Appendix Radar Tank Gauge
98 Installation and Operations Manual
Output
The 7500 RTG is commissioned by entering an empty distance E (=zero), a full distance
F (=span), and an application parameter. The application parameter automatically
adapts the instrument to the measuring conditions. The data points “E” and “F”
correspond with 4mA and 20mA for instruments with current output. They correspond
with 0 % and 100% for digital outputs and the display module.
A linearization with max. 32 points, based on a table entered either manually or semi-
automatically, can be activated locally or remotely. This function provides a
measurement in engineering units and a linear output signal for spheres, horizontal
cylindrical tanks, and vessels with conical outlet.
11.4.2 Equipment architecture
Stand-alone
The 7500 RTG can be used for measurement in a stilling well as well as in free space.
The different instrument versions are applied as follows:
• The 7532 RTG with planar antenna is the preferred device in stilling wells ≥ 150 mm.
• The 7530 RTG with horn antenna can be used in stilling wells with a diameter
<150 mm. However, for these diameters no custody transfer approval is available.
• The 7533 RTG with parabolic antenna is preferred for free-space measurements. The
7530 RTG with horn antenna can be used as an alternative for small nozzle diameters.
• The 7531 RTG with rod antenna (PTFE) should be used for measurements of highly
aggressive media (e.g. sulphur).
• The instruments are equipped with a passive 4…20 mA output with HART protocol.
The complete measuring system consists of:
