The method is suitable for industries such as equipment installation, building engineering, mechanical assembly, bridge construction and the like.
Description
The utility model belongs to the geometric sense field of measuring techniques.
The prior art situation:
Known to me, existing communicating pipe level meter still do not have the standard approved product, but, in engineering, use comparatively extensive at present as a kind of nonstandard product.Its measuring principle mainly is made up of milscale (20), support (21), container (22), (24), connection flexible pipe (23) and liquid (25) shown in accompanying drawing three.It is the fluid connection device principle of utilizing in the hydrostatics, because not shape, the size of tubular container, to a kind of liquid, its liquid level always is maintained at the same horizontal plane.Utilize this liquid plane as the measuring basis plane, when tested B, D have relative relief △ h, utilize milscale to measure the height h of each measured point relative liquid surface respectively at 2
1, h
2Thereby, calculate the relative relief value △ h between two measured points.Adopt this measuring method, a lot of weak points are arranged.At first, operative technique requires high, and the milscale contact is difficult to control with contacting of liquid level.Secondly, owing to need erection bracket, container and support are difficult to be placed on the same measured point, the measuring point disunity, measuring error is big, its three, be prone to because of misreading the personal error that the milscale scale brings, reliability is lower.Its four, this technology is more original, labour intensity is big, efficiency of measurement is low.
The purpose of this utility model:
In view of existing communicating pipe level measurement have operative technique and require highly, measuring error is big, precision and reliability are low, labour intensity is big, the not high drawback of efficiency of measurement, this of ad hoc meter digital communicating pipe level meter.
Content of the present utility model:
A kind of communicating pipe level meter, all particular design by (1) handle, (2) air cleaner, (3) cover plate, (4) digital indicator, (5), (9) two containers, (6) medium oil, (7) supportings adjust screw, (8) be communicated with flexible pipe, (10) go up insulating support, (11) capacitor, (12) bolt, (13) lower insulation support, (14) valve, (15) circuit board, (16) packing washer, (17), (18) screw, and (19) filter cleaner cover plate constitute digital communicating pipe level meter.Wherein: capacitor plate adopts board-like pole plate or drum type brake pole plate, and in polar board surface chromium plating.Medium oil adopts transformer oil or condenser oil, two containers have measurement face and adjust screw hole so that adjustment and fixing, be communicated with flexible pipe and adopt the oil resistant rubber pipe, air cleaner adopts folder one deck filter paper in the two-layer fine metal mesh, and circuit board adopts metal screen cover, digital indicator to adopt LCD or 2ED display outward.
Digital communicating pipe level meter work:
Measuring principle is: in container I (5) and container II (9) medium oil is housed, and is communicated with being communicated with flexible pipe (8), form the fluid connection device; Capacitor (11) is fixed on lower insulation support (10), (13), is positioned in the container I (5), shown in accompanying drawing one and accompanying drawing two.During measurement, two containers are positioned over respectively on tested 2 B, the D, shown in accompanying drawing one.Be in same surface level as tested 2, then the liquid level in two containers also is in same surface level.There is a relative relief △ h as tested B, D at 2, press fluid connection device principle, initial liquid level in two containers will change, liquid level in two containers is in till the same surface level again, and the variation of this liquid side has certain functional relation according to the long-pending relative size relation of two container cross section with B, 2 relative relief △ of D h.After liquid level changed, the electric capacity C of capacitor also will change thereupon.Also just there are certain functional relation in the electric capacitance change amount △ C of capacitor and B, 2 relative relief △ of D h like this.Convert the variable quantity △ C of this electric capacity to electric signal by Circuits System,, can on digital indicator, directly read the value of △ h through computing, amplification, equivalent conversion, analog to digital conversion.
During measurement, two containers are positioned over respectively on two measured points reposefully, open valve (14) and power switch, treat that numeral gets final product reading after stable.Should note during measurement: should first valve-off (14) ability mobile containers after measurement finishes.When transporting, taking care of and using this instrument, all must not tilt.Be communicated with flexible pipe as the need lengthening, should refuel again behind the lengthening to the sign place, and rezeroing, air cleaner should regularly clean, and changes filter paper, and latch up phenomenon must not be arranged.
Advantage of the present utility model and extremely long-pending effect:
This digital communicating pipe level meter be fit to measure apart from each other point-to-point transmission whether on same surface level, be particularly suitable for these tested 2 positions special (as aloft or the centre obstruct is arranged) be not easy to use the occasion of quasi-instruments such as shop level formula level meter, electrolevel and spirit-leveling instrument and a plurality of distributed plane whether in the precision measurement of same surface level.Also be fit to than the straightness error of long guideway and the measurement of the flatness error on plane greatly.With the exception of this, have the communicating pipe level meter relatively now, it also has following advantage:
1. easy and simple to handle, needn't spend a lot of time and energy again and grasp the touch controls of milscale contact and liquid level.
2. measuring point is unified, and measuring error is little.
3. the reliability height adopts digital display, has eliminated because of misreading the personal error that number brings.
4. be convenient to measure automatically and data analysis.
5. labour intensity is low, the efficiency of measurement height.
The utility model is applicable to the relevant precision measurement engineering of equipment installation, construction work, machinery assembling and bridge construction etc.Solved in the engineering and some technical barriers to be solved.Its application and popularization will produce remarkable social benefit and economic benefit.
