Liquidew I.S. User's Manual
d. The temperature transmitter has a 6mm diameter probe. It is suitable for
installing into the 1/8" NPT female port at the other end of the sensor
block, by using the Swagelok
6M0-1-2, 'bored-through' male connector. Follow the standard Swagelok
installation instructions to make the connection.
To install the complete Liquidew I.S. sensor assembly into the sampling system, follow
these steps:
a. Select a location to mount the sensor assembly which has suffi cient
clearance for connecting and disconnecting the inlet/outlet tubing and
cable. The surface should be strong enough to hold the analyzer.
b. Mount the Liquidew I.S. sensor assembly into the sampling system via its
two mounting holes.
NOTE: The orientation of the sensor assembly should be vertical
with the moisture sensor uppermost to minimize spillage of
sample liquid when removing the moisture sensor for calibration
maintenance.
c. Sample liquid connections are made via the process inlet and process
outlet ports as shown in Figure 7 . Both the process inlet and outlet ports
are 1/8" NPT female ports. Michell recommends using Swagelok
1/8" NPT (ordering code SS-6M0-1-2) or 1/4" to 1/8" NPT (ordering code
SS-400-1-2) male connectors to connect these two ports to the 6mm
or 1/4" sampling system tubing. Follow standard Swagelok
instructions to make the connections.
Although the operation of the Easidew PRO I.S. dew-point transmitter is not sample
fl ow-rate dependant, it is important to ensure that the fl ow velocity through the sample
line to the sampling block is high enough to avoid long time lags in response to changes
in moisture at the sample source. Michell recommends that a flow-rate of 0.1 to 0.3
l/min (0.026 to 0.079 GPM) (or equivalent at pressure) be set and that the dew-point
transmitter is mounted as close as practicably possible to the point of measurement.
