Installation conditions for the measuring probes: Each instrument is equipped with at least one level probe and one calibration probe (the cable length for the level probe is 10 m, and that for the calibration probe is 15 m; a length of up to 30 m can be customized), and the two measuring probes can be used interchangeably. Installation of the level sensor: 1. It should be placed as far away from the feed inlet as possible to avoid being affected by liquid level fluctuations ； 2. Avoid installing in areas where impurities are likely to accumulate, as this can affect the measurement signal ； 3. Within a range of 150 mm in the vertical direction of the measuring probe, there should be no obstructions such as shields or partitions that could interfere with the measurement signal ； 4. The calibration probe is generally installed at the equatorial position for vertical tanks, 1.5 m above the bottom of the tank for vertical tanks, and at the radial position for horizontal tanks. Measurement probe wiring: 1. The measurement probe cable is a coaxial shielded cable, with the core wire representing the positive pole and the shielding layer representing the negative pole ； 2. After the wiring is completed, it is generally recommended not to cut off the excess cables for future maintenance. Main unit installation: 2-inch vertical pipe, recommended height of 1.2m. Or an instrument protection box; the recommended dimensions are H800×W600×L500 mm. For pipeline installation: take waterproofing measures while ensuring compliance with explosion-proof requirements. Prevent water accumulation in the pipeline from causing water to enter the main unit and the sensing probe. Basic tools: sandpaper or power sanding tool, Phillips screwdriver, small adjustable wrench. How to choose the installation location for an external level gauge? 1. For horizontal tanks, check whether the foundation heights at both ends of the tank are level; if the heights differ, the level sensor should be positioned at the higher end. In the common process where liquid enters from the top and exits from the bottom, the level sensor should be installed at the end farthest from the liquid inlet. In the case of liquid inlet at the top and liquid outlet at the top, the installation location of the level sensor should be near the lower end of the inlet (where there is less sediment). Inside the tank at the location where the measuring probe (level probe, calibration probe) is installed, there must be no horizontal partitions, leakage plates, or heat exchange pipes. https://bbs.hcbbs.com/forum.php?mod=image&aid=2316390&size=300x300&key=02364ca548ca7cb9&nocache=yes&type=fixnone° https://bbs.hcbbs.com/forum.php?mod=image&aid=2316389&size=300x300&key=8cfdc73fe7c96bdc&nocache=yes&type=fixnone2. The position of the liquid level sensor in the spherical tank should be far away from the feed inlet; it might be advisable to install it at the bottom inlet. https://bbs.hcbbs.com/forum.php?mod=image&aid=2316387&size=300x300&key=88d2ccad2bb45e64&nocache=yes&type=fixnone https://bbs.hcbbs.com/forum.php?mod=image&aid=2316388&size=300x300&key=3fb3162e8a91e3a5&nocache=yes&type=fixnone 3.
