TD-107 Oil Content Monitor
Operation Manual
The unit should not be installed:
•
Adjacent to known heat sources or in
direct sunlight; this could cause the
internal temperature of the unit to be
significantly higher than ambient
temperature and produce errors or
damage the components.
•
Within 10 feet [3.05 m] of devices such
as large generators or transformers,
which generate a strong electromagnetic
field—cooling water recirculating pumps
are not a problem.
The maximum environment
temperature is specified at 120
°
[49 C].

4.4 Mechanical Connections

Refer to the General Arrangement
Drawings for the location of the required
mechanical connections. The TD-107
OCM must be mounted to a vertical surface
with the mounting tabs. The mounting tabs
accept a maximum 0.375 in. [9.53 mm]
diameter bolt.
Two 0.25 in. [6.35 mm] connections are
provided for pipe hook-up.
•
Sample inlet line: 0.25 in. [6.35 mm]
FNPT. An inlet relief valve may be
added on systems where the possibility
of over pressurization exists. See
General Arrangement Drawings for
recommended installation method.
•
Sample outlet line: 0.25 in. [6.35 mm]
compression tube fitting. Spacer PN
105978 is used to prevent inadvertent
over-tightening of the NPT fitting. Over
torqueing may cause movement or
damage to the internal components of
the sample block, specifically the
internal threads, quartz flow cell, and
flow cell O-ring. The NPT fitting
maximum torque is 30 in-Ibs.
•
Optional vent connection: 0.25 in. [6.35
mm] compression tube fitting. See
General Arrangement Drawings.

instrument may occur if plumbed

4.4.2
Sample outlet from the TD-107
should be piped to either an atmospheric
drain with no back pressure or a
pressurized system. Atmospheric drains
must have the drain pipes terminate below
the unit. Pressurized system discharge must
create sufficient pressure drops to create
flow through the instrument. Do not combine
the discharge from other devices to the TD-
5.0
107 OCM discharge.

The outlet plumbing connections
MUST NOT place stress on the
0.25 in. [6.35 mm] tube drain
Pipe rises greater than 10 ft [3.05 m]
should be avoided. In installations
where this is not feasible, contact
Mounting the unit at eye level is
recommended.
Flow Rates and Tubing
Higher flow rates may require more
frequent cleaning of the sample cell.
