UltraTWIN sends a transmit pulse to the transducer(s), which emits an ultrasonic pulse perpendicular to the transducer face, and the returned echo is sent back to the UltraTWIN. The time taken to receive the echo is measured and the distance from the transducer face to the surface being monitored is calculated.

ULTRATWIN (UL) INSTRUCTION MANUAL CHAPTER 3 HOW TO USE YOUR ULTRATWIN Operating the Controls Display On the wall mount model, there are two identical displays, by default, the top display will provide information on the current mode of operation, and status of the remote communication for point 1 (transducer 1), while the bottom display provides the same information for point 2 (transducer 2).
Page 33
PULSAR MEASUREMENT Run Mode Program Mode Test Mode 100% 000.000 XXXXXXXXXXXX REMOTE COMMUNICATOR OFF 1. Displays the current mode of operation. 2. Main 6-digit display: Run Mode; current measurement displayed, dependent on mode and measurement units chosen, and value of hotkey selected.
All modes are now described. Run Mode This mode is used once the UltraTWIN has been set up in program mode. It is also the default mode that the unit reverts to when it resumes operation after a power failure.
PULSAR MEASUREMENT How to Access Program Mode To enter program mode on the UltraTWIN, you simply enter the passcode, via the keypad, followed by the ENTER key. The default passcode is 1997, so you would press the following: ENTER Important Information There is a time-out period of 15 minutes when in program mode.
Run Mode. Pressing the hot key once will display the first parameter, then repeated pressing will display the others, then the UltraTWIN reverts to Run Mode. In program mode, they have different functions, the functions are shown below.
1) Used to confirm each action (e.g. select a menu option) ENTER 2) Used to confirm questions asked by the UltraTWIN, such as before restring factory defaults. Used to navigate up a level in the menu system, and back to run mode.
Main Menu The main or top menu is common to both points of measurement and when you first access the program mode your UltraTWIN will display the menu system for point 1. To change form one point to point 2 menu system, press the hot key, whilst in any Main Menu heading, e.g.
When you have finished, press CANCEL to go back to the previous level. When you have reached the top level, then the UltraTWIN will ask for confirmation before allowing you to go back into run mode. This is done by pressing ENTER at the display prompt.
ULTRATWIN (UL) INSTRUCTION MANUAL Once a parameter has been changed, press ‘ENTER’ and you will see the message “Saved!”. If you press ‘CANCEL’, then the change you made will not be saved, and the message “Unchanged!!” will be displayed. You can jump straight to the last parameter you edited, by pressing ‘+/-’...
To log off, send the command /ACCESS:OFF To read a parameter value, send the command /Pxxx where xxx is the parameter you wish to read, and the UltraTWIN will respond with the parameter value. To set a parameter, send the command /Pxxx:yy where xxx is the parameter number, and yy is the value you wish to set it to.

About Digital Inputs The digital inputs are used to provide the UltraTWIN with information on the operational status and condition of pumps, valves, and other process control devices. Based on the information supplied, by the inputs, the UltraTWIN, will make intelligent decisions and modify its control regime to meet the demand of the prevailing operational requirements.
