ZW-UHZ-51R series <strong> of electric heating type magnetic level gauge</strong> is suitable for industrial production in the process of pressure (or open) liquid storage equipment (tower, cylinder, tank, spherical container and boiler) of the liquid level detection. Can display the work and all kinds of liquid level height.

The position signal transmitter can teleport with level, achieve the automatic control and measurement of liquid level by certain electrical installations. Meter level meter is a reliable safety. Because of the isolation of magnetic coupling sealed structure, especially suitable for the liquid level detection of flammable and explosive and corrosive toxic liquid, simple and safe and reliable so that the liquid level detection means the original complex environment change.

Liquid level meter has the characteristics of direct reading display, does not need to set level meter, can monomer for the whole range of measurement. The equipment has less holes, clear display, eye-catching signs, visual reading etc..When the liquid level meter with direct display instrument can save the intermediate transmission signal detection system to improve the transmission accuracy.

Two, work principle:

1, the basic type

ZW-UHZ-51R series <strong> of electric heating type magnetic level gauge</strong> according to the principle of buoyancy, the float with the liquid level measuring tube at the lifting up and down inside the float magnet by magnetic coupling effect, driving the red and white flip turn column 180 'level rises, turn column turned from white to red, down, turn column from red to white, so as to achieve the level of instruction.

2, limit switch output

The use of magnetic float with the liquid level gauge is installed in the mobile, the vertical tube set position switch, realize on-off control or alarm.

3, the electric remote

The magnetic level gauge transmitter installation. The sensor and transmitter converter is composed of two parts, the magnetic float moves up and down by the magnetic coupling of the measuring element in intraductal action, obtain the resistance signal changes, summoned into 0~10 or 4 ~ 20mA standard current signal output, and digital display connected to the instrument or computer, realize remote display and control.

7, anti-corrosion type: PP or PVC material, suitable for normal temperature and atmospheric corrosion resistant occasions.

Eight, installation, use and maintenance:

1, level gauge must be installed vertically, to ensure that the magnetic float movement in the main duct freely up and down.

A stop valve is arranged between the 2, the liquid level meter and the container, so that cleaning and maintenance to cut materials.

3, level gauge cylinder around a magnet close to not allow, otherwise it will directly affect the level of normal work.

4, level meter factory general insulation, but according to user needs for insulation, such as the user uses the hot mix line, must use the non-magnetic material.

5, to prevent the magnetic float transport at the leading high speed sliding tube to be hit, level meter factory, with Cathy will be fixed on the lower magnetic float liquid guide pipe, the user should be removed card silk can be installed prior to installation and use.

6, level meter installed, with magnetic correction of magnetic guidance once to zero below zero above the red, white

7, level gauge is put into operation, should open the valve on the liquid guide pipe, then slowly open under the liquid guide pipe valve, let the liquid medium smoothly into the main canal, avoid the liquid medium with a rapid rise caused by magnetic reversal failure or disturbed (in case of this phenomenon, the magnet available for calibration.)

8, open the bottom flange plate is installed in the magnetic float boring, heavy, should pay attention to end with a magnetic end up not flip.

9, level gauge cylinder should be solid impurities and magnetic impurities, so as to avoid jamming and weaken the buoyancy of the float.

10, according to the media, the leading tube can be cleaned regularly, remove sediment impurities in pipe.

Nine, the installation process:

1, after the factory, has assembled all the debugging, arrived at the scene, the first step must first clean up *, the need to install the equipment.

2, ready to install the necessary tools and bolts and manufacturers and distribution of the turning column indicates the calibration bar.

3, wipe scene flange, adjust equipment flange and magnetic level gauge flange on the straight, must keep the magnetic level gauge body vertical, and then put into the 4 hole bolt flange tool.

Ten, installation notes:

1, level gauge must be installed vertically, to ensure that the floating ball components in the main tube moving up and down freely.

2, level gauge around the main body does not allow the magnetizer near or directly affect level meter to work correctly.

3, level meter installed, need to use steel to correct a double bead guide to make zero position below zero above the display shows a red, white.

4, level meter running should first open the liquid guide pipe valve for liquid medium smoothly into the main pipe, avoid liquid medium with floating ball components caused by the rapid rise, turn turn bead failure and shuffle. If this occurs to the surface smooth available after re correction magnet.

5, due to the transport process in order not to float the component damage, before the factory will float out of the main pipe component level meter, liquid meter after installation, open the bottom discharge flange, then float assembly back in the main tube, pay attention to a heavy floating ball assembly on the head, not flip.

6, according to the media, can regularly open the sewage main pipe flange cleaning sediment.

Eleven, selection and installation:

1, we must first understand the equipment running their own situation, what is the measuring medium, even if they do not need to know what material, our company also can determine the material according to the medium used equipment.

2, when equipped with the remote meter to do the following, should make the remote meter to gauge leading tube, stainless steel hoop is fixed (disable iron); the remote meter should be on the surface should be oriented and close to the main duct; the remote meter should be zero and gauge zero instructions in the same horizontal line; remote meter and display instrument or computer connection alone wear protective pipe laying or shielding two core cable connection box; a wire inlet hole after laying, requires good sealing, in order to avoid rain, moisture intrusion and make remote matching instrument can not work normally, the junction box in the repair or completion of commissioning should be timely cover.

3, according to the media, cleaning the main duct to remove impurities;

4, for more than a certain length (common type > 3 meters, 2 meters, anti-corrosion type) of the liquid level meter, need to increase the middle reinforcement flange or lug fixed support, to increase the strength and overcome their weight;

5, magnetic position, board level meter should be avoided or away from materials import and export department, to avoid the rapid change of fluid material in local area, affecting the accuracy of liquid level measurement;

6, when debugging, should open the upper guide pipe valve, and then slowly open the valve at the lower part, so that medium smooth entry duct (to avoid the rush of media should be run in the float float, cause drama column fluctuation, affecting the display accuracy), observe the red ball magnetic flip is normal, and then close the lead pipe valve, open the drain valve so, the main duct level drops, according to the method, the operation three times, it is normal, can be put into operation (except special corrosive liquid); magnetic level gauge in the market there are other names, also called magnetic level gauge, or magnetic level gauge, also called magnetic float liquid level gauge. But they need to know the order parameter is certain, such as corrosive medium needs anticorrosive material, corrosion corrosion grade equivalent grade according to the changes of the medium. For example, the special situation of their own equipment, determine the installation mode of the magnetic level gauge, because some places do not fit or do not apply some installation methods.
