1. Installation guidelines: Ensure that the cable or rod does not come into contact with any internal obstacles throughout its entire range of motion. Therefore, during installation, it is advisable to avoid any equipment inside the tank as much as possible, such as ladders, limit switches, heating devices, supports, etc. It should also be noted that the cable or rod must not intersect with the feed stream. II. When installing the instrument, it is also important to note that the maximum material level must not fall within the measurement blind zone ； The instrument must be kept at a certain distance from the tank wall ； When installing the instrument, try to align the cable or rod so that its direction is perpendicular to the surface of the medium being measured. Instruments installed in explosion-proof areas must comply with the **installation regulations for explosion-hazardous areas. The intrinsically safe enclosure is made of aluminum. Inventive safety instrument enclosures are installed in areas with explosion protection requirements, and the instruments must be grounded. The following installation guide applies to cable-type and rod-type measurements of solid powders or liquids. III. Installation location: Keep it as far away as possible from the discharge port and feed port. The metal can does not touch the can walls or bottom throughout the entire range. It is recommended to install it at a distance equal to 1/4 or 1/6 of the hopper’s diameter from the tank wall, with a minimum distance from the tank wall equal to 1/10 of the measurement range. The minimum distance between the cable or rod probe and the tank wall shall be ≥300 mm. The bottom of the probe should be at a distance of ≥30 mm from the bottom of the tank. The minimum distance from the probe to any obstacles inside the tank is ≥200mm. If the bottom of the container is conical, it can be installed at the center of the tank top. https://p3-sign.toutiaoimg.com/tos-cn-i-qvj2lq49k0/6406dbe785fb4d0fa6226838abbf70f0~noop.image?_iz=58558&from=article.pc_detail&x-expires=1687314246&x-signature=ncayvkNSS50xmIsPhBmZfEQ8mQw%3D IV. Installation Method 1. Proper installation ensures the instrument’s long-term reliable and accurate measurement: The guided wave radar level gauge can be connected via threading; the length of the threads should not exceed 15 mm. It can also be installed on a short pipe. For installation of stub pipes with diameters ranging from 2″ to 6″, the height of the stub pipe should be ≤100 mm. (The shorter the length of both the threads and the stub pipe, the more stable the measurement.) If the stub pipe is relatively long, it is advisable to cut it down to a shorter length; alternatively, fix the cable-type probe at the bottom and use an insulated centering bracket to prevent the probe from coming into contact with the end of the stub pipe. 2. Installation inside a short pipe of DN200 or DN250: When the guided-wave radar needs to be installed in a short pipe with a diameter greater than 200 mm, echoes are generated on the inner wall of the short pipe, which can cause measurement errors when the dielectric constant of the medium is low. Therefore, for a short pipe with a diameter of 200 mm or 250 mm, a special flange with a “flared interface” must be selected. https://p3-sign.toutiaoimg.com/tos-cn-i-qvj2lq49k0/2570ccfe2f734628a383683e450aaa73~noop.image?_iz=58558&from=article.pc_detail&x-expires=1687314246&x-signature=GyKXC01O617pFATUOQtAdnYuCfY%3D 3. Installation precautions for plastic tanks: Whether it’s a cable-type or rod-type setup, in order for the guided wave radar to function properly, the surface of the process connection must be metallic. When the guided wave radar is installed on a plastic tank, if the tank top is also made of plastic or some other non-conductive material, the instrument requires a metal flange; if threaded connection is used, a metal plate is needed. 4. Installation of liquids with low dielectric constant: For media with a dielectric constant greater than 1.3, viscosity ≤ 500 cst, and that do not tend to adhere, guided-wave radar can be installed within guided waves for measurement. Its advantages include excellent reliability and high precision ； It can be used with any dielectric having a dielectric constant of ≥1.3; the measurement is independent of the dielectric’s conductivity ； Obstacles inside the tank and the size of short tubes do not affect the measurement. 5. Measurement of corrosive media: When measuring corrosive media, rod-type or cable-type probes equipped with PTFE or PFA sleeves can be used for this purpose. 6. Installation on horizontal and vertical tanks: https://p3-sign.toutiaoimg.com/tos-cn-i-qvj2lq49k0/b86c7c2251f349eeb8f1eea04e13dde0~noop.image?_iz=58558&from=article.pc_detail&x-expires=1687314246&x-signature=eeKrHTMawGCP9QMawNsTn3mxUKQ%3D The rod-type probe can reach a length of up to 6 meters; for tanks where the measurement distance exceeds 6 meters, a 4mm cable-type probe can be used. The installation method is the same as that for measuring in solid powder silos. The distance between the probe and the tank wall should be at least 300 mm, and it is essential to avoid any contact between the probe and the tank wall. When selecting the probe length, ensure that the bottom of the probe is at least 30 mm above the bottom of the tank. If there are many obstacles inside the tank or they are too close to the probe sensor, a guided wave tube can be used for measurement.
