An electrode type liquid level gauge

Abstract

The invention belongs to the technical field of liquid level monitoring of conductive liquid and particularly relates to an electrode type content gauge. A central electrode is commonly used by different measurement point electrodes of a sensor, and wave-resistant pipes are additionally arranged at the central electrode and the measurement point electrodes, are carved with action indication linesand are respectively corresponding to internal measurement point electrodes; the upper end of the central electrode is welded to an upper end cover, and the lower end of the central electrode is locked with the wave-resistant pipes; the measurement point electrodes are assembled to an adjustable base, and the adjustable base is fixed on the central electrode through a jackscrew; a lead of the central electrode is pressed and connected to the central electrode, and leads of the measurement point electrodes are pressed and connected to the measurement point electrodes; the surface of the centralelectrode is coated with an anti-liquid-hanging insulating layer, and anti-liquid-hanging insulating sleeves are assembled to the outer parts of the measurement point electrodes; and output signals of the sensor are transmitted to a transmitting unit through a transmission cable. According to the electrode type content gauge, the accurate monitoring of a liquid level at any position in a storagetank can be realized; and spurious triggering phenomenon caused by the liquid surface fluctuation and splattering can be effectively eliminated.

Description

technical field [0001] The invention belongs to the technical field of liquid level monitoring of conductive liquids, and in particular relates to an electrode type liquid level gauge. Background technique [0002] In the process of industrial production and manufacturing, it is often necessary to measure and monitor the liquid level and volume of the storage tank to meet the requirements of the process and realize automatic control. At present, electrode type liquid level gauges are mainly used for conductive liquid level monitoring. Its working principle is that the probe is one electrode, and the conductive storage tank shell and threaded connector are another electrode; according to the monitoring position of the liquid level in the storage tank, the length L of the probe is determined; the electrode liquid level gauge is installed through the threaded connection On the storage tank, make the tip of the probe just at the monitoring position; when the liquid level in the...

AI Technical Summary

Problems solved by technology

[0003] At present, the general electrode liquid level gauge has the following problems: (1) The liquid level gauge is installed through a threaded connection and can only be placed outside the storage tank. Due to the limitation of the opening, it is generally located on the top of the storage tank. The liquid level at the top of the tank is difficult to monitor the liquid level below the top of the large-sized tank; (2) limited by the structure of the liquid level gauge, it is generally a single-point liquid level gauge, which can monitor three points at most, and the monitoring distance interval will not (3) Once the liquid level gauge is produced, its monitoring position cannot be adjusted on site, which cannot meet the requirements in some precise measurement occasions; (4) The electrode probe is exposed and has no structure to prevent liquid level fluctuations. When the liquid level fluctuates or splashes, it is easy to cause false signals such as misoperation or continuous operation.
