. Description

1

Series ULTM is an ultrasonic level meter with integrated GSM cellular modem
and USB interface. Optional items include external temperature sensor and
programmable timer switch.

eries ULTM measures distance for targets such as liquid or solids.

S

easurement is continuous and does not require contact with the target. The

M

ystem can accurately measure steady or agitated target surfaces. The system can

s

lso rapidly track filling and emptying of vessels. The system measurement

a
distance spans 5.9 in (15 cm) to 26 ft (8 m). In addition to distance, the ULTM can
also measure temperature of the environment.

Series ULTM makes use of the measured distance to calculate additional

nformation such as target level and volume.

i

eries ULTM operates at an ultrasonic frequency of 75 kHz, making it perfect for

S

oisy conditions. The sensor is made of PVDF, therefore providing good chemical

n
resistance to corrosive targets.

Series ULTM may be used with 8 to 33 VDC power. The low power mode is
available for use with batteries and is supported using a Programmable Timer
Switch (PTS).

eries ULTM is equipped with a large graphic display and keypad allowing a

S

imple wizard-driven setup of the system. The keypad and display allow

s

onfiguration of many ULTM configuration parameters. Complete setup of all ULTM

c
parameters can be executed using a USB equipped PC or laptop. This method of
configuration allows for rapid cloning of multiple ULTM systems.

Series ULTM transmits measurement information to a predefined destination –

(either cellular phone or cellular PC modem) via SMS with user-programmable

eporting intervals. The system also identifies and sends an alert in boundary

r

vents such as full and empty situations. The system can also be programmed to

e

dentify or alert for rapid changes of level, indicating theft and refuel quantities. The

i
system can also transmit on/off contact state information.

This user manual is intended for users and operators of Series ULTM. The
manual covers system description, installation, operation and troubleshooting for
the Series ULTM.

Chapter 2. Physical and Electrical Installation Guidelines

his chapter is a list of guidelines for proper physical installation of the Series ULTM

T

n tanks, including electrical connections. In the final section of this chapter, there

o

s a short and concise list of instructions–the “Must-Be pamphlet”. Always ensure

i
that the Series ULTM is installed in an area that meets the stated ratings of this
product including temperature and technical specifications.

1. Physical Guidelines

• ULTM systems are installed above the target (e.g. water, fuel) being measured
and should not make contact with the target at any time. Typically, the unit is
installed on top of a tank through a hole on the roof of the
tank. In outdoor applications, the ULTM may be attached to a metal arm
extending above the target attached nearby.

• Series ULTM should be located as far as possible from vertical tank walls and
from other physical obstructions such as filling inlets. Keep a minimum gap of: 12
in (30 cm) plus 4 in (10 cm) for each 3.3 ft (1 m) of measurement range.

• For best results, place the unit away from sources of acoustic noise or
sources of vibrations.

Proper physical installation is accompanied by software setup. Setup includes

•
efining parameters such as tank height, and may include additional parameters

d

uch as Near Blocking Distance (NBD), Far Blocking Distance (FBD), False echo

s

can and more. For additional information refer to the section in Chapter 8

s
reference guide: “Application Dimensions and Constraints” (p.14).

2. Tank Fitting

eries ULTM is equipped with a 1.5˝ BSP or 1.5˝ NPT thread allowing for two fitting

S

ptions: direct fitting in a threaded flange, or fastened with a 1.5˝ BSP / 1.5˝ NPT

o

ut through a thread-free flange.

n

or outdoor installations, use a stable arm and firmly attach the sensor to the arm

F
using a through-hole and threaded nut. Alternatively, it may be possible to attach
the sensor to a threaded hole which is built-in the arm.

lways verify thread compatibility between the Series ULTM and flange or nut. Do

A

ot use excessive force when using threads. Preferably, tighten by hand only. If a

n

rench is used, grip Series ULTM at the wrench grip surfaces only (see Figure 1

w
Series ULTM parts) and exert light force.

3. Dead Zone

Refer to Chapter 8 reference guide: “Application Dimensions and Constraints”

p.14). A gap must be kept between the face of sensor and the topmost level of the

(

arget. This gap must be at least the size of the specified “dead zone”. If the target

t

evel passes the dead zone, measurements may be unpredictable. Therefore, it is

l
recommended to keep a marginal gap between the expected topmost level and the
dead zone border. In the case where the top most level is too close to the tank roof,
an extension pipe is required for the installation of the unit as described below.

