Float level gauge points of use

Float level gauge is widely used in liquid level, chemical industry, metallurgy, electric power, paper making, food and industrial sewage treatment and other departments. By the magnetic reed switch, precision resistors and amplification transform circuit. When the magnetic level gauge magnetic float to a certain position of the reed switch, the reed switch is closed, so that the amplifier output conversion circuit with the measured level corresponding to the current value, as the level changes, Amplifier conversion circuit level will be converted into a linear 4 ~ 20mADC signal output, in order to achieve the level of signal transmission or control.

Float level gauge use points:

1, the level gauge calibration is normal, cast and found the float in a certain position for a period of time "sucking" phenomenon. This is mainly the level gauge through the steel platform device, the gap between the plate and produced. Therefore, special attention should be paid to the clearance between the liquid level gauge pipe wall and the cutting edge of the platform through the steel platform device. Based on field experience, this distance is about 100 mm to ensure that no impact on the magnetic float.

2, on-site adjustment will find the float moving up and down not sensitive enough. This is mostly due to improper liquid level gauge caused by the device, this time to pay attention to the center of the flange can be up and down in a line, with the degree of vertical plane. Generally speaking, the best angle with the degree of not less than 87 degrees, if the bias is greater, may affect the smooth movement of the float.

3, when the level gauge cast on the spot, pay special attention to open the upper gate valve, then open the lower gate valve. This is due to the level gauge connected to the bottom of the tube is equipped with a maintenance of the float spring, otherwise, the role of large differential pressure float may cause the float gauge can not be used.

4, the use of liquid level gauge, if the output signal generated frequent disturbance or interference pulse, it is necessary to check the signal cable shield can be firmly grounded, the work of the resistance can meet the request. If the interference is still not completely eliminated, available signal isolator to deal with.

5, the level gauge put into use for a period of time, showing floats difficult to float and the float moving insensitive situation. This is fundamentally due to the presence of iron filings or other contaminants on the magnetic float. You can empty the media, and then remove the float, remove the magnetic float stained with iron or other dirt can be.

6, if for transport or other reasons led to the scene instructions for the closed glass tube rupture, you can use domestic glass tube change. But it is best to take a vacuum. Also pay attention to the vertical glass tube, so as not to affect the indicator of the instructions.

7, special attention to the use of level gauge, do not use a strong magnet in the connected tube up and down to stop the float up and down, otherwise it will lead to changes in the polarity of the magnetic float magnetization, and even make the float magnetic weakened, resulting in difficult to work properly.
