4 Installation and Operations Manual
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.
1.2 Installation, commissioning and operation
The 7532 RTG has been designed to operate safely in accordance with current technical,
safety and EU standards. If installed incorrectly or used for applications for which it is
not intended, however, it is possible that application-related dangers may arise, e.g.
product overflow due to incorrect installation or calibration. For this reason, the
instrument must be installed, connected, operated and maintained according to the
instructions in this manual: personnel must be authorised and suitably qualified. The
manual must have been read and understood, and the instructions followed.
Modifications and repairs to the device are permissible only when they are expressly
approved in the manual.
