The difference between magnetostrictive level gauge and magnetic flap level gauge

Magnetostrictive liquid level gauge and magnetic flap liquid level gauge are used as liquid level gauges for measuring liquid level. They also have the advantages of convenient use, stable performance, long service life, easy installation and maintenance, etc. , water treatment, medical, electric power, papermaking, metallurgy, shipbuilding and other fields are widely used in liquid level measurement. It can be seen that the two have a lot in common. So, what are the differences between the magnetic flap level gauge and the magnetostrictive level gauge?
In general, the difference between the magnetic flap level gauge and the magnetostrictive level gauge is mainly manifested in two aspects: working principle and use function.

1. The working principle is different

1. Magnetic flap level gauge
The magnetic flap liquid level gauge is based on the principle of connector and magnetic coupling to realize real-time measurement of liquid level. When the liquid level in the measured container rises and falls, the magnetic float in the float also rises and falls, and the magnetic steel in the float drives the magnetic flip outside the float to turn 180° through magnetic coupling, and both sides of the flip are painted with different colors (usually red and white) to indicate the position of the liquid level. Generally, when the liquid level in the container rises, the flap changes from white to red, and when the liquid level in the container drops, the flap changes from red to white, and the red and white junction of the indicator is the actual height of the liquid level in the container , so as to achieve accurate measurement of liquid level.
2. Magnetostrictive level gauge
The magnetostrictive liquid level meter generates an initial pulse from the electronic circuit in the electronic warehouse. While the initial pulse is transmitted in the waveguide wire, a rotating magnetic field is generated along the direction of the waveguide wire. When the magnetic fields in The time difference between the pulses can accurately measure the measured displacement and liquid level.

2. Different functional characteristics

1. Magnetic flap level gauge
The magnetic flap liquid level gauge allows users to visually observe the real-time liquid level of the medium, but because it does not have the remote transmission function, it needs to be used together with the reed switch remote transmitter to achieve remote observation and control. Compared with other liquid level gauges, the magnetic flap liquid level gauge has a relatively simple structure, and has the characteristics of no blockage and no leakage. It can clearly and intuitively observe the liquid level in real time. It is especially suitable for liquid level in petroleum, chemical and other industrial fields. instruct.
2. Magnetostrictive level gauge
The magnetostrictive level gauge is mainly composed of three parts: electronic head, detection rod and float. The electronic head is an important component that directly measures the liquid level and stores data. It is generally equipped with a microprocessor and a temperature sensor. Since it has no on-site visual display function, the liquid level value can generally only be read through the liquid crystal head. Compared with other types of probe rods, the probe rod has the characteristics of long service life and high measurement accuracy, and is mainly used in liquid level measurement occasions that require high measurement accuracy and reliability.
