Abstract
The utility model discloses a measuring device and particularly a device for level indication and measurement. The utility model is composed of a stainless steel pipe or other pipe made of the non-magnetic material and two annular floats which are sheathed on the stainless steel pipe. The inner diameter of each annular float is provided with a magnet in an inlaid way. The interior of the stainless steel pipe is provided with a reed switch reed pipe switch and a resistor which are connected in series, and the top of the pipe is provided with a terminal box whose interior is provided with three wiring terminals which can output two groups of resistance signals. The utility model has the advantages of simple structure, strong practicability and extremely little error. The utility model can simultaneously reflect conditions of the liquid level and the oil-water interface actually.
Description
The utility model relates to a kind of measurement mechanism, relates in particular to a kind of liquid level indication and measurement mechanism.
In existing liquid level gauge, adopted is U type pipe principle or differential pressure transporting principle more, and its structure is comparatively complicated, and can not reflect liquid level and water-oil interface simultaneously, and this just gives in the practical application and brings inconvenience.
The purpose of this utility model is to seek a kind of both simple in structure, can reflect the measurement mechanism of liquid level and water-oil interface again simultaneously.
The utility model is to realize like this, it is made up of a stainless-steel tube or other nonmagnetic substance pipe and two annular floats that are sleeved on the stainless-steel tube, all be embedded with magnet on the two annular float internal diameters, the proportion of float 1 is less than 0.7, the proportion of float 2 is provided with some dry-reed tube switch and resistance in the stainless-steel tube about 0.9, dry-reed tube switch is connected with resistance, the stainless-steel tube top is provided with a terminal box, has three binding posts to export two groups of resistance signals in the box.
The utility model is compared with conventional art, have simple in structure, practical, the advantage that error is minimum, and can reflect simultaneously the situation of liquid level and water-oil interface truly.
Fig. 1 is built-in magnetic buoyancy liquid level gauge fundamental diagram;
Fig. 2 is the cut-away view of built-in magnetic buoyancy liquid level gauge;
Fig. 3 is circuit theory diagrams;
Fig. 4 is circuit theory diagrams;
Fig. 5 is the vertical view of annular float.
Below in conjunction with accompanying drawing the utility model is described in detail as follows:
When liquid level gauge uses, liquid level gauge 6 is inserted container bottom from container 3 tops, float 1 and float 2 are enclosed within on the liquid level gauge 6, the proportion of float 1 is smaller, can float on the pasta 4, the proportion of float 2 greater than the proportion of oil less than water, so can float on the water-oil interface 5, because of on two floats ring-shaped magnet 7 being housed all.So float floats on the position, with regard to the dry-reed tube switch in the energy adhesive liquid level gauge, the switch room string has resistance, so liquid level signal becomes resistance signal output.As: adopt the input characteristics of the thermal resistance measurement series instrument of Pt100, float 1 is inhaled switch k
1, then form circuit as shown in Figure 3: R
0+ 0.39 * n ohm is the resistance value of expression liquid level, R
0Value by the decision of liquid level gauge measuring height and display gauge head, as being limited to 1 meter on the liquid level, R then
0Be 60.25 ohm, 1 centimetre of the every rising of liquid level, one 0.39 ohm the resistance of then connecting less, the resistance of one 0.39 ohm of the one centimetre of then many series connection of descending.In like manner, float 2 adhesive resistance as shown in Figure 4, R
1+ 0.39 * n ohm is the resistance value at expression interface, R
1Be 100 ohm, 1 centimetre of the every rising of liquid level, the resistance that then many series connection are one 0.39 ohm, one 0.39 ohm the resistance of then connecting less that descends 1 centimetre if terminal box 8 and regulator connect, just can show and regulate liquid level easily, if be connected, just can control discharge opeing and discharged water with controller.
