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
11

Functional Description

Ultra 4 sends a transmit pulse to the transducer, which emits an ultrasonic pulse or radar signal (dependent on transducer) perpendicular to the transducer face, and the returned echo is sent back to the Ultra 4. The time taken to receive the echo is measured and the distance from the transducer face to the surface being monitored is calculated.
Ultra 4 can measure from zero to 40m from the face of the transducer to the surface being monitored, dependent on the application chosen and transducer used.
The relays can be programmed to activate alarms, pump starters, or other control equipment. There is an isolated 4-20 mA output that can be connected to a recorder or PLC, to monitor, depending on application chosen, level, space, distance, OCM head, OCM flow or volume, independently from that shown on the display. There is an RS232 port, so that the Ultra 4 can be operated remotely by a PC or other equipment.
Ultra 4 can be programmed either by the built-in keypad (standard on all wall and fascia units), via the SD card slot or by PC via the RJ11 Serial Interface. All parameters are stored in a non-volatile memory, so are retained in the event of power interruption. A second backup copy of all parameters can also be retained in the Ultra 4 memory, in case an alternative set of parameters needs to be stored.
Four user definable relays with individual setpoints and intelligent performance logging software features ensure maximum control versatility.
The system utilises the unique DATEM software (Digital Adaptive Tracking of Echo Movement). This is a proven digital mapping technique developed especially for the Pulsar Ultra range, which gives the system unequalled
ability when identifying the “true target level” in the face of competing
echoes from pipes, pumps, or other obstructions. Coupled with the powerful, long-range abilities of the ‘all new’ dB transducer range, the Ultra 4 lives up to its reputation as the most reliable ultrasonic level measurement system available.
The Pulsar Ultra 4 ultrasonic level controllers have been designed to provide maintenance-free fit and forget performance.

Important Information
Please note that all units are supplied for safety reasons with a 20mm 1AT fuse fitted as standard. Never operate the Ultra 4 with the protective cover removed.
An external switch or circuit breaker should be installed near to the Ultra 4 to allow the supply to be removed during installation and maintenance. In addition, the relay contacts should also have a means of isolating them from the Ultra 4.
Interconnecting cables must be adequately insulated in accordance with local regulations. Strip back 30 mm of the outer insulation of the cable. Strip 5 mm of insulation from the end of each conductor. Twist all exposed strands of the conductor together. Insert the stripped conductor into the terminal block as far as it will go and tighten the terminal block screw. Ensure that all strands are firmly clamped in the terminal block and that there is no excess bare conductor showing, and no stray strands.
Important Information
If the equipment is installed or used in a manner not specified in this manual, then the protection provided by the equipment may be impaired.
27

Preparation for Operation

Before switching on, check the following:
✓ The Ultra 4 is mounted correctly and is in a ‘safe’ area. ✓ The power supply is correctly installed. ✓ If powered by AC the protective cover is fitted. ✓ The relays are connected correctly. ✓ Any controlled equipment, e.g., motors, servos & valves, are not able to
injure people or damage property.

Maintenance

There are no user serviceable parts inside Ultra 4, except the mains fuse. If you experience any problems with the unit, then please contact Pulsar Measurement for advice.
To clean the equipment, wipe with a damp cloth. Do not use any solvents on the enclosure.
Important Information
The unique DATEM software comes into operation as soon as power is applied and is designed to monitor a moving level or target with the transducer in a fixed position.
If, after any period of use, it should become necessary to move the transducer, for any reason, from its original operating position, switch off the Ultra 4, before proceeding, to prevent any undesirable updates to the DATEM trace. If after moving the transducer the reading is not as expected, please refer to Chapter 10 Troubleshooting.

CHAPTER 3 HOW TO USE YOUR ULTRA 4

Operating the Controls

There are two main operating modes for your Ultra 4, Run Mode and Program Mode. There is also a Test Mode, used for checking the set-up.