Figure 4: Threaded Flange (left) Thread-Free Flange (right).

4. Extension Pipe

Refer to Chapter 8 reference guide: “Application Dimensions and Constraints”
(p.14). An extension pipe is required for installation where the top most target level
is too close to the roof of the tank. In such cases, an extension pipe is installed on
the tank and the sensor is installed on top of the extension pipe at a safe distance
from the top most level of the target. The lower border of the dead zone may fall
inside the tank as seen in the right hand side of the figure below. In this case no
further software settings are required. The lower border of the dead zone may also
fall within the extension pipe as described in the left hand side of the figure below.
In such cases, the Near Blocking Distance (NBD) should be configured in the
software.

typical structure of an extension pipe is shown in Figure 6 below. Closely follow

A

hese guidelines when using an extension pipe:

t

Internal pipe diameter should be at least 3˝ (7.62 cm) wide.

•

The diameter of the hole on the flange or tank should not be smaller than the pipe

•
diameter.

• Pipe length (measured from sensor face) should be no longer than 20˝ (50 cm).

• The pipe should not protrude into the tank.

Pipe should be exactly perpendicular to the surface of the target.

•

Sensor must be located at the center of the pipe.

•

Pipe should have a smooth interior surface.

•

The hole in the flange or tank should have a smooth edge and welding spots must

•
be avoided.

Figure 6: Possible Extension Pipe Fittings.

5. Temperature Considerations and Temperature Sensors

Also refer to Chapter 8 reference guide: “Temperature Sensors, Units and Display”
(p.17).

When using an external temperature sensor, place the sensor at a location that
best represents temperature of the air between the sensor face and the target.
Connect the sensor internally as described in the electrical connection section to
the Thermistor pins. External temperature sensors may be ordered from the
manufacturer or may be purchased independently. Use Thermistor NTC 10 K Ω 5%
(minimum), ULTM-EXT or equivalent.

When using the internal temperature sensor, avoid situations where the Series
ULTM is exposed to different thermal conditions other than its environment, such
as direct sunlight. Direct sunlight may overheat the system and cause
measurement inaccuracies, measurement variations in time, and even failure of the
system in extreme cases. If the Series ULTM is exposed to direct sunlight,
construct a local sunshade (“umbrella”) over the ULTM.

In areas of large temperature variations, take into consideration volume changes of
the target due to temperature expansion.

6.4 Connect the power cables to the appropriate terminals.
Note: The Series ULTM operates from a DC power supply of 8 to 33 VDC.
Always make sure that sufficient voltage is present on the Series ULTM power
terminals, disregarding of any voltage drop along the supply lines.

6.5 When using an external temperature sensor or ULTM-EXT, connect the

thermistor to data pins 6 and 7. *Do not wire ULTM-PTS and ULTM-EXT at the

same time.

6.6 When using an external Programmable Timer Switch ULTM-PTS, connect the

switch to pins 6 and 7.

6.7 When using a contact alert, connect short/open between pins 5 and 4 (ground).
See the section about contact alerts in the Chapter 8 reference guide.

6.8 The mini-USB port is a USB device-side supporting virtual COM ports. The port

may be used for firmware upgrades, field monitoring and remote setup. Details

about firmware upgrade are provided in the Chapter 5: Firmware Updates
(p.12).

7. Low Power Mode and Programmable/Timer Switch (PTS), ULTM-PTS

Series ULTM supports low power mode for extended external battery lifetime. This
mode of operation requires the external Programmable Timer Switch (PTS) ULTM­PTS to be connected between Series ULTM and battery.
PTS connections:

• First connect the 5-wire cable from the ULTM-PTS to Series ULTM through one

of the glands.

• Connect the Brown (+) wire to the power plus (+) on Series ULTM.

• Connect the Yellow (-) wire to the power minus (-) on Series ULTM.

• Connect the White wire to pin 6 on the electrical port panel (see Figure 7
above).

• Connect the Green wire to pin 7 on the electrical port panel.

• Connect the Blue (ground) wire to the ground port on Series ULTM.

• Then connect the 3-wire cable from the ULTM-PTS to the battery.

• Connect the Brown (+) wire to the battery plus (+).

• Connect the Yellow (-) wire to the battery minus (-).

• Connect the Blue wire to a local ground at or nearby the battery.

2. Navigation Through Menus

Series ULTM supports two menu styles that are used throughout the setup

perations and are described below. False echo scan employs a third menu style

o

nd is described in the relevant section below.

a

2.1 Sub-Menu Style

The Sub-Menu style presents a list of vertical choices. An arrow may appear on the
right hand side of the screen if additional items can be reached when scrolling
down. The scrolling is cyclic, meaning that when you reach the last (first) item, the
next step will lead you to the first (last) item. Scroll up or down, using the navigation
keys, to your selected choice and press Enter (+). This action will lead you to the
next sub-menu.
The last item in the list of choices is **back**. Select **back** to return to the
previous menu. The previous menu will be displayed such that your last selection
will appear first on the menu. For example:

fter pressing Next, ULTM will check the validity of your numerical entry. If your

A

ntry is outside the acceptable boundaries, an ILLEGAL VALUE screen will be

e

resented. You need to press any key to return to the previous screen. A default

p

alue will replace your wrong entry. If so needed, modify the numerical entry and

v
press Next again.
The top line presents the current measurement information.

.3. Menu and Sub-Menu Organization

ready for operation. Some configuration parameters should be re-configured by the
user for proper field application. ULTM can be configured by a simple PC tool.

onfiguration by PC may be used in lieu of configuring with the integral keypad and

C

isplay. PC configuration provides the user with the full set of configuration items.

d

urthermore, configuration by PC allows the user to clone fielded ULTM systems.

F
For this cloning process, the user is required to prepare one text file and download
that file into all relevant ULTM systems. Once this configuration file is prepared, the
downloading process takes a few seconds and makes redundant any manual

eypad based operation.

k

ection 2 below begins by demonstrating a sample configuration text file.

S

Section 3 handles the downloading operation. The download process involves use
of a standard Windows application – HyperTerminal. The setup of HyperTerminal is
explained in the second section, and parts of it may be skipped by those who are

lready familiar with this tool. Section 4 presents possible responses from

a

LTM–whether good or erroneous responses. Section 5 is a list of all configuration

U

tems. Section 6 provides some configuration file example.

2.2 Multi Value Commands

ome configuration items are assembled from two values or more. For example,

S

he dimensions of a vertical cylindrical tank (prefix CYLV) are height and diameter.

t

hese two values are both included with a comma between the two values. The

T
next figure illustrates the use of the comma.

2.1 A Simple Sample File

he following text file was created using Windows Notepad application and

T

emonstrates the essence of the configuration file:

d

Digest:

• The first line resets ULTM to its default values.

• The second line instructs ULTM to set its EMPTY LEVEL to a distance of 6.0
meters.

• The third line instructs ULTM to set its FULL LEVEL to a distance of 0.70 meters.

If you are unfamiliar with terms such as empty level or full level, read reference
guide section Chapter 8: “Application Dimensions and Constraints” (p.14). Next is
a slightly more complex configuration file:

Digest:

• The first line instructs ULTM to set its EMPTY LEVEL to a distance of
18 ft (5.5 m).

• The second line instructs ULTM to set its FULL LEVEL to a distance of

1.5 ft (0.45 m).

• The third line instructs ULTM to set up the destination phone number to
[phone] (10 digits only).

• The forth and last line instructs ULTM to set up SMS interval time to 1800
seconds.

• Each instruction is implemented as a specific command such as EMP or FUL.

he third line instructs ULTM to set the tank as a vertical cylindrical tank with height

T

f 4.5 meter and diameter of 3.00 meters. The last item instructs ULTM to display

o

olume results (rather then level or distance). The comma should always separate

v
between values.

3. Download Operation

3.1 General Procedure

ULTM can be configured by downloading the text configuration file from your PC
into ULTM. The previous chapter described the making of the configuration file.
This chapter describes the download procedure. The download process can be
preformed using HyperTerminal – a Microsoft
most operating systems such as Windows XP

®

standard application which is part of

®

.

Prior to using the HyperTerminal, you must connect ULTM to the PC and install a
USB-Serial driver on the PC. You can do that by following the instructions in the
Chapter 8: “USB driver installation on a PC” (p.13).

You should find out the COM port number that ULTM is using on the PC. ULTM
must be in the measurement screen during download procedure. Two PC
applications trying to access ULTM will conflict with each other. Avoid having two
such applications running at the same time.

3.2 Launching and Setting Up HyperTerminal

This section assumes you are using Windows XP

®

. Similar procedures apply to

other operating systems.

3.2.1 Go to Start Menu and then Open Programs.

3.2.2 Open Accessories, then Open Communications then Open HyperTerminal.

3.2.3 Press NO when asked about “default telnet program”.

3.2.4 When prompt for a name, choose any name and press OK.

3.2.5 In the next window “Connect to”, select the COM port that you intend to use
for ULTM. This part is described in the next figure:

Notes:

• Each line begins, and ends, with a $ sign.

• All commands are made of capital letters.

• Each command is immediately adjacent to the first $ sign.

• There is a blank between the command and the related parameter.

• There is a blank between the parameter and the ending $ sign.

• Do not forget to press Enter after the last line.

.3 Downloading a Configuration File

3

.3.1 From the HyperTerminal screen select transfer (top right side tab) and then

3

select “Send File”.

3.3.2 Browse to the directory where you stored the configuration text file (the one
you prepared in the previous section) and select that file. Double click on the

ile to transmit it.

f

.3.3 Alternatively, you can key each configuration item line by line directly from the

3

yperTerminal screen. As a quick test of this configuration, key the following

H

ommand:

c
$VAL 1 $
Watch ULTM integral display and verify that measured data is level.
Now key the following command:

VAL 2 $

$

atch ULTM integral display and verify that measured data is distance.

3.2.7 Now you should see the HyperTerminal screen:

.2.8 Select the File tab (on the top left side) and choose Properties, then Settings,

3

nd set the parameters as described below:

a

3.2.9 Now press on ASCII setup (bottom right side) and set the parameters as
described below:

4. Responses from Series ULTM

4.1 Good Response

ULTM should reply with an OK response to each configuration item:

4.2 Erroneous Responses

ULTM will reply with an ERROR or NOTE response to a wrong configuration item.
For example:

The ERROR or NOTE response will be followed by the causing item (in this case
EMP) and is accompanied by an error number (5 in this case). Possible error codes
are listed in the following table:

Error Code

1, 2
3
4
5
6
7
8
9

4.3 Communication Errors

The erroneous responses described indicate that the link between PC and ULTM
is operating fine and that the commands are of wrong nature.

Most probable cause

Configuration item is too long
$ sign is probably missing
Wrong command name or command not adjacent to $ sign
Value is exceeds upper legal limit
Value is below lower legal limit
Value is illegal
(NOTE) Command was already sent
(NOTE) Value is below minimum value and redefined to
minimum value

Especially note the “Line Delay” and the “Character Delay”, which are not the
default values of HyperTerminal.

Note: When using the USB port for local serial data monitoring (see appropriate
chapter), you should return to the default values of the screen above and
specifically uncheck “Append Line Feeds to Incoming Line Ends”. And vice verse,
if you revert to configuration of ULTM through the USB interface, make sure to set
the parameters of the screen above correctly.

If no responses are received from ULTM, or if the responses carry unfamiliar
characters, the communication link between the PC and ULTM is not performing.
In this case, you need to check the physical cabling, verify the HyperTerminal
settings and then restart this application again.

5. Reference Guide for Configuration from a PC

5.1 List of Configuration Items

The following conventions apply for the list of commands. These conventions refer
to the values allowed for each parameter.

5.1.1 Range of Number Values

Low power timer is ON: Low level sleep time of 60
minutes when the distance to target above empty­level and longer than 6 meters. High level sleep time
is 10 minutes and occurs when distance to target is
more than 3 meters, but still less than 6 meters.
ULTM will operate continuously when the distance to
target is less than 3 meters.

Note: Always verify then re-verify that your basic settings are correct including
distance to empty level, distance to full level, level or distance choice. Most wrong
readings originate from incorrect setup.

Chapter 5. Firmware Updates

1. Introduction

ULTM firmware can be upgraded in the field. The upgrade procedure takes less
than 5 minutes, but should be done carefully to avoid damage to the system. This
feature is useful for adding new features to your ULTM system and for fixing
bugs.

