Electronic liquid densimeter

Abstract

The invention relates to an electronic liquid densimeter which is characterized in that a density display instrument is connected with a weighing sensor arranged in a balance box by a cable; the weighing sensor is fixed in the balance box; the balance box can be maintained in a horizontal state when the density display instrument is positioned at any angle under the self weight and the vertical acting force of a measuring probe, so that the error of data measurement caused by the change of the level angle of the weighing sensor can be avoided; the measuring probe is connected with the weighing sensor by a measurement thread; the density display instrument can be used for calculating and displaying the liquid density according to the buoyancy and the volume of the measuring probe immersed in the liquid. The electronic liquid densimeter has the characteristics of being simple in structure, small in volume, low in cost, convenient to carry, high in measurement accuracy, etc.

Description

technical field [0001] The invention belongs to the technical field of measurement, and in particular relates to a device and a device for measuring the density of a liquid to be measured by using the volume of a measuring probe and the buoyancy it receives in the liquid to be measured. technical background [0002] With the development of modern industry, it is increasingly required to measure the density of liquid accurately and quickly in many fields of industrial production and social life. In some occasions, it is necessary to detect the density of liquid at any time and place, such as oil depots and Inventory management of oil products in industries such as gas stations. In the management of oil depots and gas stations, the density of oil products is a very important parameter. It is necessary to measure the density of oil products in real time to manage the quality of oil products and control the profit and loss in each link. [0003] At present, the liquid density m...

AI Technical Summary

Problems solved by technology

[0003] At present, the liquid density measuring equipment used at home and abroad mainly includes four types: Baume hydrometer, radioactive density meter, differential pressure density meter, and tuning fork resonant density meter. Due to various measurement limitations, they can no longer meet the requirements of industrial measurement. need

For example: the traditional Baume hydrometer is fragile and needs to be sampled for measurement. It cannot guarantee that the temperature of the sampled liquid is consistent with the temperature of the original liquid, and it is prone to errors. The reading error of different personnel is large, and it cannot be used for remote transmission.

Due to the influence of radioactive source control, radioactive density meters are greatly restricted in actual production and will be phased out gradually

The disadvantages of the differential pressure density meter are large measurement error, damaged and high cost in complex environments

The tuning fork resonant density meter is a new density measuring instrument developed in recent years. Due to the small radiation surface and small radiation impedance of the tuning fork resonant bending vibration, it has the disadvantage of low measurement accuracy in the measurement of liquid density.
