Dwyer UTS - Manual (Page 19)

Leopold-Lagco Flume
(Type 8)
Chapter 5: Additional Features
This chapter describes the functions available in Series UT’s additional menu.
The additional menu functions enable you to calibrate UT to perform the following
tasks:
• Present scanning results in volume format
• Present scanning results as a total accumulative value for flow
• Present scanning results as an accumulative sum for diameter
• Calculate volume for different tank types
• Calculate flow measurements for custom flumes
• Calculate results in alternative measurement units
• Adjust results when there is interference from a conical tank ending
• Allow compensation of different types of gas.

Chapter 6: Troubleshooting Series UT
This chapter describes the error messages displayed when an illegal value is
entered for a Series UT function, or when an option is selected that is not
applicable for the specific Series UT model you are using. If an illegal value is
entered, the appropriate error message is displayed flashing while the level of the
tank graphic on the bottom right of the screen moves up from 0 to 100%. The
numerical area then displays , enabling you to enter a new value for
the function. If an illegal option is selected, an error message is displayed while
the tank graphic fills, and the display then reverts to the menu selection.
The possible error messages are as follows:
22 mA/3.7 mA Signal Error Messages
The following list of messages will appear on the display and coincides with a 22
mA or 3.7 mA (depends on your set-up) analog current error output signal (the
default is set to 22 mA):

Error Description
The value entered is greater than the maximum
permitted value.
The value entered is less than the minimum
permitted value.
The Close value entered for a relay is greater
than the Open value entered for the relay.
The value entered for 4 mA is equal to the value
entered for 20 mA.
The selected function/option is not applicable for
the Series UT model in use.
The value entered for the 20 mA, 4 mA or Relay
function is greater than the tank height.
The value entered for the tank height is greater
than the maximum value supported by the Series
UT model in use.
The measurement unit selected is not applicable
for the Series UT model in use.
The Open value entered for the relay is greater
than the Close value entered for the relay (in
Distance mode).
A strapping table was not entered under volume
mode or a flume/weir type was not entered under
flow mode.
The value entered for the tank height is smaller
than the actual height, as measured by Series UT.
If displayed at the base of the display screen, this
indicates a problem with the current procedure, for
example, acoustic interference.
Error Description
Tank is empty or echo is lost
The sensor is located near the dead zone
