Products overview:

ZW - UZG seriesSteel belt level meterAs liquid level gauge proprietary technology introduced from abroad, the domestic production of industrial container liquid level meter, can be on the instructions of the level measurement, can also according to customer requirements standard transmitter.With strong practicability, large measuring range, high performance and stable precision, long service life, easy to maintain, etc.In addition, a large counter displays, make clear reading accuracy;Manual float ascend, may at any time check instrument working condition;Can be connected with a variety of transmitter, liquid level detection system.

Second, the working principle:

ZW series - UZG steel belt level meter is a kind of traditional liquid level gauge.It is the use of mechanical balance principle of design and production.It is by the liquid level detection device, the high precision displacement transmission system, constant force device, display device, transmitter devices and other peripherals.

1, dip in the measured liquid float W by gravity, buoyancy and F by the effects of the constant tension of T constant force device, when three force vector and is equal to zero, float in the quasi equilibrium static state.Mechanical equilibrium of buoyancy is quasi-steady (float into the liquid volume V is constant value).

2, when the liquid level changes, the original mechanical equilibrium under the float by the buoyancy of the disturbance, through the movement of the steel strip reaching a new equilibrium.(float) according to the level of the liquid level detection device drives the moving steel strip, the displacement of the transmission system working through the movement of the steel belt drive pin rotation, which ACTS on the counter to display the level of the situation.

3, the liquid level transmitter is converted into standard electric signal, through the signal output.The electrical signal can drive other control devices.

Applications:

ZW series - UZG steel belt level meter: yes, it is a kind of simple liquid level measuring instrument, it is widely used in petroleum, chemical industry, electric power, metallurgy, medicine, water supply, etc used for storage of corrosive liquid in the tank, tank and other flat arch container with water tower water level (interface) measurement, solved the tank level measurement and using artificial roof steel measurement difficulties and other issues, and can obtain accurate measurement results, can be measured medium acidic, alkaline or high viscosity.This instrument has the appearance of simple structure, high measurement precision, liquid level display intuitive, clear, no blind area, can be observed over a long distance, is an ideal instrument to level measurement.

Four, the main features:

1, simple structure and beautiful shape, firm, installation, convenient operation.

2, intuitive, striking, reading can be observed over a long distance.

3, large measuring range, no blind spots.

4, can be measured medium with strong corrosion, high viscosity.

Five, classification and scope of use:

1, the product according to the use function can be divided into two types, regular and blocking, and its use scope is as follows:

A, ordinary is mainly suitable for corrosive or toxic gas overflow occasions;

B, blocking type is mainly suitable for corrosive or toxic gas overflow.

2, the product can be divided into the form of the connection flange connection type and threaded connection type two kinds, the use scope is as follows:

A, flange connection type is mainly used in the measured medium for corrosive or toxic liquids occasions;

B, threaded connection type is mainly applied to atmospheric pressure, no corrosive or toxic gas overflow.

Six, the technical parameters:

1, the ambient temperature (℃) : - 40 ~ 85 (transmitter);

2, relative humidity (%) : 5 ~ 100 (including direct wet gel);

3, atmospheric pressure (KPa) : 86 ~ 108;

4, (m) : measuring range 0 ~ 6, 0 ~ 12, 0 ~ 18, 0 ~ 20;

5, the error of measurement (mm) : 4.5 mm;

6, sensitivity (mm) : 1.5;

7, working pressure (KPa) : 0 ~ 17.5;

8, medium temperature (℃) : - 40 ~ 200;

9, display mode: 10 m, m, dm. Five digits, centimeters, millimeters, by three display counters, and dial

10, contact medium material: 1 cr18ni9ti;

Seven, installation requirements:

1, the selected float installation position should be paid attention to the following questions: (1) should be easy to installation, debugging, readings, and maintenance, to near the manhole, oil hole or special mounting plate zui hand touches such as part of the good.(2) the float from the size of the container wall should conform to the requirements of the appended drawings, when in special circumstances, can not affect the instrument performance under the condition of appropriate treatment.(3) working location should be far away from the discharging mouth of float and mixer, in order to prevent the liquid level fluctuation affect the measuring accuracy and stability.Is inevitable, to design for installing shunt, wave shields and other devices.

2, float, after the confirmation of the installation position of the steel strip was established according to the level of physical size the length of the duct size.Steel belt catheter use 1 1/2 "water gas conveying or galvanized pipe, connected to the header, the elbow and take over for the R1 1/2" threaded.

3, header with thread and take over the connection directly, don't need to add support fixed;If the user to design and manufacture of protective eaves or protective tube to prevent direct and reliable work will be more conducive to the instrument.

4, steel belt catheter (user should bring along their own, or manufacturer of the inner surface to prevent rust after cleaning and have a protective coating.

5, install steel pipe should be paid attention to with ducts perpendicularity error should not be greater than 5 mm.

6, ZW - UZG100, ZW - UZG101, ZW - UZG104 catheter stents welding in the tank wall;ZW - UZG106 catheter stents with bolt and the tank wall Angle (the user should bring along their own).

7, instrument back cover and the tank wall vertical, so that when installing a transmitter instrument there is enough space behind.

Eight, adjustment and using:

1, user product after the arrival of the goods shall, first of all, check the packaging quality of products, packing should be intact, mark clear;For packaging has obvious damage shall timely notify the shipping department or to the factory find out problems and responsibility, if no packaging quality problem, pull products out of the box.

2, the user should be selected according to the instrument type and range of corresponding reading about the terms of the requirements in this manual, correct installation, adjustment and using.When installation, can consult installation diagram for installation.

3, according to the installation site, referring to the actual size of liquid level meter, determine the installation position of the instrument;And to determine the length of the duct size 1 1/2 "steel, processing good R1 1/2" threaded end, inside surface should be galvanized or painted anticorrosive paint, used for installation.

4, steel belt catheter connector in connection with ptfe teflon tape auxiliary seal.

After 5, instrument installation, can adjust the counter displays according to user's actual requirement.

6, began to container pumping medium, should be slow to prevent excessive impact damage the float and other parts.

After 7, instrument installation, can adjust the counter displays according to user's actual requirement.According to the nameplate indicating the direction of the rotating header positive handwheel 1/4 circle can be a little mention float, the meter reading should be change, instrument working properly, can be put into use.

Nine, maintenance:

1, for the correct installation of instrument in good working environment, except on the surface of the daily maintenance, usually no special maintenance.When the measured medium is pollutants may stick by float on the surface, or other parts should be regular cleaning, in case the instrument work down.

2, instrument of rotational parts often should add a small amount of lubricating oil for lubrication.

3, in equipment overhaul should be removed when the instrument cleaning, and replace the aging of rubber seals, so as to ensure the reliability of the instrument of sealing and work.

4, long-term use of the instrument should be replaced regularly wearing parts.

Ten, selection of code:
