Liquid level meter

Abstract

The embodiment of the invention provides a liquid level meter. The liquid level meter comprises a plurality of non-contact liquid level measurement sensors and a liquid level data output module; the non-contact liquid level measurement sensors are configured to be arranged outside a container capable of sensing the change of a measured liquid level in a parallel manner, so as to obtain a liquid level data measurement value; the liquid level data output module is configured to output the liquid level data measurement value; the distance between at least part of the non-contact liquid level measuring sensors in the plurality of non-contact liquid level measuring sensors is determined through the measuring range and the measuring precision. According to some embodiments of the invention, by virtue of a differential idea, the density of the liquid level sensor is arranged according to the measuring range and the measuring precision, so that the liquid level measuring precision and flexibility are improved.

Description

technical field [0001] The present application relates to the field of liquid level measurement, and in particular, the embodiment of the present application relates to a liquid level gauge. Background technique [0002] The liquid level gauges currently on the market can theoretically complete the continuous measurement of all possible liquid level heights within the maximum range, but are limited by factors such as the measurement environment, instrument parameter configuration, and instrument manufacturing costs. On the one hand, the measurement The accuracy is not high. On the other hand, the cost of customizing a liquid level gauge with a specific precision is high; the liquid level gauge has special requirements for the material of the liquid medium and the container, and the service life is short; the liquid level gauge of the petrochemical liquid storage tank mostly uses wired transmission Technology, through the construction of wiring, the liquid level information i...

[0002] The liquid level gauges currently on the market can theoretically complete the continuous measurement of all possible liquid level heights within the maximum range, but are limited by factors such as the measurement environment, instrument parameter configuration, and instrument manufacturing costs. On the one hand, the measurement The accuracy is not high. On the other hand, the cost of customizing a liquid level gauge with a specific precision is high; the liquid level gauge has special requirements for the material of the liquid medium and the container, and the service life is short; the liquid level gauge of the petrochemical liquid storage tank mostly uses wired transmission Technology, through the construction of wiring, the liquid level information is transmitted to the control platform. On the one hand, the wiring cost is high; on the other hand, the wiring of some liquid storage tanks is difficult and the wiring construction period is long.