Display

The graphical display provides different levels of runtime information on the current mode of operation, and status of the remote communication. Whilst in the Run Mode the ‘Main’ screen displays the current reading or measurement and its units of measure, along with status messages with regards to the Transducer, Echo reception and Fail-Safe Mode and relay activity. Additionally, it can be programmed to display up to 5 auxiliary variables and provide status messages on alarms, pumps etc. To scroll between run mode screens (Echo, Settings, Trend, Info and Big), use the left and right arrow keys.
The ‘Echo’ screen shows the live echo trace of the point of measurement set

When in Program mode the display is used to read information using a sophisticated progressive menu system, where parameter numbers can be entered, their details viewed, and values changed to suit the application. During Test Mode, the display is used to monitor the simulated level. A bar graph is also provided which will provide a visual reading of the level, in percentage of span.

Run Mode

This mode is used once the Ultra 4 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. When the Ultra 4 is switched on for the first time, it will display, in metres, the distance from the transducer face to the target. All relays by default are switched off.
After programming is complete, any relays that are set will operate when the level reaches the relevant setpoint, and the small square box will become solid. The letter in the box indicates the relay type.

There are two means of editing parameters in the Ultra 4, using the menu system or directly accessing them. Each means of parameter editing is now explained.

Using the Menu System

The menu system has been designed to make the changing of parameters very simple. There are two levels of menu: Main Menu and Sub Menu.
At the top of the display, there is a line of text that displays the main menu system. Pressing the left and right arrow keys scrolls the display between the top-level menu items, (as shown below).
*This option becomes available when Ultra Wizard = Level/Volume. +This option becomes available when Ultra Wizard = Flow. As you press the cursor keys to scroll left and right between these, you can
press ENTER or the down arrow at any time, to expand the sub menu. Each of these options, along with their sub-menus, are described later in this manual. When you move down into the sub-menu, you can scroll around using the arrow keys, press ENTER to go to the required section of parameters.
A scroll bar is shown where more options are available.

Once you have reached the relevant section, scroll through the parameters, and enter the necessary information. To enter the information, use the
numeric keys and then press ENTER, you will then see the message “Saved!”
If you press CANCEL, then the change you made will not be saved, and you will exit from the parameter to the menu options.
When you have finished, press CANCEL to go back to the previous level. When you have reached the top level, then the Ultra 4 will ask for confirmation before allowing you to go back into run mode. This is done by pressing ENTER at the display prompt ‘Run Mode?’

Directly Editing Parameters

If you already know the number of the parameter, that you wish to look at or edit, simply type the number in at any time while you are in the menu system. Thus, if you are in either the menu or sub-menu level by pressing a numeric key, you can enter the parameter number directly and jump straight there. You cannot type a parameter number whilst at parameter level, only at one of the two menu levels.
When you are at a parameter, the text line rotates automatically displaying the parameter name, number, the applicable units, and the maximum and minimum figure you can enter. The top line shows the value you are setting.
Once you have accessed a parameter, you can either just look at it, or change it.
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.
43

Test Mode

Test mode is used to simulate the application and confirm that all parameters and relay setpoints have been entered as expected. During simulation, there is a choice of whether the relays will change state (hard simulation) or not (soft simulation), but the relay boxes will always change colour as programmed (solid black fill or white fill), and the mA output will change in accordance with the chosen mode of operation. If you wish to test the logic of the system to which the relays are connected, select hard
simulation, but if you don’t wish to change the relay state, then select a soft simulation.
There are two simulation modes, automatic and manual. Automatic simulation will move the level up and down between empty level or the pre­determined Start Level (P983) and Pump/Control relay switch points, if you wish to change the direction of the level movement e.g. to go beyond relay setpoints, this can be done by using the arrow keys. In manual simulation, using the arrow keys will allow you to move the level up and down as required.
To enter simulation, first go to program mode. Using the menu system, select menu item ‘Test’, then sub-menu item ‘Simulation’. Simply change the value of the parameter P980 to one of the following:
1= Manual soft simulation 2= Automatic soft simulation 3= Manual hard simulation 4= Automatic hard simulation
To return to program mode press CANCEL, and test mode will end. When in manual simulation, by default test mode will move the level by
0.1m steps. Altering the increment (P981) will change this value. In automatic mode, the rate at which the level moves up and down is set by
the increment (P981) in metres, the rate (P982) in minutes, which can be changed to make the level move up and down faster. E.g., if increment (P981) is set for 0.1m and rate (P982) is set to 1 min then the level will increase or decrease at a rate of 0.1m/min. To make the simulated level move slower, decrease the value in increment (P981) or increase the value in rate (P982). To make the simulated level move faster, increase the value in increment (P981) or decrease the value in rate (P982).
ULTRA 4 INSTRUCTION MANUAL
44

