Disconnected current level value whether safe, is effectively improved safety coefficient.
Concrete: import double-colored ultra-bright LED display lamp includes red display lamp and green display lamp；
The LED pure color of Electro-Optical Display 8, will not paint face, display is clear bright, particularly exists
Show green pure on television monitoring, be different from common product and show situation about turning white on TV, reach
The most consistent to showing with TV on the spot, it is suitable for user's needs.And user can be carried out the most at the scene
Regulate brightness on a large scale, do not affected by site environment.Concrete: Electro-Optical Display 8 includes that one discharges into
The double-colored ultra-bright LED display lamp of mouth, for indicating the down or up of liquid level.LED supports hot drawing
Plug-in connection mode, changes spare part convenient, maintains easily.Wherein, when liquid level declines, described double
Color display lamp display redness, when liquid level rises, double-colored display lamp display green.
Electro-Optical Display 8 also includes a scale, scale and described import double-colored ultra-bright LED display lamp
It is arranged side by side, the correspondence scale label position, display position of described import double-colored ultra-bright LED display lamp,
I.e. numerical value representated by scale label position i.e. liquid level numerical value, the red green position according to luminous tube can from scale
Directly the upper concrete numerical value reading liquid level, facilitates related personnel and reads level value.
The cylinder of measuring cylinder 1 also includes the blow-off pipe 6 being located at cylinder bottom, blow-off pipe 6 row of being provided with
Dirty valve, blowoff valve is connected to reliable container, as measuring liquid or the emergency measure of gas leakage.
Electro-Optical Display 8, magneto sensor, liquid level transducer are connected to power supply 9.Used by the present embodiment
Power supply 9, its working condition: power supply mode: DC5V；Power consumption: ＜ 5W/m；Working life: >=10
Ten thousand hours；Use environment: 0～+60 DEG C；Electro-Optical Display 8 and electric box distance :≤10m.
It is more than concrete parts and the explanation of parts annexation of the present embodiment, the following is concrete reality
Operating instruction when executing.
Step S01: preparation, including following points for attention.
Open packing crates, careful operation, it is to avoid article in damage case.
After Kai Xianging, take out documents pouch, check the kind of article in case, quantity and outward appearance by packing list
With or without damage.
Take out liquidometer operation instructions, read over, in order to the guidance of by specification goes to install, debug.
In transportation, stress balance should be allowed to, carry or handling all should handle with care, avoid punching
Hit, prevent inner body from being impacted and damaging.
Step S02: the comprehensive inspection before liquidometer must being installed before installation, the cylinder of measuring cylinder 1
The internal foreign body that is not allow for enters.When float 4 loads cylinder, it should be ensured that float, without any damage, is sure not
Float 4 is turned upside down.Comprehensively after passed examination, install by Fig. 1 liquidometer scheme of installation,
During installation liquidometer centre-to-centre spacing to be proofreaded with container center away from the most consistent.
Step S03: liquidometer should be installed vertically on container, the perpendicularity of its axis requires less than 2 degree.
Step S04: when employing is welded to connect, should ensure that welding slag will not be retained in measuring cylinder 1, in order to avoid
Block float 4；When using Flange joint, red copper pad to be padded, wound gasket or dentiform gasket between flange.Blowdown
Valve to be received in reliable container (taking up testing liquid), it is to avoid liquid leaks.
Step S04: install probe tube.
First determine whether scale 7 scale on Electro-Optical Display 8 meets the requirements, then with float 4 near taking
Sample pipe 5 lower end, slowly moves up.When on Electro-Optical Display 8, first lamp of bottom becomes green
Time, determine whether the scale 7 scale numeral at the bright place of lamp meets the requirements, then bright with lamp on probe tube 5
Mark on the position that place's scale is corresponding, this labelling is placed in measuring cylinder corresponding with this scale
Position.Probe tube 5 rustless steel larynx banding is affixed on cylinder.It should be noted that there is magnetosensitive unit during fastening
The side of part faces toward measuring cylinder center.If showing incorrect, probe tube can be moved up and down.
Step S05: install Electro-Optical Display 8.
Electro-Optical Display 8 is fixed on the convenient position of observation, can be in measuring cylinder 1, it is also possible to be
Other position.
Step S06: after Electro-Optical Display 8 is fixing, connect probe tube 5, Electro-Optical Display 8 and power supply 9.
After switching on power, adjust required Electro-Optical Display 8 brightness by liquid level conversion dimmer 10.
Step S07: when liquidometer dispatches from the factory, the technical parameter provided according to user has carried out corresponding tune
Whole, if need at the scene to make to adjust more accurately, debug the most as follows: close when putting into operation
Blowoff valve and water valve, slowly open steam valve, makes gas slowly enter cylinder until valve is fully open,
Can't suddenly standard-sized sheet steam valve in case damage float 4.When cylinder internal pressure balances each other, go through liquid
Position is in respect of No leakage phenomenon.As there is no any problem continuing with debugging, if it find that problem must be made corresponding
Process.Checking after No leakage, slowly open liquid valve, make liquid slowly enter cylinder, display device should be with
In cylinder, liquid level slowly rises and shows that the red liquid of vapour is green, until float reaches balance liquid level.If liquid level
Indicate not rise tables prescribed liquid path not smooth, if liquid level rises very slow and can exceed that actual liquid level, show vapour
Roadlock plug, should immediately treat.Check and correction liquid level instruction correctness.Close steam valve and liquid valve, the slowly row of opening
Dirty valve, gets rid of liquid in cylinder, and the instruction of display liquid level should decline with liquid level and slowly decline, i.e. LED
Lamp reddens, until liquid emptying in cylinder, now LED all reddens.Close blowoff valve, again
Slowly open steam valve, the most slowly open liquid valve after steam valve is fully open and make liquid progress in cylinder, aobvious
It is normal for showing that the instruction of device liquid level should return to initial position.
Step S08: as it is shown on figure 3, the liquid level conversion dimmer 10 of this liquidometer self exports a road and has
Source 4～20mA signal, can connect DCS system, floats as scene needs warning can connect my company's telemetering type magnetic
Liquidometer secondary meter.This table has 8 tunnels warnings to export, and passive contact (220V/100mA) can be online
Arbitrarily set, automatic Memory.
It should be pointed out that, for this utility model through absolutely proving, also can have multiple conversion and change
The embodiment of type, it is not limited to the specific embodiment of above-mentioned embodiment.Above-described embodiment is only made
For explanation of the present utility model rather than to restriction of the present utility model.In a word, guarantor of the present utility model
The scope of protecting should include those to those skilled in the art obvious conversion or substitute with
And remodeling.