If you do not see the bar starting, or if the bar has stopped moving – just wait! If

Be patient!

you disconnect the ULTM while in the middle of the upgrade process, the internal
software may be impaired and may require returning to the factory. If the bar has
not started or has stopped, wait for at least 10 minutes before reconnecting and
restarting the process.

Chapter 6. Serial Data Monitoring

1. Introduction

ULTM may be monitored locally. ULTM may be configured to send information to
a PC over the USB interface and that information may be viewed with a
HyperTerminal application. This feature is useful for field monitoring and for
debugging purposes.

E) Information may be simply viewed or gathered into a text file by using the

(

ransfer/Capture Text tab of HyperTerminal. You can define this file as .txt or

T

csv. You can also define the file as txt and later rename it to .csv. A .csv file

.

an then be conveniently viewed with an excel application.

c

Other data logging programs include Log & Forward and SMS Management Center
found on the ULTM software CD. These programs use SMS messages sent directly

o a PC to organize and display data from the ULTM. This requires a PC equipped

t

ith a cellular modem and a separate SIM card. Instructions for installing and

w

unning these programs are also found on the software CD in the folder, “ULTM

r

ocuments”.

D

3. Record Format

typical record on the HyperTerminal screen or text file may appear as follows:

A

20 1.53 1.53 2 1 27.67 29.8 2 32 6 0 50 62 1.53 0.02 0 3880 0 3

A .csv file will appear as follows:

n these recordings the third column from the left is the measured data (after

I

rocessing) and the sixth column from the left is the measured temperature. Other

p
columns are internal equipment variables applicable for manufacturer debugging
purposes. Fields may change between software versions. Check with the
manufacturer about the fields in your recording.

hapter 7. USB Driver Installation on a PC

C

his chapter describes the installation of ULTM USB drivers on a PC. The driver

T
installation is required when using the PC / laptop for:

• Configuration of ULTM

• Serial monitoring

• Firmware upgrade
The drivers were tested on Windows XP

®

and Windows®7/32 bit systems.

(A) Copy the directory “ULTM Drivers XP” from the CD to your PC.
(B) Connect the PC to ULTM using a USB cable. Keep cable length to less than two

meters. Turn ULTM on (if not already powered by the USB).

(C) Follow the standard driver installation instructions on the PC. Whenever

prompted for a driver, select the location of “ULTM Drivers XP”.

(D) The following set of windows may aid you when following with the installation.

Information being sent by ULTM includes measured data such as distance and
temperature and internal system variables.

2. Installation and Operation

(A) Install the USB driver for ULTM as described in the chapter 7: “USB Driver

Installation on a PC” (p.13). You may have done so already for the “PC
Configuration Utility” or for the “Firmware Upgrade Application”. In that case,
there is no need to do it again.

(B) Connect ULTM to your PC using a USB cable terminated with a mini-USB

connector. Refrain from utilizing USB power supply alone. It is advisable to
connect a regular DC power supply to ULTM.

(C) Launch the HyperTerminal application on the PC. To do so, follow the

instructions included in Chapter 4 “Configuration with a PC” under the sub­section “Launching and Setting up HyperTerminal”.

(D) You need to enable the monitoring function using the ENDT command from the

HyperTerminal. The command may be keyed manually or sent as text

configuration file. Review the “Configuration with PC” chapter for this procedure.

The settings of HyperTerminal for configuring ULTM and for serial monitoring are
identical, except for the item “Append Line Feed”. When monitoring, you should
uncheck the “Append Line Feed” item in the ASCII setup to avoid extra lines.

When you want to halt the monitoring function, you must prepare a configuration
file with the DSDT command and send it from the HyperTerminal application. In this
case the manual procedure is not applicable because ULTM is constantly
transmitting its own monitoring data.

Choose “Continue Anyway”...

You should also check proper installation by viewing the device manager.
If the USB driver installation failed, a “?” sign may be listed at the “Ports” item. In
other cases, the driver may be listed under “Other Devices” item. In both cases,
uninstall the device and than re-install it again.

Chapter 8. Reference Guide

Application Dimensions and Constraints

A) Basic Dimensions

• Distance • Distance to full level (FULL)

• Level • Distance to empty level (EMPTY)

• Dead zone • Maximum range

• Full level • Near blocking distance (NBD)

• Empty level • Far blocking distance (FBD)

Figure 17: Application Dimensions.

