Abstract
The utility model discloses a liquid level measuring device. The liquid level measuring device is high in measurement precision; and influence on measurement precision due to shaking of a liquid level can be avoided. The liquid level measuring device comprises a micropulse displacement sensor, a support and a filter drum, wherein the micropulse displacement sensor comprises a measuring head, a measuring rod and a floater sleeved on the measuring rod; the support is sleeved on the top of the measuring rod and is fixed by a locking nut arranged on the measuring rod; the support is provided with a mounting bolt; the upper end of the filter drum is in contact with the support; the lower end of the filter drum is an opening end; and a filter screen is arranged at the opening end, and is supported and positioned by a tail end fixing bolt arranged on the bottom of the measuring rod.
Description
Technical field
The utility model relates to a kind of liquid level emasuring device.
Background technology
At present, liquid level is controlled the magnetic switch that the liquid level gauge using adopts dry reed, is switching value output, and measuring accuracy is low, can not demonstrate in real time the variation of liquid level.In order to show in real time that liquid level changes, improve measuring accuracy, developed micropulse displacement transducer.Micropulse displacement transducer comprises measuring head, sounding rod and is enclosed within the float on sounding rod.This micropulse displacement transducer is mainly that application magnetostrictive liquid level measuring technique this contactless observation and control technology is accurately measured the actual value of tested medium liquid level in the absolute position of detected activity float.Float is placed in testing liquid, when liquid level changes, float moves up and down along sounding rod, measuring head can pass to control system by signal after receiving signal, by control system, convert the absolute value signal of liquid level in container to, this signal is both as the real-time demonstration of liquid level, also as liquid level monitoring.But current this micropulse displacement transducer in use, owing to being noncontact between float and sounding rod, float is easily subject to the surge impact that liquid level produces, and rocking that namely liquid level occurs can cause rocking of float, and then affects measuring accuracy.
Utility model content
The technical matters that the utility model solves is to provide a kind of liquid level emasuring device of avoiding slosh to exert an influence to measuring accuracy of being conducive to.
The utility model solves the technical scheme that its technical matters adopts: liquid level emasuring device, comprise micropulse displacement transducer, micropulse displacement transducer comprises measuring head, sounding rod and is enclosed within the float on sounding rod, also comprise support and filter cylinder, support casing is connected on the top of sounding rod and fixes by the set nut being arranged on sounding rod, on support, be provided with erection bolt, the upper end of filter cylinder contacts with support, the lower end of filter cylinder is openend, open end is provided with filter screen, and filter screen is by the tail end set bolt supporting and location that is arranged on sounding rod bottom.
Further: micropulse displacement transducer is connected with controller, controller is connected with alarm.
The beneficial effects of the utility model are: liquid level emasuring device of the present utility model not only can accurately record the actual value of liquid level, and owing to being provided with filter cylinder, can avoid slosh to have a negative impact to measuring accuracy.And the utility model is easy for installation, be convenient to maintenance.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of liquid level emasuring device of the present utility model;
In figure, be labeled as: measuring head 1, erection bolt 2, support 3, float 4, filter cylinder 5, sounding rod 6, filter screen 7, tail end set bolt 8, set nut 9.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.
As shown in Figure 1, liquid level emasuring device of the present utility model, comprise micropulse displacement transducer, micropulse displacement transducer comprises measuring head 1, sounding rod 6 and is enclosed within the float 4 on sounding rod, also comprise support 3 and filter cylinder 5, support 3 is socketed in the top of sounding rod 6 and fixes by the set nut 9 being arranged on sounding rod, on support 3, be provided with erection bolt 2, the upper end of filter cylinder 5 contacts with support 3, the lower end of filter cylinder 5 is openend, open end is provided with filter screen 7, and filter screen 7 is by tail end set bolt 8 supporting and locations that are arranged on sounding rod bottom.Filter screen 7 makes above-mentioned filter cylinder 5 integral body obtain tail end set bolt 8 supporting and locations by tail end set bolt 8 supporting and locations that are arranged on sounding rod bottom.Owing to being provided with filter cylinder 5, when the liquid level of filter cylinder outside shakes, the liquid level of filter cylinder 5 inside can not rock substantially, can effectively avoid rocking of float 4 like this.
When above-mentioned liquid level emasuring device is used, device integral installation, at the top of tested container, is connected device by erection bolt 2 with tested container.Then micropulse displacement transducer is connected with controller, controller can be PLC switch board.Then in PLC program, increase corresponding control program, and debug measurement precision.Finally can come into operation.
On the basis of the above, when liquid level variation exceeds preset value, in order to know in time, micropulse displacement transducer is connected with controller, and controller is connected with alarm.
Watchdog routine in above-mentioned controller can comprise:
1) liquid level converts: the overall height of container (L1) deducts displacement transducer output absolute value (L2) and adds that a deviation (Le) is exactly the true altitude value (L) of liquid level, L=L1-L2+Le; For preventing disturbing, use wave filter output;
2) liquid level shows in real time: the level value obtaining after converting is delivered in control station dependent picture and shown in real time;
3) warning of liquid level bound and shutdown: the level value obtaining after converting and liquid level bound alarming value and the shutdown level value of pre-defined (can on picture, input adjustable parameter) are compared, after exceeding, send be correlated with alerting signal indication;
4) liquid level is monitored in real time: in a gap periods of liquid level monitoring, when the variable quantity of liquid level is greater than predetermined threshold value, in i.e. judgement system, there is leak case that continue or burst, now liquid level monitoring function is sent alerting signal and is stopped the operation of this fluid system, records current real-time level value simultaneously and shows on workstation.
Claims (2)
1. liquid level emasuring device, comprise micropulse displacement transducer, micropulse displacement transducer comprises measuring head (1), sounding rod (6) and be enclosed within the float (4) on sounding rod, it is characterized in that: also comprise support (3) and filter cylinder (5), support (3) is socketed in the top of sounding rod (6) and fixes by the set nut (9) being arranged on sounding rod, on support (3), be provided with erection bolt (2), the upper end of filter cylinder (5) contacts with support (3), the lower end of filter cylinder (5) is openend, open end is provided with filter screen (7), filter screen (7) is by tail end set bolt (8) supporting and location that is arranged on sounding rod bottom.
