Abstract
The utility model relates to a buoy type metering device for liquid in a vertical tank. The buoy type metering device is composed of a lever installed on the top of the vertical tank, a buoy and a buoy counterweight which are hung on the lever, a force cell, and an amplifier, a converter and a microcomputer for processing and calculating the output signals of the force cell, wherein the buoy is immersed into the liquid in the vertical tank. Since the buoy is mutually balanced with the counterweight by the lever, the force detected by the force cell is only a part of the buoyancy of the buoy; thus, the measuring accuracy can be raised and the buoy type metering device is safe in use.
Description
The utility model belongs to the liquid meausring apparatus, is a kind of device that utilizes law of buoyancy that large-scale liquid in vertical tank is measured.
Elaeometer amount in the metering of large-scale liquid in vertical tank, particularly oil tank has consequence in production management and trade.Traditional method is the height of manual measurement store oil, calculates then.This method labour intensity is big, and efficient is low.Developed gyro at present abroad and surveyed the oil refitting and put, it is to adopt buoyancy that gyrosensor will immerse the floating drum in the oil to convert the precessional evlocity of gyro vertical pivot to, converts oil to by photoelectrometer again and weighs.But the structure of gyrosensor is complicated, makes and requires height, and will use motor, and the security that therefore this device is installed on oil tank also is a problem.Chinese patent CN90201144.8 discloses a kind of floatage-type liquid weighing instrument, and it is made up of gravity sensor and floating drum, and sensor is converted to electric signal with the buoyancy of floating drum, after amplifier, transmitter are handled, imports computing machine again and carries out computing.In this device, directly hang on the gravity sensor, and floating drum itself is heavier,, is difficult to satisfy actual needs so its measuring accuracy is lower owing to floating drum.
The purpose of this utility model provides a kind of simple in structure, safe and reliable and float-type liquid in vertical tank measuring apparatus that precision is higher.
The solution that realizes the utility model purpose is: the float-type liquid in vertical tank measuring apparatus that is provided comprises that a force cell, one immerse the floating drum of storage liquid and the force cell output signal is handled amplifier, converter and microcomputer with computing.Characteristics of the present utility model are to be provided with a lever that is contained on the Storage Tank, and aforesaid force cell links to each other with lever with floating drum, and the other end of lever hangs with the floating drum counterweight.(as minimum point or peak) floating drum balances each other with the effect of counterweight to lever when setting the liquid in vertical tank face and being positioned at a certain height, and when storing the variation of liquid liquid level, the buoyancy of floating drum will change so.The variation of buoyancy to force cell, and changes electric signal into by lever transmission, handles the back through amplifier, converter then and imports computing machine and carry out computing, according to formula Q=［ (R/r)
2-1 ］ F can obtain the variation of storage liquid weight.Q-storage liquid weight in the formula, the F-float buoyancy, R, the radius of r-Storage Tank, floating drum is constant.
The utility model utilizes lever to transmit float buoyancy, and comes balance floating drum gravity with counterweight, and therefore the power that acts on the force cell is the part of float buoyancy, so just can use high-precision force cell to measure.In addition, adopt lever transmission buoyancy not only simple in structure, and fool proof, reliable.
Fig. 1 is a structure diagram of the present utility model.
Fig. 2 is the structural drawing of floating drum.
As shown in Figure 1: on the top of storage liquid Storage Tank 1, be provided with lever 2.Force cell 3 is a pulling force sensor, and it is connected on the right-hand member of lever 2; Floating drum 4 is hung on the lever right arm, and it between sensor 3 and balance pivot 5, and at the bottom of reaching jar always; Counterweight 6 hangs over the lever left end.Whole lever system is contained in the protection box 7.Generally can set when not having storage liquid in the Storage Tank, when promptly the buoyancy of floating drum was zero, counterweight 6 made lever 2 balances with floating drum 4, and sensor 3 does not stress.When Storage Tank has storage during liquid, floating drum is subjected to buoyancy, and this buoyancy is delivered on the sensor 3 by a certain percentage, and is converted to electric signal and sends into signal processing apparatus 8.Signal processing apparatus 8 mainly is made up of amplifier 9, converter 10 and microcomputer 11, and its physical circuit can adopt the disclosed circuit of aforesaid Chinese patent CN90201144.8.
Storage liquid Storage Tank, particularly Large Storage Tanks liquid Storage Tank is higher, so floating drum 4 is also longer.For the convenience on installing and making, floating drum 4 can adopt the more piece fabricated structure, each internode is for being threaded, its concrete structure is as shown in Figure 2: every joint floating drum is welded by cylindrical shell 41 and termination 42, the adjacent both ends head is the concave, convex shape, and each saves floating drum and interconnects as a whole by termination concave, convex screw thread partly.
Claims (2)
1, float-type liquid in vertical tank measuring apparatus, comprise that a force cell (3), one immerse the floating drum (4) of storage liquid and the force cell output signal is handled amplifier (9), converter (10) and microcomputer (11) with computing, it is characterized in that the lever (2) that has one to be contained on the Storage Tank, aforesaid force cell (3) links to each other with lever (2) with floating drum (4), and the other end of lever (2) hangs with floating drum counterweight (6).
2, measuring apparatus as claimed in claim 1 is characterized in that said floating drum (4) is the more piece fabricated structure, and each internode is for being threaded.
