Abstract
The utility model relates to a gravity type liquid level gauge for measuring the liquid level of liquid, composed of a supporting plate, a weighing sensor and a chain type poise. The gravity type liquid level gauge measures the change of the liquid level of the liquid to be measured according to the change of the buoyancy received by the chain type poise, because the weighing sensor is disengaged from the liquid to be measured, the utility model can be suitable for various environments, and because the measuring parameter is gravity, the utility model can also be used in closed containers. Compared with the traditional liquid level gauge, the gravity type liquid level gauge has the advantages of high measuring precision, strong adaptive capacity, etc.
Description
The utility model relates to the device that tank fill level is measured.
Existing liquid level instrument principle is different, and the sensor that is adopted mainly contains: capacitance type sensor, ultrasonic sensor and diffuse si piezoresistive transducer etc.The sensor is owing to itself design and technological reason, and the ubiquity precision is low, to shortcomings such as adaptive capacity to environment differences.
The purpose of this utility model is to provide a kind of precision height, the level gauging instrument that adaptive faculty is strong.
The utility model by the back up pad 1 that is positioned at closed container or non-closed container top, be positioned at the Sensitive Apparatus on the back up pad---the chain method sign indicating number of LOAD CELLS and container is formed, described chain type weights is perpendicular to the liquid level of fluid to be measured in the container, and in the immersion fluid to be measured, its upper end is surveyed the reason end with LOAD CELLS and is linked, variation according to the suffered buoyancy of chain type weights, measure the liquid level change of fluid to be measured, the electric signal of described LOAD CELLS output-response Gravity changer, the material of chain type weights and profile depend on the chemical property and the physical property of full fluid to be measured.
This device is because Sensitive Apparatus breaks away from fluid to be measured, thus can adapt to various environment, as: environment such as high temperature, corrosion.Because the parameter of surveying is a gravity, so also can use in closed container, as Sensitive Apparatus, LOAD CELLS precision (0.02%) can be than the high order of magnitude of other form sensor (0.2%) generally speaking with LOAD CELLS for this device again.Have and survey reason precision height, characteristics such as adaptive faculty is strong.
Accompanying drawing is a structural representation of the present utility model.
The utility model has used Archimedes' principle, and promptly the suffered buoyancy of object (chain type weights) in fluid to be measured equals the weight of the fluid to be measured that it discharges.In use, chain type weights 3 is sunk to fluid to be measured, when the liquid level of fluid to be measured 5 raises, chain type weights 3 suffered buoyancy increase thereupon, the gravity that is fixed on the LOAD CELLS 2 suffered chain type weights 3 on the support plate 1 will alleviate thereupon, last LOAD CELLS 2 is converted into electric signal output with the gravitational cue of being experienced, and finishes measuring process.The utility model can be used for the measurement of various liquid levels, and its container is airtight or unsealed, and what accompanying drawing was given is the enforcement illustration of closed container 4.
