Products overview:

ZW - UGS seriesQuartz tube liquid level meterIs to adopt a new technology developed at home and abroad.It is the use of natural light refraction principle, reflection in the liquid, with the aid of red, green, in the measurement, to bring green liquid, gas phase shown in red.Instructions, because of the large liquid gas phase display contrast bright and clear, so more advantageous for remote operation and night patrol.If with LED light source is displayed more clearly.At the same time for the two kinds of different medium density interface measurement, can choose three color interface quartz tube liquid level meter.Three color interface quartz tube liquid level meter is designed by using the principle of buoyancy and the proportion difference, quartz tube in the small float suspended in the boundary of two kinds of medium section, due to float in black, upper and lower part of the liquid color is different, so the display eye-catching.So as to solve the has plagued in petrochemical process distinguish between two kinds of hybrid medium interface problem.It is the ideal direct reading type level gauge at home and abroad.

Second, the working principle:

ZW - UGS series special special-shaped quartz tube liquid level meter is mainly composed of quartz glass tube, filter the green glass, the table body, the upper and lower valve and drain valve.Liquid level meter and the vessel flange connectors, through the optical principle of refraction and reflection of natural light in the liquid, with the help of red, green glass screen liquid brings green, red gas phase.Red, green and show clear, can be in remote observation and observation at night.

Working principle for different liquid light's difference and the relationship between the density difference, using color level of optics refraction principle, achieve the purpose of the three color display interface, and the interface between the two kinds of the liquid surface buoy floating in a color, make the two distinct interface.

Eight, classification and scope of application:

1, general motors has no blind area double color quartz tube liquid level meter:

Is mainly composed of flanged explosion-proof Angle valve, flexible pipe, sheet, special-shaped quartz tube, filter board, drain valve etc.Its characteristic is widely used, beautiful and easy, easy installation, durable.

Applicable to a variety of conditions, the corrosion of carbon steel or 304, 1 c18ni9ti, 316 l licensing media are optional.Such as water, gas, oil and other hydrocarbons, saline solution, dilute acid and other organic and inorganic medium.

2 three color quartz tube liquid level meter, float: special manufacture of small float in the quartz tube floating in liquid-liquid interface, at the same time also can steam the red liquor green indicator level.Suitable for low viscosity medium, such as liquefied petroleum gas - water and light oil - water and chemical solvents.Liquid-liquid medium proportion difference is greater than 0.2 g/cm.

3, floatless three color quartz virtuosos potentiometer: special manufacture of quartz tube can use water and refractive index of oil, with red and green indicate oil and water respectively.Suitable for gasoline, kerosene, diesel oil - water interface instructions.

4, PP anti-corrosion double color quartz tube liquid level meter, mainly composed of flanged PP explosion-proof Angle valve, table, double color quartz tube, screen plate, etc.The main features of which is carbon steel, has high strength, light weight, beautiful and durable, strong anticorrosion performance.Temperature and pressure is not high and allowed for PP corrosion medium are optional, such as power plants, high concentrations of hydrochloric acid and other corrosive medium.

5, fluorine plastic anticorrosive double color quartz tube liquid level meter, mainly by the special lining fluorine plastic tee, table, double color quartz tube, screen plate, etc.Its characteristic is not using carbon steel, not only has high strength, and because the medium was all fluorine plastic isolation, zui strong anticorrosion performance, beautiful appearance.Suitable for almost all the corrosive medium.

Six, storage tank is special wide visual surface double color quartz tube liquid level meter (center distance) :

Due to the limited by the length of the quartz tube, quartz tube liquid level meter is not commonly may do very long, so when the tank liquid level measurement is often made dendritic a communicating pipe, weight big and observation inconvenience.This product use number can be connected with the liquid level meter is clever.Compact structure, light weight, wide, show clear.In low density measurement medium, after specially designed never vaporization phenomenon.Deficiencies are two middle blind area about 40 mm, but because it is double color, according to the blind area affect little.Applicable to the storage tank, including low density media such as liquefied petroleum gas in a variety of media.

Nine, the level of transportation, storage, installation, use and maintenance:

Water level gauge can be used after 1, packaging conventional transportation tool, but should avoid violent vibration and snow and rain erosion directly.

2, water level gauge should be on temperature 0 ~ 40 ℃, relative humidity is not more than 80% of the dry and ventilated indoor and outdoor air should not be mass containing corrosion instrument.

3, water level gauge must be installed vertically, the vertical deviation degree should be less than 3 °.

4, gauge and container should be equipped with stop valve, so that with the dielectric isolation during the cleaning and maintenance.

5, according to media, should be conducted on a regular basis of ontology pipe cleaning, removal of tube of sundry.

Ten, use and replacement items:

1, the quartz tube is mainly used for all kinds of pressure vessel, industrial steam boiler liquid level display.In transport, storage, picking, all need to be careful not to use when putting high hit heavily quartz tube, do not use sharp or rough grind arenaceous kind of items contact quartz tube, maintain the level of play is smooth, transparent, high visibility.

2, the installation of the quartz tube is very simple, it includes the valves, valve, drain valve and the reading of the main color quartz tube, when installed, just need to up and down the valve flange port respectively corresponding to the corresponding port of boiler installed, tighten can complete the installation.

3, when used, enable the level for the first time, you will need to open the drain valve, make the liquid will pass directly discharge valve, then open the valve on half a circle, make the quartz tube wall for a few minutes of preheating, especially in cold temperature of the environment, preheating time must be enough, at the same time in the preheated operation, operators should be located in the liquid level meter on the side, in order to prevent the accident from happening.

4, after preheating, close the drain valve, can open the valve at this time, the extent of the normal operation of the valves are open to, make the liquid level meter into the normal working condition.

5, if there is a need to be replaced in a state under the level of boiler operation, you need to pay attention to open the boiler on the cut-off valve, the cut-off on both sides of the exchange, then shut down the level of upper and lower valve, open the discharge valve, then the corresponding change.
