Magnetic flap level gauge
2011-11-29 9:33:53

本体周围不容许有导磁物质接近,禁用铁丝固定,否则会影响磁翻板液位计的正常工作。 The magnetic flap liquid level meter body is not allowed to have magnetic conductive material around, disable iron wire fixing, otherwise it will affect the normal operation of the magnetic flap liquid level meter.
安装必须垂直,磁翻板液位计与容器引管间应装有球阀,便于检修和清洗。 The magnetic flap liquid level gauge must be installed vertically, and a ball valve should be installed between the magnetic flap liquid level gauge and the container's guide tube to facilitate maintenance and cleaning.
If users use heat tracing pipes by themselves, they must choose non-magnetic conductive materials, such as copper pipes. The heat tracing temperature is determined according to the condition of the medium.

The medium should not contain solid impurities or magnetic substances to avoid blocking the float.
Before use, the small balls below the zero position should be set to red with calibration magnets, and the other balls should be set to white.
According to the condition of the medium, the main pipe should be cleaned from time to time to remove impurities.
Open the bottom flange and install the magnetic float (Note: the heavy end with the magnetic end is up and cannot be inverted.

When debugging, first open the upper lead valve, then slowly open the lower valve to allow the medium to enter the main pipe smoothly (the medium should be prevented from impacting the float sharply during operation, causing float fluctuations and affecting display accuracy), and observing whether the magnetic red and white balls are flipped Normally, then close the lower inlet valve, open the drain valve, lower the liquid level in the main conduit, operate it three times according to this method, it is normal, and it can be put into operation (except for special liquids such as corrosive).

For liquid level gauges that exceed a certain length (ordinary type> 3 meters, anti-corrosion type> 2 meters), an intermediate reinforcement flange or earspan needs to be added as a fixed support to increase strength and overcome its own weight.
的安装位置、避免物料流体局部区域的急速变化、应避开或远离物料介质进出口处、影响液位测量的准确性。 The installation position of the magnetic flap liquid level gauge should avoid rapid changes in the local area of the material fluid, and should be avoided or kept away from the inlet and outlet of the material medium, which affects the accuracy of the liquid level measurement.
When equipped with remote transmission supporting instruments, the following items need to be done:
1 The remote transmission supporting instrument should be close to the main pipe of the level gauge and fixed with a stainless steel hoop (iron is prohibited).
2 The sensing surface on the remote transmission supporting instrument should face and close to the main duct.
3 The zero position of the remote supporting instrument should be on the same horizontal line as the zero indication of the level gauge.
4 The connection between the remote transmission supporting instrument and the display instrument or industrial control computer should be laid through a protective tube alone or with a shielded two-core cable.
5 After laying the terminal box's wire entry hole, it is required to be well sealed to prevent rainwater, moisture and other intrusions to prevent the remote transmission supporting instruments from working properly. The terminal box should be covered in time after the maintenance or debugging is completed ...