These variables are shown on the following figure along with the “Fundamental
Interdependency Equation”.

15 cm=Dead Zone < NBD < Full < Empty < FBD < Maximum range=8 meter

See also the section: Interdependencies in this chapter.

Page 14

) Distance to Empty Level

B

istance to empty level is defined as the distance from the face of the sensor to the

D

ottom-most surface of the target to be measured. For typical installation in tanks,

b

he bottom-most surface is usually the floor of the tank.

t

he modem is of the quad-band GSM type and cannot be used with other cellular

T

tandards. An antenna is connected internally within the ULTM. A SIM card must be

s

nserted into ULTM. The SIM card must adhere to the instructions provided in the

i

nstallation chapter. Carefully read and comply with these instructions.

i

ULTM supports a maximum range of 26´ (8 m) and the default value for distance to
empty level is therefore 26´ (8 m). The user is cautioned however that the maximum

ractical range depends on target characteristics. Range of 26´ (8 m) may be

p

chieved with quiet liquid surface targets. As a rule of thumb, use no more than 20´

a

6 m) for solids, turbulent liquids, when the air medium is not clear, or when

(

nterferences exist. You may verify proper operation by checking whether the

i
equipment frequently enters a state of “echo search” at your maximum distance.

When ULTM enters the empty level, it will present an empty status on the display.

LTM will then exit this state when level rises at least 0.8˝ (2 cm) above the empty

U

evel.

l

C) Distance to Full Level

Distance to full level is defined as the distance from the face of the sensor to the
top-most surface of the target to be measured. The default value for distance to full
level is 5.9˝ (15 cm). This is also “dead zone” of ULTM and cannot be reduced

nder any circumstances.

u

he user is cautioned to prevent targets from crossing this limit, as this may result

T
in unpredictable measurements. You can overcome this limitation by proper
installation. For example, if the target can approach the tank roof, install ULTM on
top of an extension pipe which is at least 5.9˝ (15 cm) long.

hen ULTM enters the full level, it will present a full status on the display. ULTM

W

ill exit this state when level decreases by at least 0.8˝ (2 cm) below the full level.

w

D) Far Blocking Distance (FBD)

ULTM normally measures distance to targets which are closer than the “Empty
Level”.

In some circumstances, ULTM might detect an echo which is further out than the
“Empty level”. This echo may be the result of the actual target below the empty
level, or a strong interference below the empty level. In such cases, ULTM would
report “Empty” and would transmit an SMS to report the event. If you expect
echoes further out than the empty level, and you prefer to avoid these event
reports, you can define a Far Blocking Distance (FBD). Once defined, ULTM will
completely disregard any echoes beyond the FBD. If no other echoes closer than
FBD are detected, the ULTM will report loss of echo.

The default for “Far Blocking Distance” is identical to the maximum range of ULTM.

E) Near Blocking Distance (NBD)

If distance between the sensor face and the topmost level of the target is larger
than the specified “dead zone” by at least 2.7˝ (5 cm), you should consider defining
a Near Blocking Distance (NBD). The NBD should be defined as 0.8 to 1.2˝ (2 to 3
cm) shorter than the distance to the topmost level. This will ensure that the ULTM
will not measure obstructions slightly above the topmost level and mistakenly report
them as full level.

Contact Alert

Contact alert identifies a change of an external on/off state and transmits an SMS

lert to report the event. The contact alert does not affect other SMS message

a

ypes which are initiated by ULTM. The on/off states identified by ULTM are

t

PEN/SHORT between pins 5 and pin 4 on ULTM connection board.

O

A change in state is reported only if the new state persists for more than 10
seconds. No SMS is transmitted if the state toggles for less than 10 seconds. A
change to OPEN state is reported by a standard SMS message with status field “9”

last field in the SMS message). A change to SHORT state is reported by a

(

tandard SMS message with status field “8”.

s

At ULTM turn-on, a special message is transmitted to report the initial contact state
with “9” designating an OPEN state and “8” designating a SHORT state.

