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.
