How should the flange spacing for a magnetic flap level gauge be chosen?

The selection is based on the straight section of the storage tank – for vertical tanks or horizontal tanks, the flange spacing of the magnetic flap should be slightly less than the height of that straight section; generally, a difference of around 200 mm is sufficient

First, find out the HH, H, L, and LL values for your storage tank. The bottom flange of the magnetic flap should be below the LL level, while the top flange should be above the HH level. If the height exceeds 6 meters, it will be necessary to use a two-section design or consider a magnetic flap that can be assembled in sections; in such cases, support structures may also be required in between

The flange spacing for magnetic flap level gauges is usually determined based on the specifications of the container and its installation location. When making a choice, the following aspects should be taken into consideration: 1. Ensure that the flange spacing matches the connection ports of the container. 2. Consider the measurement range of the level gauge to ensure that the flange spacing can cover the required measurement length. 3. Pay attention to the space constraints of the installation environment to ensure there is sufficient space for installation and maintenance. .

The flange spacing of a magnetic flap level gauge generally refers to the distance between the centers of the upper and lower connection flanges; this distance is also the measurement range of the level gauge. When determining the flange spacing for a magnetic flap level gauge, the following factors need to be considered: measurement range: the flange spacing should match the actual liquid level range that needs to be measured. Generally, the measurement range of magnetic flap level gauges can vary from a few hundred millimeters to several meters. Installation method: Magnetic flap level gauges can be installed either on the side or at the top. The flange spacing of a side-mounted magnetic flap level gauge refers to the distance from the center of the upper connecting flange to the center of the lower connecting flange ； The top-mounted magnetic flap level gauge has a connection flange only at its lower end to connect with the storage tank; therefore, the concept of center distance does not apply. Transportation and installation: If the measurement range is large, it may be necessary to manufacture the level gauge in sections for easier transportation and installation. At this point, it is necessary to determine the positional parameters of the support flange and consider adding one. Other factors: The properties of the medium, operating pressure, operating temperature, corrosivity, and other factors also need to be taken into account to ensure the safe and reliable operation of the level gauge. When selecting a magnetic flap level gauge, the following points also need to be taken into consideration: Medium properties: Based on the viscosity, density, corrosiveness, and other characteristics of the medium to be measured, choose the appropriate model and material for the magnetic flap level gauge. Range accuracy: Select the appropriate range and accuracy level based on the actual measurement requirements. Installation requirements: Take into account factors such as the installation location, space size, and connection method to ensure that the level gauge can be installed and used properly. Protection rating: Select an appropriate protection rating based on the requirements of the operating environment, in order to ensure the reliability and safety of the level gauge. Brand and quality: Choose well-known brands and products of reliable quality to ensure the performance and service life of the level gauge.