Using the Serial Interface

The RS232 serial interface is used to communicate between the Ultra 4 and a PC using the optional Ultra PC and other associated Pulsar software packages, to obtain information such as data logging and view echo traces upload, download and save parameter files. In addition, it can also be used to control or obtain information using a standard PC or other computer base equipment. To do so, the settings for control are as follows: baud rate 19,200, 8 data bits, no parity, 1 stop bit.
The device should be connected as shown in Chapter 2 Ultra 4 Installation. To use the device remotely, you need to log on to start, and log off when
finished. When logged on, Ultra 4 will show ‘Remote ON’ on the display, and “Communicator OFF” when logged off.
All commands should be followed by a carriage return. When logged on, the unit will respond either OK (or a value) if the command is accepted, or NO if it is not.
To log on, send the command /ACCESS:pppp where pppp is the passcode (P922). 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 Ultra 4 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.
45
Other commands you can use are:
/DISTANCE (shows current distance)
/LEVEL (shows current level)
/SPACE (shows current space)
/RATE (shows current rate)
/VOLUME (shows current volume)
/TEMP (shows current temperature)
/CURRENTOUT1 (show the mA output 1 value)
/CURRENTOUT2 (show the mA output 2 value)
/BACKUP1 (take backup of parameters to area 1)
/BACKUP2 (take backup of parameters to area 2)
/RESTORE1 (restore parameters from area 1)
/RESTORE2 (restore parameters from area 2)
Please consult Pulsar Measurement or contact your local Pulsar representative for further details and a full list of available commands.
ULTRA 4 INSTRUCTION MANUAL
46

Parameter Defaults

When you first switch the Ultra 4 on, it will be reading the distance from the face of the transducer to the surface. It will be indicating in metres, as shown on the display. All relays are set OFF.
The date (P931) and time (P932) in the Ultra 4 were set at the factory, but may need checking, and amending if, for example the application is in a time zone other than GMT, see relevant parameter listing for full details.
In some applications, it is easier to empty the vessel, take a reading from the Ultra 4 for distance and then setup the empty level to this figure.
Once you are satisfied with the installation, and Ultra 4 is reading what you would expect in terms of distance from the face of the transducer to the material level, then you can proceed with programming, for the intended application. It is sensible to program all the required parameters at the same time. The system will be then set-up.
The span is automatically calculated from the empty level, so the empty level should be entered first.
Factory Defaults
When first installing the Ultra 4, or subsequently moving or using the unit on a new application, before proceeding to program the unit for its intended application it is recommended that you ensure that all parameters are at their default values by completing a Factory Default P930, as described in the relevant unit type parameter guide.

Example 1 Level Monitoring with Alarms

A vessel, containing liquid that has a variation in level that is to be monitored, with a high-level alarm set on Relay 1 and low-level alarm set on Relay 2.
In this example, when the level rises to 2.38m (7.8 ft), relay 1 will come on until the level drops to 2.24m (7.34 ft) when it will turn off. If the level drops to 0.28m (0.92 ft), then relay 2 will come on until it rises 0.42m (1.37 ft) when it will turn off.
The display will show the level in the tank.
The mA output will be representative of level where 4mA = empty level (0%) and 20mA = 2.8m (9.18 ft) (100%).

