Installation instructions radar – bypass

Weather protection cover • Always recommended for outside installation to avoid strong temperature changes of electronics Optimum horn size • 95mm/3.7") use the next larger antenna and adapt it mechanically

Ball valve • Measurements through an open ball valve with full passage are possible

Measuring range • Measurement is possible up to the tip of the antenna, on principle, however, the end of the measuring range should not be closer than 50mm/2" to the tip of the antenna because of corrosion and build-up formation Recommendations for the bypass • Metallic (without plastic or enamel coating) • • Constant diameter • In transitions, caused for example by ball valves or joining of individual pipe pieces, gaps of max. 1mm/0.04" are permitted
