Tilting pendulum type float ball liquid level meter

Abstract

The invention discloses a tilting pendulum type float ball liquid level meter which comprises a mounting and connecting part, a computing-controlling-displaying-communication-signal outputting part, a tilting angle measuring element, a float ball and a pendulum rod. The mounting and connecting part is used for mounting and connecting a pendulum part to a measuring position. The computing-controlling-displaying-communication-signal outputting part is mainly used for completing signal collecting, data computing, signal displaying, wireless and wired communication work of a communication device and other equipment terminals, and signal outputting work. The tilting angle measuring element is mainly used for measuring the tilting angle of the pendulum part and the horizontal or vertical direction. The float ball floats on a liquid surface, provides buoyant force and transmits liquid surface change information. The pendulum rod is fixedly connected with the float ball, provides a fixed length, and provides a determined computing parameter.

Description

technical field [0001] The invention relates to a liquid level gauge, in particular to a tilting ball float liquid level gauge. Background technique [0002] At present, liquid level gauges are widely used in various liquid level measurement fields and are very common measurement sensors. There are many technical means to realize liquid level measurement, and there are many types of liquid level gauges. Due to the characteristics of various principles, in actual use, each liquid level gauge also has its advantages and disadvantages. [0003] The magnetic coupling principle used by the magnetic float level gauge is mainly composed of a float with a built-in magnet and a plunger with a built-in reed switch. When the liquid level of the container changes, the float also moves up and down. Due to the magnetic effect, the dry spring of the float level gauge is magnetically attracted, and the position of the liquid level is changed into an electrical signal to realize liquid lev...

AI Technical Summary

Problems solved by technology

The disadvantages of the magnetic float level gauge are: low measurement accuracy; the damage of a reed switch will cause the entire device to be unable to measure, and the reliability is low; due to loss of magnetism, it cannot be measured; when the liquid is viscous, it is very easy to jam the ball, Not suitable for use in strong corrosive environment

The disadvantages are: high cost, high installation requirements, complicated debugging, high maintenance requirements, and at the same time, problems such as ball jamming and loss of magnetism will also occur

Disadvantages are: complex structure, many components, and difficult to guarantee reliability throughout the day; used in calm light non-corrosive liquids; installation and debugging are more troublesome, maintenance is complicated, and the cost is high

The disadvantage is that ultrasonic propagation is greatly affected by the density and temperature of the propagation medium, and cannot be used in harsh environments

Working conditions such as surface crystallization will also affect the use

[0010] Therefore, there is also a lack of a liquid level gauge with simple structure, low cost and simple maintenance in the market.
