Far eastone steel belt level meter

Products overview:

ZW - UZG seriesProprietary technology introduced from abroad, after localization of the autonomous production of industrial container liquid level gauge.Reliable mechanical transmission, the use of installation, large measuring range, in addition, a large counter displays, makes 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.In the midst of liquid level meter, a long service life, easy to maintain.According to project needs, combined with remote transmitter use, can be realized on the digital display, as well as the standard of 4 ~ 20 ma output far eastone electrical signals, to match the recording instrument, or the needs of the industrial process control.

Second, the working principle:

ZW series - UZG far eastone 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.

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).

When the liquid level changes, the original mechanical equilibrium under the float by the buoyancy of the disturbance, will move through the steel strip of 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.Transmitter converts this level into standard electric signal, through the signal output.The electrical signal can drive other control devices.

Applications:

ZW series - UZG far eastone steel belt level meter 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.

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

10, contact medium material: 1 cr18ni9ti.

Six, 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.

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.
