SECTION 2 ! INSTALLATION
!! CAUTION: All transducers have a directional arrow on the tag and/or
etched into a metal part. Before installing a sensor, please note proper
flow direction. This is critical to sensor operation.
!! CAUTION: If you have more than one Rheotherm unit, make sure the
complete serial number of the transducer matches the complete serial
number of the transmitter. The transducer and transmitter are a matched
set. Components with different serial numbers should not be interchanged
unless specifically ordered as spares. The transducers have no user
serviceable parts, so do not try to disassemble, as permanent damage may
The transducer style supplied with your meter is listed in the model code number in SECTION 6. Proper
installation of the sensor is necessary for achieving accuracy and repeatability. Installation suggestions
for each type of standard transducer are given here. For custom transducer installations, refer to
CUSTOM INFORMATION — SECTION 6.
Be sure wetted surfaces are clean before installing. If cleaning is needed, use non-residue solvent and
wipe dry. If the sensor has a junction box, keep moisture out. Make sure the lid is tightly sealed and,
if supplied, the gasket is in place. Seal conduit lines at the junction box if conduit lines can become wet.
TU (nonintrusive) — TU '
c transducers particularly require special care in handling
and installing to avoid damage to sensor tube stubs.
!! WARNING: TU transducers are made with thin-walled tubing — use
care when installing.
All TU transducers (other than '
c inch) should have straight line input and output
sections, typically 20 pipe diameters on the inlet and 6 to 10 diameters on the outlet. If
installed vertically, the flow should be flowing up through the sensor. Connection in the line
is via compression fittings, hose with clamp, threaded fittings or flanges, whichever is
appropriate. Care must be taken not to transmit a twisting force through the transducer's
midsection. The TU transducer, whether flanged or not, must not be used to pull other piping
together or to make up angular mismatch of fittings. The transducer junction box (if supplied)
should never be rotated for any reason.
transducers may be sleeved with a
c" tube for added support. Connection should
always be made to the '
" tube, as there is no assured seal between the '
" tube and the
