Abstract
The utility model relates to a protecting filter pipe device for a cable/rod type level meter, which is characterized by comprising a protecting filter sleeve and a connecting flange of a filter pipe, wherein the connecting flange is arranged at the top of the protecting filter sleeve; measuring holes are formed at the bottom of the protecting filter sleeve to fix a sonde of a level meter; a plurality of filtering holes are uniformly distributed in the wall of the protecting filter sleeve; the connecting flange is matched with a tank body flange. The device has the advantages that the structure is simple, the measuring stability can be improved, the service life of a liquid level meter can be prolonged, besides, users can design and process as per the lengths of a level meter cable/rod and a measuring sonde both actually used, the demounting and mounting are simple, and the maintenance is convenient.
Description
Technical field
The utility model relates to field of measuring technique, relates in particular to cable/rod-type level meter protection filtering tube device.
Background technology
at present, in field of measuring technique, the level gauging technology adopts more instrument that following two kinds of level meters are arranged: the ⑴ static pressure drops into (cable) formula liquid level gauge: this product is because profile is small and exquisite, light, measure sensitive, be widely used in urban water supply and sewerage, the water treatment plant, reservoir, the river, the ocean, storage tank, tank and the oil of pastel are housed, chemical industry, metallurgical, the level gauging of the liquid level of the departments such as electric power and other open container liquid, has installation, use, the advantage such as easy to maintenance, but higher to requirement for environmental conditions, must be clean in the measuring media of measuring sonde contact, stably under situation, guarantee level gauging data are accurate, liquid level gauge is longer serviceable life.Yet in factory's practical application, most of level gauging media are dirtier, fluctuation is larger, cause liquid level meter probes and cable to rock, and cause the level gauging numerical fluctuations, and error is larger.In addition in some sediment levels ponds is measured, due to the settling basin bottom, rotor segment is housed, the scratch Liquid level test probe often appears, and cause measuring sonde to damage, liquid level gauge serviceable life is the longest is three months.⑵ rod-type guided wave radar material level gauge: be based on the measurement instrument of time stroke principle, radar wave moves with the light velocity, and be converted into thing position signal by electronic unit working time.Probe sends high-frequency impulse and propagates along bar, reflects by the receiver in instrument to receive when pulse runs into the thing site surface, and converts distance signal to thing position signal.Measurement result is not subjected to the impact of temperature, pressure, gas etc., and is wider in the severe environmental conditions work scope of application, almost can measure All Media, measures continuously accurately, easy to maintenance, simple to operate.But when factory measure to use, often can cause the measurement distortion because liquid level surfactant foam or impurity are attached to the feeler lever surface, affect measurement result.Therefore strict to some explained hereafter, and in the measurement of level chain system, often can cause system to stop transport or the serious consequence of liquid pool (tank) spill and leakage.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of stability that improves measurement, extends the liquid level gauge cable in serviceable life/rod-type level meter protection filtering tube device.
For addressing the above problem, cable described in the utility model/rod-type level meter is protected the filtering tube device, it is characterized in that: it comprises the joint flange of protection filtering sleeve pipe and filtering tube; The top of described protection filtering sleeve pipe is provided with described joint flange, and its bottom is provided with the measured hole that fixing level meter is popped one's head in, and its tube wall is evenly equipped with several filtering hole; Described joint flange and tank flange are complementary.
Described measurement fixed orifice is the H type.
Differ between any two 180 ° in described several filtering hole.
The utility model compared with prior art has the following advantages:
1, owing to being provided with protection filtering sleeve pipe in the utility model; this protection filtering sleeve pipe entangles liquid level gauge hawser/bar and probe from top to bottom fully; therefore; when guaranteeing that cable/bar level meter is arranged on the complicated environmental condition such as charging, dry foam, wet foam and flowable materials body; ripple component to measuring media is carried out filtering, improves the stability of measuring media, guarantees that the level meter response is sensitive; measurement result accurately, reliable, and extended liquid level gauge serviceable life.
2, owing to being provided with the filtering hole in the utility model, therefore, medium can obviously be eliminated or the filtering fluctuation by behind the filtering hole, the stability that keeps measurement, thus it is larger to eliminate the fluctuation of level gauging medium, causes liquid level meter probes and cable to rock, cause the level gauging numerical fluctuations, the problem that error is larger.
3, owing to measuring fixed orifice in the utility model, therefore, can prevent that sensor from rocking by this hole one side energy fixation of sensor (probe), can also reach on the other hand the purpose that is communicated with measuring media.
4, the utility model is simple in structure, and the level meter cable (bar) that the user can use according to reality and measuring sonde length can design processes, dismounting, install simple, easy to maintenance.

Embodiment
As shown in Figure 1, cable/rod-type level meter protection filtering tube device, it comprises the joint flange 4 of protection filtering sleeve pipe 1 and filtering tube.The top of protection filtering sleeve pipe 1 is provided with joint flange 4, and its bottom is provided with the measured hole 3 that fixing level meter is popped one's head in, and its tube wall is evenly equipped with several filtering hole 2; Joint flange 4 is complementary with tank flange 7.
Wherein: measure fixed orifice 3 and be the H type.
Differ between any two 180 ° in several filtering hole 2.
During use, protection filtering sleeve pipe 1 is packed on the tank flange 7 of tank body 6, reinstall liquid level gauge 8; protection filtering sleeve pipe 1 is entangled liquid level gauge hawser/bar 5 and probe from top to bottom fully; be screwed at last and get final product (referring to Fig. 2, in figure, 9 is the inlet opening, and 10 is apopore).
