The DHE radar level gauge features low maintenance, high performance, high precision, high reliability, and a long service life. Compared to contact-type instruments such as capacitors and weights, it has unparalleled advantages. The transmission of microwave signals is not affected by the atmosphere, so it can meet the requirements of harsh environments such as volatile gases, high temperatures, high pressures, steam, vacuum, and high dust levels during manufacturing processes. The DHE radar level gauge products manufactured by our company are suitable for harsh environments such as high temperatures, high pressures, vacuum conditions, steam, high dust levels, and volatile gases, and they can perform continuous measurement of different level heights. The DHE radar level gauges produced by our company meet or exceed the technical specifications of similar products available domestically and internationally. They are easy to install and adjust, can be used individually or in networks, and are widely applicable in industries such as metallurgy, building materials, energy, petrochemicals, water management, and grain processing. Operating instructions for the DHE radar level gauge’s waveguide: 1. Drill a balance hole with an inner diameter of 20 millimeters every 500 millimeters along the waveguide; the eccentricity of these balance holes should be within 0.5 degrees. The welding of waveguide sections together is carried out using a socket welding method; the gap is less than 1 millimeter, the eccentricity is within 1 degree, and the straightness is within 0.5:100. The inner wall of the waveguide must be smooth, without any burrs. 2. The DHE radar level gauge must be installed in a guided wave tube with an inner diameter of 102.3 millimeters and a wall thickness of 6 millimeters. The vertical deviation of the waveguide installation is less than +/−0.5 degrees. 3. The top flange of the waveguide used to install the radar should match the ANSI 4” 300LB equipment flange, and markings should be made in advance on this flange along the direction of the centerline of the waveguide’s balance hole; these markings must align with the marking holes on the instrument flange. The horizontal installation deviation of this flange is less than +/−1 degree. A reference pin is installed on the waveguide at a position about 2.5 meters away from the mounting flange. 4. A support frame should be installed at the bottom of the waveguide, with a gap of 15~30 millimeters from the waveguide, in order to reduce the impact of turbulence during feeding. A reflector plate and a calibration ring must also be installed at the bottom of the waveguide.
