Suspending hammer weighing type liquid level gauge

Abstract

The invention discloses a suspending hammer weighing type liquid level gauge featured with simple structure, reliable operation and low cost and applicable to all operating conditions. The structure is as follows: a suspending hammer (2) is a column-shaped part provided with uniform upper and lower cross sections and immersed in detected liquid (4), the suspending hammer is hung in a container (1), the lower end of a connecting rod (5) is fixedly connected with the upper end of the suspending hammer (2), the upper end of the connecting rod (5) is fixedly connected with the lower end of a hanging type weighing sensor (6), and the upper end of the hanging type weighing sensor (6) is fixed. The hanging type weighing sensor (6) is electrically connected with a singlechip (15) through an electric cable (9), the singlechip (15) is electrically connected with a display screen (11), and the singlechip (15) is electrically connected with a key switch (12).

Description

[0001] Technical field: [0002] The invention relates to a liquid level gauge, which is a low-cost liquid level gauge with wide adaptability. [0003] Background technique: [0004] The current liquid level gauges include float type, pressure type, infrared type, ultrasonic type, laser type, radar type, nuclear radiation type and so on. But none of them can adapt to all working conditions: the floating ball type is purely mechanically controlled, and it is difficult to adapt to the needs of automatic control; the pressure type cannot adapt to sewage, and it will fail immediately once the sampling point is blocked; the infrared type, ultrasonic type and laser type cannot adapt Water vapor and boiling water cannot be used, and hot water scaling also affects the accuracy of measurement; although radar and nuclear radiation types can adapt to water vapor, nuclear radiation types have radiation, and personnel cannot approach them. In addition, this measurement method is expensive. ...

But none of them can adapt to all working conditions: the floating ball type is purely mechanically controlled, and it is difficult to adapt to the needs of automatic control; the pressure type cannot adapt to sewage, and it will fail immediately once the sampling point is blocked; the infrared type, ultrasonic type and laser type cannot adapt Water vapor and boiling water cannot be used, and hot water scaling also affects the accuracy of measurement; although radar and nuclear radiation types can adapt to water vapor, nuclear radiation types have radiation, and personnel cannot approach them. In addition, this measurement method is expensive.

The most difficult thing to measure is that there is a large amount of foam on the liquid surface. Except for the float type and pressure type, other methods cannot accurately measure the liquid level.
