The application of magnetic float level gauges can be said to be very wide. It has covered all industries involving level measurement processes, such as tank level metering control and drainage measurement in all industries. The side-mounted type Magnetic float level gauges are common. Although the application of the magnetic float level gauge is very wide thanks to its easy installation and a variety of materials and functions, if the installation is incorrect or the installation is flawed, it will also affect the accuracy of the measured value. Let’s talk about it below. The correct installation method of the side-mounted magnetic float level gauge and the long-distance segmented installation plan. Correct installation of side-mounted magnetic float level gauge First of all, we need to select the size of the upper and lower openings on the side of the tank and the distance between the center of the opening. The center distance between the upper and lower openings is the center distance of the side-mounted magnetic float level gauge, which is the conventional measuring range, which must be accurate. In this way, it can be installed corresponding to the opening flange of the tank during installation, and the opening size must be provided correctly.
Secondly, before installation, we need to calibrate the side-mounted magnetic float level gauge, because the shaking during transportation will cause the magnetic float inside the steel pipe to randomly string, causing the scale of the magnetic float level gauge to turn red and white. The phases are alternate, so you need to use the attached magnet to reset the scale turning column to zero before installation, and then go to the docking installation, or after installation, it is also possible to use the magnet to calibrate the turning column.
Finally, the butt joint between the flange and the tank flange must be screwed well to prevent leakage of the seal due to the failure of screwing. If the side-mounted magnetic float level gauge is equipped with remote transmission, it is also necessary to check whether the remote transmission is consistent with the zero scale and full scale of the level gauge, and whether the wiring between the remote transmission and the signal receiving device in the control room is correct and intact. Let me talk about the two options for long-distance installation. In many cases, the on-site storage tank is relatively high and the liquid level measurement range is relatively large. For example, the upper and lower measurement range is 9 meters. Sometimes in order to facilitate installation and reduce transportation costs, you generally choose to segment At this time, for the two on-site installation and measurement methods, it will be further divided into docking type segmented installation and dislocation type segmented installation. These two solutions affect the method of on-site installation.
Butt joint type segmented installation, that is, the top flange of the lower level gauge is connected with the lower end flange of the upper level gauge. After the docking installation, the middle docking section cannot see the scale because there is no flap, but the float is in the connecting pipe, which does not affect the continuous measurement.
Displacement type segmented installation, that is, two identical 4m5 side-mounted magnetic float level gauges, each level gauge has its own upper and lower flanges, the first section has a scale range of 0-4m5, and the second The scale range is 4 meters 5 to 9 meters. The scale range is continuous, but there are two level gauges with two floats, respectively in different pipes, but the effect is also continuous measurement, and the scale level flap display is not lost.
No matter which of the above methods, there is no essential difference in measurement. The difference in weiyi is that the dislocation type installation has two fewer flanges than the butt connection type.
