Eight, use and maintenance:

Use：

1, auxiliary instrument and accessories with the specific content of the corresponding instrument and accessories see instructions.

2, to prevent a distance or move away in the process of float moves up and down in the main duct damage, lateral supporting special steel factory calibration gauge (with color logo) will hold the magnetic float. So after receiving the product or after installation, please remove the correction magnet, so that the float can move along with the liquid level, before use if the magnetic reversal of inconsistent color correction, available the magnetic suction along the instrument can work normally.

3, level meter installed, with magnetic correction of magnetic guidance once to zero below zero above display red, white display.

4, level gauge according to user needs with a heating jacket or an electric heating device, such as when ordering does not select this option, and in the installation of self used heat pipe, temperature and mixed with heat generated by the device can not exceed the rated temperature level meter.

5, level meter into travel, should open the valve on the liquid guide pipe, and then, the liquid valve open long, 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 can be used to correct the magnet).

Maintain：

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

2, according to the media, the leading tube can be cleaned regularly, cleaning tube deposition of impurities.

3, clean or replace the float on the liquid, open the drain flange into the magnetic float, should pay attention to the heavy and magnetic end up not flip!

4, the low temperature liquefied gas and special products, vacuum jacketed insulation main body level meter, the installation process be careful not to damage the jacket, so as not to affect the quality of the products.

Nine, 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.

Ten, 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.

Eleven, 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.
