 6 changes height along slip pipe 2 thereupon.Owing to iron ball 4 attraction force acts in the 5 pairs of slip pipes of magnetic pole 2 that are installed in floating drum 6 inside, iron ball 4 also changes with liquid level change.Iron ball 4 is short-circuit contacts of resistive conductor 3, and the iron ball position change makes measured resistance value also with liquid level change, indicates liquid level or liquid capacity numerical value by lead 8 at indicator gauge 9.
The utility model embodiment is to select powerful permanent magnet poles for use, makes the hollow light iron ball, adopts parallel or screw arrangement resistive conductor method, and dry gas or drying agent measure are taked to vacuumize, filled to slip pipe, guarantee contact non-corroding.
