ZW-UHZ series Magnetic float level meter From the instructions part and auxiliary device (liquid level control switch and a liquid level remote transmitter) is composed of two parts, the user can also use the instrument can be used to separate the medium level of various tower, tank, tank, spherical container and boiler equipment testing etc.. The level of the series can be high seal, leak proof and suitable for high temperature and high pressure, corrosion resistant occasions. It is made up of glass plate (tube) liquid level meter indicating defect clarity is poor, easy rupture, and the measurement process without blind area, clear display, large measuring range. The measurements show that the part is not in direct contact with the media, because of high temperature and high pressure, toxic, harmful, strong corrosive medium, more show its superiority. Therefore, it is the traditional glass plate (tube) liquid level meter has higher reliability, safety, advancement and practicability.

The magnetic flap is suitable for all kinds of industrial production process pressure (or open) liquid storage equipment (tower, cylinder, tank, spherical container and boiler liquid level detection of liquid medium). Can display the work and all kinds of liquid level height.

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 series <strong style="white-space: normal;"> of magnetic float level</strong> according to the principle of buoyancy and magnetic coupling developed. When measured in the container level lift, liquid level gauge leading tube float with lifting, the permanent magnets in float through the relay to the magnetic coupling indicator, drives a red and white turn column flip 180 degrees, when the liquid level rises, turn column turned from white to red, when the liquid level drops, by turning column red to white, red and white circles indicator at the actual height of the medium level in the container, so as to achieve the level of instruction.

Eighth, classification and application:

1, insert type magnetic level gauge: liquid level measurement and control of the liquid level gauge is suitable for underground tank, pool.

2, insulation type magnetic level gauge: the liquid level meter is installed a thermal insulation jacket and a steam heat medium in the main base outside. The normal flow of liquid in the body can be maintained. The liquid level measurement and control so it is suitable for easy solidification of liquid. For low boiling point liquid can pass into the cold water as refrigerant agent, to ensure the stability of liquid level. The instrument correctly indicates the measured level.

3, frost proof magnetic level gauge: our factory specially designed for solving the liquid level of cryogenic liquid meter ice products. The insulation jacket is vacuum layer. It can effectively isolate the cold and heat conduction. The main gauge tube does not freeze, frost. In order to ensure the normal use of liquid level meter.

4, strong corrosion resistance type magnetic level gauge: all parts in contact with the medium of the level meter adopts steel plastic composite pipe. All can be applied to various corrosive medium level measurement and control.

9, 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 need to 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 the remote meter 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, the installation location, should avoid the material medium or away from the 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, 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!
