8140 Radar Filling Level Meter

The device Type 8140 is a non-contact radar level meter for continuous level measurement. The device is available with different antennas, connection types and sizes, making it useful for a wide range of applications. The variant with integrated antenna, available with G or NPT connection, is particularly suitable for level measurement of liquids and bulk solids, especially in small tanks. The variant with plastic horn antenna, available with mounting bracket, is recommended for level measurement in open channels or streams. The variant with an encapsulated antenna system is available either with a clamp connection (DIN 32676, ISO 2852) for hygienic requirements or with a flange connection (DIN 2501/EN 1092-1). For high-temperature and high-pressure applications, a device with a metal horn antenna is also available. The excellent focus of the radar signal and the high measurement dynamics allow excellent measurement results even in small, narrow and high containers, as the risk of signal interference by installations, constructions and vessel walls is significantly reduced. Signal damping, e.g. due to signal length, foaming or low dielectric constant values of liquids, become much less important.
