Safety Instructions Radar Tank Gauge 1 Safety Instructions 1.1 Designated use The Varec Model 7532 Radar Tank Gauge (RTG) is a compact radar level transmitter for the continuous, contactless measurement of liquids, pastes and sludge in stilling wells. The device can also be freely mounted outside closed metal vessels because of its operating frequency of about 6 GHz and a maximum radiated pulsed energy of 1mW (average power output 1 µW). Operation is completely harmless to humans and animals

Mounting Radar Tank Gauge 3.3.2 Engineering tips Measuring conditions • The measuring range starts at the bottom end of the stilling well. • In case of media with a low dielectric constant (groups A and B), the pipe end can be visible through the medium at low levels. In order to guarantee the required accuracy in these cases, it is recommended to position the zero-point at a distance C above the tank bottom (see Fig.). • In applications with planar or parabolic antennas, especially for media

7532 Mounting Measuring range The usable measuring range depends on the size of the antenna, the reflectivity of the medium, the mounting location, and eventual interference reflections. The following tables describe the groups of media as well as the achievable measuring range as a function of application and media group. If the dielectric constant of a medium is unknown, it is recommended to assume media group B to ensure a reliable measurement. Product class DK (εr) Examples 1) A 1.4 … 1
