PROCEDURE FOR MAINTENANCE CHECK SHEETS
FOR THE ULTRAFLOW 150
Record the company’s name and the plant name of where the flow monitor is located. The
location can be the name of the city or the street where the plant is located. The serial number
can be found on the back of the Enhanced Remote Panel. Some Ultraflow 150’s have two TIE
boxes networked to one Enhanced Remote Panel. Record which one you are servicing. Some
Ultraflow 150’s can have both a Path A and a Path B for each TIE. If the TIE you are working on
has both, start a sheet for PATH B and the combined Path (PATH AB).
All of the data recorded can vary depending on the process and the load range of the process.
The data is best used when compared to historical records. This shows the importance of
recording the Load Level. This can be Mega Watts, Steam Load, or a Process Level.
The
SERVICE DATA screen is easily accessible from the main display by pressing the enter
button twice. Select which TIE and Path you are interested in. Fill in the “Before” section of this
table with information from the Fundamental and Advanced screens.
The
NUMERICAL DATA can be found by pressing the enter button once and then moving down
the Main Menu by using the down arrow button. Select which TIE you are interested in. There
are three screens you need to get into to obtain data. Record the Average values from the
Flow
Data , Internal Temperature Data , and External Temperature and Pressure screens. If the
Ultraflow 150 monitor does not use the External Temperature or Pressure inputs, enter NA.
The
SOFTWARE VERSIONS can easily be found by pressing the enter button once from the
Main Display and then using the down arrow to get to the Software Versions screen. Record the
values before any maintenance is done.
The
STATUS HISTORY and ALARM HISTORY screens both may contain several pages. They
can be found by pressing the enter button once from the Main display and using the down arrow
to get to the bottom of the Main Menu. Check both the Primary and an Extended Status screens
for your appropriate configuration. Any recent anomaly should be noted. The Status Codes can
be decoded with the Status Help.
The
TRANSDUCER and TIE ELECTRONICS checks are done at the measurement location.
This is typically on a stack or duct. Teledyne Monitor Labs Inc. recommends checking the purge
air filters on a monthly basis after the installation. Most sites find it necessary to replace the filters
every three months. Some sites may need to replace them more often and others may decide to
create their own maintenance schedule. The Part Number for the filter is 820202.
The transducers and mounting tubes are easy to check and clean. Undo the latches holding the
transducer assembly. Inspect the end of the transducers and gently remove any ash or other
debris. A foam insert is included in the end of some of the transducers. Its part number is 1001-
0103-01. If you have this type of transducer, it can be replaced or cleaned. The mounting tubes
should be inspected with a strong flashlight. Some buildup can occur near the end that sticks into
the effluent. This can be hard to detect since the buildup is often uniform.
Record the TIE Electronics power supply voltages. They are located on the large P.C. board in
the TIE box. Its Part Number is 1903-0100. A drawing is included to help locate the test points.
