SUMMIT 8800 HARDWARE DETAILS 05
5 .2 .4 Density Transducer
A densitometer or density transducer is used to measure the density of the medium during
flowing conditions. Reference source not found. for details. The density is used in calculations
and corrected for temperature and/or pressure as required in many standards.
The type of density transducer and its selection within the stream measurement is made in the
hardware section.
Densitometers can be connected to the SUMMIT 8800 via:
• Digital (Frequency)
• HART
• Analog (4-20mA)
• Serial (modbus)
In most of the cases a densitometer will be used. The SUMMIT supports models from Emerson/
Solartron 781x and Sarasota ID900 which have a frequency output. Up of two densitometers may
be used per stream.

Also a Hart or analog input may be used. In this case only one sensor can be used.
