Installation conditions for external liquid level meter measuring probes Each instrument is equipped with at least one liquid level probe and one calibration probe (the liquid level probe wire length is 10m, the calibration probe wire length is 15m, and can be customized up to 30m). The two measuring probes can be used interchangeably. Liquid level probe installation: 1. Keep as far away from the feed port as possible to avoid liquid level impact ； 2. Avoid installation in places where impurities are easy to deposit, which may affect the measurement signal. ； 3. There should be no obstructions such as baffles and leaky plates within 150mm of the vertical direction of the measuring probe to hinder the measurement signal. ； 4. The calibration probe spherical tank is generally installed at the equatorial position, the vertical tank is 1.5m away from the bottom of the tank, and the horizontal tank is at the radius position. Measuring probe wiring: 1. The measuring probe cable is a coaxial shielded cable, the core wire is the positive pole, and the shielding layer is the negative pole. ； 2. After the wiring is completed, in principle it is recommended not to cut off the excess cables to facilitate future maintenance. Host installation: 2-inch riser, recommended height 1.2m. Or instrument protection box, recommended size H800×W600×L500mm for pipeline laying: Under the premise of meeting explosion-proof requirements, waterproof measures must be taken. Prevent water in the pipeline from causing water to enter the host computer and measuring probe. basic tools: Sandpaper or electric sanding tool, Phillips screwdriver, small adjustable wrench. How to choose the installation location of external liquid level gauge? 1. For a horizontal tank, observe whether the foundation heights at both ends of the horizontal tank are level. If the heights at both ends are not equal, the position of the liquid level probe should be determined at the high end. If the process situation is that liquid is inlet from the top and liquid is out from the bottom (common), the installation position of the liquid level probe should be selected at the end far away from the liquid inlet. If it is a process situation where liquid is inlet from the top and liquid is out from the top, the installation position of the liquid level probe should be selected near the lower end of the liquid inlet (less sediment). There should be no transverse partitions, leaky plates, or heat exchange pipes inside the tank corresponding to the installation position of the measuring probe (liquid level probe, calibration probe). 2. The liquid level probe of the spherical tank should be located far away from the feed port. You can consider installing it on the bottom port. 3. Vertical tank