Example 2 Level Monitoring and Control (up or down)

A vessel, containing a liquid that has a variation in level that is to be monitored, and when the level reaches a specific point, the vessel is pumped down, with the fluid being transferred to another process. The pump will be assigned to Relay 1 a High Alarm to Relay 2 and Low Alarm to Relay 3.
In this example, there is a control relay (relay 1), which will come on if the level rises to 2.24m (7.80 ft) and go off when the level drops to 0.56m (1.83 ft) (control down). If the level rises to 2.38m (7.80 ft), then the high-level alarm (relay 2) will come on until the level drops to 2.24m (7.34 ft). If the level falls to 0.28m (0.918 ft), then the low-level alarm (relay 3) will come on until the level rises to 0.42m (1.37 ft).
Alternatively, if it is a control up application, then the on and off points for the control relay are reversed, so the control device comes on when the level is at 0.56m (1.83 ft) and goes off when it rises to 2.24m (7.34 ft). The display will show the level in the tank and the mA output will be representative of level where 4mA = empty level (0%) and 20mA = 2.8m (9.18 ft) (100%).

Example 3 Volume Application

A cylindrical tank with a diameter of 2m and a flat base that is typically used to temporarily hold liquid, and you wish to know the volume of liquid. You also require a high and low alarm and when the level reaches a specific point, the vessel is pumped down, with the fluid being transferred to another process.
In this example, there is a pump (relay 1), which will come on if the level rises to 2.24m (7.39 ft) and go off when the level drops to 0.56m (1.83 ft). (Control down). If the level rises to 2.38m (7.8 ft), then the high-level alarm (relay 2) will come on until the level drops to 2.24m (7.39 ft). If the level falls to 0.28m (0.91 ft), then the low-level alarm (relay 3) will come on until the level rises to 0.42m (1.37 ft).
The display will show the volume of fluid in the tank and the mA output will be representative of Volume where 4mA = empty (0%) and 20mA = Max Volume (100%).

Example 5 Sump Control (pump down)

A sump is typically used to temporarily hold water or effluent, and when the level reaches a specific point, the sump is pumped down, with the fluid being transferred to another process.
A sump is typically used to temporarily hold water or effluent, and when the level reaches a specific point, the sump is then pumped down, with the fluid being transferred to another process. In this example, there are two pumps, which will be set to alternate duty assist, so they come on alternately. Pump 1 is to be set to relay 1, pump 2 to relay 2, and the high-level alarm to relay 3.
This will operate as follows. During normal operation, pump 1 will come on at 1.4m (4.59 ft) and pump down to 0.56m (1.83 ft). The setpoints are then shifted to pump 2, which will come on first next time the pumps are called to run. During peak periods, when pump 1 cannot cope, pump 1 will come on at 1.4m (4.59 ft), pump 2 will come on at 1.96m (6.43 ft) and pump down to 0.56m (1.83 ft). The setpoints are then shifted to pump 2, which will come on first next time.

If neither pump can cope, and the level rises to 2.38m (7.8 ft), then the alarm relay (relay 3) will come on and go off when the level falls to 2.24m (7.34 ft). This will indicate insufficient capacity of the pumps. The display will show the level in the sump and the mA output will be representative of level where 4mA = empty level (0%) and 20mA = 2.8m (9.18 ft) (100%).

Example 6 Reservoir Control (pump up)

A reservoir is typically used to temporarily hold liquid, and when the level reaches a specific low point, the reservoir is pumped up.
In this example, there are two pumps, which will be set to alternate duty assist, so they come on alternately. Pump 1 is to be set to relay 2, pump 2 to relay 3, and the low-level alarm to relay 1. This will operate as follows: During normal operation, pump 1 will come on at 1.4m (4.59 ft) and pump up to 2.24m (7.34 ft). The setpoints are then shifted to pump 2, which will come on first next time.
During peak periods, when pump 1 cannot cope, pump 1 will come on at
1.4m (4.59 ft) and pump 2 will come on at 0.84m (2.75 ft) and pump up to
2.24m (7.34 ft). The setpoints are then shifted to pump 2, which will come on first next time. If both pumps cannot cope, and the level drops to
0.28m (0.91 ft), then the alarm relay (relay 1) will come on and go off when the level rises to 0.42m (1.37 ft). This will indicate insufficient capacity of the pumps. The display will show the level in the sump and the mA output will

