Steel strip is float liquid level gauge for level gauge proprietary technology introduced from abroa…

Products overview:

ZW - UZG seriesSteel belt float liquid level gaugeUsed in the oil industry is in the production process of a variety of liquid level meter, on the basis of research design and has the unique characteristics of the new product, new appearance design, small size, large power supply voltage range, strong adaptability, easy installation, on-site installation without hot, whether in use or new equipment can use, easy to install as instrument of steel belt is in the tank form the inner ring, as a result, affected by the ambient temperature change is small, and the instrument measuring precision is not affected by the liquid density and temperature change.

Second, the working principle:

ZW - UZG series steel belt float liquid level gauge 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.

In general have a mechanical sensor and the electronic processing, sensing part is through the float, float in the measurement process is floating on the liquid), as measured on the surface of the fluid lift and elevator, make on the float with closed-loop stainless steel belt drive the positive and negative direction measuring wheel for measuring wheel and reversing Angle is proportional to the float lifting distance and Angle of the design discharge wheel for L/W

Among them: L - float up or down

W - by measuring wheel Angle corresponding to the arc length

Balance here damper has two functions, one is a constant tension for the steel, avoid steel belt and measurement of sliding between wheel;The other one is when the liquid level fluctuation, fluctuate formation fluid, prevent rapid jitter of float, and stable float in the correct position.

Measuring the rotation of the wheel by magnetic coupling to the electronic processing module, the corner into the corresponding voltage.

Applications:

ZW - UZG series steel belt float liquid level gauge can be widely used in petroleum, chemical, electric power, metallurgy, environmental protection, food and other industrial departments and affiliated facilities of all kinds of connections in the transmitter, liquid level change converts analog signals from the container, electric pulse signal or switch signal remote transmission to the control room to display or data display and processing in the computer room.

Four, the main features:

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.Four, unique advantages:

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, 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;

Six, 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.

Seven, to install and use:

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.

8 and 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.

Eight, selection of code:

Nine, design selection and order need to know:
