TBLR, TBTH and TBTHHT cells are suitable
for installation into metallic and non metallic
pipework. The cell measurement is made on the
inside of the cell body ensuring it is virtually
unaffected by the surrounding sample or vol-
ume. The cell may be mounted in a horizontal
or vertical position and is usually installed into
a modified “T” fitting. The cell will provide a
reliable and stable reading as long as there is a
flow through the cell. Ideally the cell should be
installed into an elbow installation with the flow
entering the cell at the base opening and exit-
ing from the holes around the perimeter. This
method will provide a fast response. Alterna-
tively the cell may be installed across the flow
(not suitable for TBLR type cells or K=10.0
TBTH cells). This will provide a stable and ac-
curate measurement, but the response time will
be slower.
In most applications this will not
present a problem. These cells are also suitable
for installation into sample flow lines. These are
usually installed in a flow bypass or a sample to
waste arrangement. Sample line measurement
usually provides a slower response, but has the
advantage of allowing the cell to be removed
without disturbing the process.