Choose Your Application

There are five categories of Primary Measuring Device, which are all described in this chapter. They are exponential, BS3860 flumes, BS3860 weirs, special and universal. Calculations for flow can be performed using absolute or ratiometric calculations. The answer will be the same, the choice of calculation method being limited to the amount of information available, with regards to the primary measuring device. For ratiometric calculation it is normally sufficient to know the maximum flow at maximum head for the device in question. All types of primary measuring devices can be set up with a choice of alarms.
If you want to set-up a basic exponential device, as described in the following example 1, then choose 1. You then need to select the primary
measuring device for your application from the following available options: suppressed rectangular weir, Cipolletti (trapezoidal) weir, Venturi flume, Parshall flume, Leopold Lagco flume, V notch weir or other, for
any other type of exponential device. To set-up an application for a BS3680 flume, as described in the following
example 2, then choose 2. You then need to select the primary measuring device for your application from the following available options: rectangular flume with or without hump, U-throated flume with or without hump.
To set-up an application for a BS3680 weir, as described in the following example 3, then choose 3. You then need to select the primary measuring device for your application from the following available options: rectangular weir, V notch full 90o (90degrees), V notch half 90o (53 degree 8 minutes) or a V notch quarter 90o (28 degree 4 minutes).
To set-up an application for a device contained in special, choose 5. You then need to select the primary measuring device for your application from the following available options: Palmer Bowlus flume, H-flume or a V notch, other than BS3680.
77
For devices, which do not match any of the above devices the application can be setup using a universal flow calculation, to select this option choose 6. You then need to select the primary measuring device for your application from the following available options: linear flow or curved flow. Once you have chosen your application you will be asked a series of questions which are answered by choosing the appropriate option as detailed in the flow chart below. Once all the questions have been answered you will be prompted to provide further information, as detailed in the tables below, to complete the programming of the unit.

Example 3 BS3680 Rectangular Weir

In this example, it is required to calculate to the flow through a BS3680 Rectangular weir. Absolute calculation will be used, and there is a requirement for an alarm to indicate a high flow condition to be set to relay
3. The flow rate is required to be displayed in litres/minute and the totaliser is to record the flow in cubic metres, the resettable totaliser is to be displayed during RUN.
The distance from the end of the transducer horn to zero flow (P105) is 1 metre and max head (P704) is 0.4 metres, maximum flow (P705).
Approach width (Dim “A”) P710 = 0.5 m (1.64 ft) Crest width (Dim “B”) P711 = 0.3 m (0.98 ft) Crest Height (Dim “C”) P712 = 0.3 m (0.98 ft)

BS3680 Rectangular Broad Crested Weir

Point of Measurement

The transducer must be above the maximum head P704 by at least the near blanking distance P107.
The head is measured at a point 3 to 4 times the maximum head upstream from the weir crest, to ensure the surface of the liquid is not affected by turbulence or drawdown.
Important Notice
If relay setpoints do not meet the exact requirements of the application,
they can be modified to suit by pressing ENTER when, “For More Options Hit Enter”, is displayed, and entering new values to relay setpoints as
required. Alternatively, the relevant relay setpoint can be accessed either by the main menu system or directly via parameter number and changed as necessary.

Special Devices

Point of Measurement

The transducer must be above the maximum head P704 by at least the near blanking distance P107.
In the case of a Palmer Bowlus flume the point of head measurement should be half the value of Dim “A” P710 upstream of the device.
For a H-Flume the head measurement is taken at a point downstream from the flume entrance as detailed in the table below:
