About the Ultra 4 
Ultra 4 is a brand-new concept in ultrasonic level measurement.  Within its 
memory are all the functions and settings of three different and separate 
ultrasonic devices. 
 
The Ultra 4 does not offer a multiple range of functions blended together 
which leads to complicated calibration and a compromise to the 
specification.  The Ultra 4 is the first ever system to offer the ability to 
dedicate the functionality of the unit to any of three specific duties i.e., level 
or volume measurement, pump control, or flow measurement. Diagnostic 
trace information and measurement trending can be viewed directly on the 
display of the unit itself and automatically logged to SD card. 
The benefits are many but most importantly the unit provides: 
1.  A most versatile system which can be configured quickly, to offer 
one of three separate functions within a matter of seconds.  Ideal 
for simplicity of purchase and off the shelf spares. 
2.  Ability to log vast amounts of data using the integral Micro SD 
card slot, and at a minimum of 1-minute intervals. 
3.  A totally dedicated device with the ability to perform all aspects of 
the task required i.e., no compromise in specification. 
4.  Easy to set up using Pulsars unique “Quick Set Up” Menu.  To 
calibrate the unit, first set the Ultra Wizard for the desired task, 
then refer to the relevant chapter in this manual that relates to 
your application:  
Chapter 5 for Level or Volume, 
Chapter 6 for Pump Control 
Chapter 7 for Flow
