Product Description

Corrosion Chemical Industry DN250 Magnetic Float Level Indicator


Magnetic Float Level Indicator Description

Magnetic level gauges, also referred to as magnetic level indicators, are routinely used to provide a display of liquid level in tanks and other vessels. They are often employed in tandem with magnetostrictive, guided wave radar, or other measurement means to provide a reliable local display of liquid level, as well as an electrical signal that can be transmitted to recording instrumentation or controllers.

Magnetic Float Level Indicator Working Principle
Magnetic level gauges work on the principle of communicating vessels, therefore the level in the measuring chamber will be the same as the level in the vessel. The measuring chamber is fitted with a float, which has a magnet inside. The float with magnet will float on the medium and the magnet in the float will turn the flaps of the indicating rail.

The principle of magnetic levitation water level gauge

The magnetic suspension level gauge and the container to be measured form a communicating device, so that the liquid level between the container to be measured and the measuring tube body is equal. When the float in the measuring tube of the liquid level gauge changes with the measured liquid level, the magnetic body in the float interacts with the magnetic body in the color code displayed on the display bar and reverses, so that red means there is liquid and white means no The purpose of accurately displaying the liquid level on the spot.
According to the needs of the project, the user can also be used with a magnetic control level gauge, digital display on the spot or output 4-20mA standard remote transmission electric signal to meet the needs of recorders and industrial process control. It can also be used in conjunction with magnetic control switches and proximity switches for liquid level monitoring alarms and liquid feeding equipment control.

A) When the user receives the product, he must carefully check the product to see if there is any damage during transportation and whether it is consistent with the order requirements. After checking, install it correctly in the following order.
B) Float and measuring tube are packed separately. Remove the bottom flange, make the upper part of the float upward, put the float into the measuring tube, and install the bottom flange. Then connect with the container to be measured
C) The magnetic body in the float interacts with the magnet in the color bar on the display screen, the color code is reversed, red means liquid, and white means no liquid.

Note: Handle the float carefully to avoid damage; In order not to affect the read value, all the floats in the display column must be adjusted to white before installation.


How to use magnetic level gauge
Do not allow the magnetizer to approach the body of the level gauge. If it is not close, it will directly affect the action of the level gauge. During transportation, in order to prevent damage to the airbag assembly, take the airbag assembly out of the air pipe of the main body of the level gauge before leaving the factory. After the level gauge is installed, open the smoke exhaust flange at the bottom, and then reinstall the airbag assembly to the main body. Inside the trachea. Please note that the heavier side of the balloon assembly faces upwards and cannot be turned over.

Magnetic level gauge measurement method and troubleshooting When measuring liquid, use ceiling installation or bypass pipe side installation. A liquid level indicator, a liquid level switch and a liquid level transmitter with a turning column are installed outside the magnetic liquid level gauge body. The magnetic unit is arranged inside the float, or connected to the float through the ejector rod. When the float and the magnetic unit change according to the liquid level, the magnetic color block (magnetic reversal plate) is reversed; the magnetic liquid level switch operates at the corresponding liquid level point; At the same time, the liquid level sensor outputs a standard variable resistance signal under the action of the magnetic force of the floating ball, and the resistance signal is converted into a 4-20mA current signal through a transmitter and then output.
The above is an introduction to the principle of the magnetic suspension level gauge. After reading this, I think you will know how the magnetic suspension level gauge measures. If you want to know more about the magnetic suspension level gauge, please consult Kaida's instrument.
