New FMCW radar for liquids, slurries and pastes
A radar signal is generated via an antenna and transmitted down the vessel or tank which is then reflected by the target surface and received back at the antenna.
The VG5 FMCW radar uses a high frequency signal, nominal 10Ghz which increases linearly during the measurement (frequency sweep). The signal is emitted, reflected from the target surface and received at a time-delayed frequency. The difference is calculated from the actual transmit frequency and the received frequency and this difference is directly proportional to the distance measured.
The advantages of VG5 FMCW principle compared to other radar technologies are:- better reflection separation, reliable noise reduction, smaller beam angle, high signal reflection and small antenna diameter for the same measuring range.
Operators can now read the tank level measurements from ground level with the new remote display option. The device can be configured without having to climb to the top of the tank. This saves time, reduces maintenance and reduces the risk of slips, trips and falls from height.
The remote converter can be installed up to 100m/328ft away from the process connection on the tank. The remote housing can be attached to a wall, pipe or rigid surface with the supplied wall support mounting bracket.
