Product Overview
The Thermo Scientific Sarasota FD910, FD950, and FD960 liquid density
meters (collectively called “density meters” in this guide) share a common
design that provides a high accuracy density measurement of single phase
liquids and slurries. The different instrument designations relate to the
material of construction. The Sarasota FD910 is constructed of stainless
steel and designed as a general purpose sensor for use with most process
fluids. The wetted parts of the Sarasota FD950 are Hastelloy

C276. If
Hastelloy C276 and the process fluid are compatible, the improved
corrosion resistance makes the Sarasota FD950 ideal for aggressive
applications in the petrochemical, chemical, and pharmaceutical industries.
Ni-Span C

wetted parts gives the Sarasota FD960 a low temperature
coefficient, making it the ideal instrument for fiscal or custody transfer
applications.
Typical applications are listed below:

Process control

Quality control

Product interface detection

Product identification

Process monitoring
The density meters are supplied with 1” fittings. Normally, they are fitted
onto a sample bypass line, but if the pipe is small enough, they may be
fitted directly into a process plant pipeline. They are suitable for
continuous online operation in an industrial environment, and with an
environmental rating of IP65 (NEMA 4X), they are dust proof and
moisture proof.
Two versions are available. The F option provides frequency output and
4-wire PT100 connections that may be used by a remote density converter
or third-party flow computer. With the H option, an onboard HART

compliant density converter provides a linearized 4–20 mA output.