Default Values

LTM is preset by the manufacturer to a set of default values. The user may revert

U

t any time to these default values by performing the reset-to-default operations as

a

escribed in the configuration chapters under “Device States”.

d

Changes to the values made by the user will remain intact (survive equipment
on/off) only after the user returns to the measurement screen.

he table below defines the default values. A default value may automatically

T

hange in response to a change in some other value. For example, default value of

c

ull is 5.9˝ (0.15 m). This value will automatically be changed to 1.6´ (0.5 m) if NBD

f
is set to 1.6´ (0.5 m).

Similarly, when an extension pipe is used and the length of the extension pipe is
larger than the “dead zone”, you should define NBD which is larger by 0.8 to 1.2 in
(2 to 3 cm) than the length of the extension pipe. This will ensure that you will not
pick up echoes arising from the bottom end of the pipe and report them as full level.

If no other echoes further than the NBD are detected, the ULTM will report loss of
echo. The default for “near blocking distance” is identical to the “dead zone”.

Application Type

Application type allows some tuning of the internal GSM algorithm to be tuned to
the application. The application may be selected as low power or high power.
Always use low power for stable measurements unless your target appreciably
attenuates the echo such as: powder solids, liquid with foam, or long extension
pipes.

Cellular Communication

ULTM is equipped with an integrated cellular modem allowing periodic reports of
measured data and immediate alerts. Alerts include empty and full states and
excessive level change rates. Excessive level change rates may indicate theft or
tank refilling or an approaching flood. The user can configure the destination phone
number, periodic reporting interval, normal level change rates and more. The user
can activate or deactivate specific alerts.

• A 10 digit phone number 0541234567 may be entered as any of the following:

• The number *2345 may be entered as any of the following:

appropriate. It is your responsibility to insert the correct phone number as phone
number schemes vary worldwide.

Distance Units and Value to Display

Either meter or feet may be selected for the distance unit. This selection defines the
complete unit system being used by ULTM. Selecting meter as your distance unit
implies the Metric unit system.

False Echo Scan

False echo scan is a procedure for identifying and extracting fixed obstructions
nearby the target or sensor. This procedure should be performed when the tank is

mpty. This procedure is initiated from the keypad only. Further information is

Filling Rate

Filling rate allows you to tune the tracking of ULTM to fast moving targets. You
should increase the filling rate figure if your target fills up or drains down rapidly.

lways use the lowest possible filling rate in order to preserve accuracy of the

A

easurement. A high filling rate will allow better tracking before lost of echo when

m

he target moves rapidly. For nearby full (empty) levels, the tracking rate is reduced

t
to avoid erratic entry into full (empty) level.

Full and Empty Alerts

You may activate or deactivate full and empty SMS alerts. Full and empty alerts

o-exist with periodic alerts. A three-minute quiet interval is maintained between

c

wo alerts. Within this quiet interval time, no SMS alerts will be sent.

t

GSM Display Status Reports

The following status reports may be presented (or shown) on the display:

Error Indications

GSM REGISTRATION FAIL
GSM MODEM NOT READY
GSM TRANSMISSION FAIL
GSM SIM FAIL
GSM NOT ACTIVE

The Sequence of Status Reports is as Follows:

When ULTM is turned ON, it first searches for a proper level target. Once found,
ULTM begins to seek for a ULTM network. A status report GSM INITIALIZING will
be displayed at this time. The search for GSM network may take between 10
seconds and up to a minute.

If ULTM fails to locate a GSM network, one of the error indications will be displayed.
When such an error occurs, verify by using a cell-phone that the area is indeed
covered by a GSM network and that the SIM card you inserted into the ULTM is
good. Let ULTM do some retries for 30 seconds and then turn ULTM OFF and then
ON again to try again.

If ULTM successfully locates a GSM network, the status report GSM PERIODIC
ACTIVE will be displayed. When an SMS is transmitted, a sequence of status
reports will show: GSM DESTINATION ASSIGNED, GSM SMS SENT, and GSM
PERIODIC ACTIVE. GSM EVENTS ONLY report is displayed if the user disabled
periodic SMS reports. Disabling the periodic SMS report is performed by entering
0 (zero) at the report interval, either manually or by using the PC configuration
command SMST.

ULTM Reporting Interval

You can determine the periodic reporting interval using one of the configuration
methods. The interval is defined in seconds. For example, for an SMS report once
every hour, modify the interval to 3600. Report intervals lower than 180 seconds
are not accepted and will revert to 180 seconds. Maximum report interval is
3,999,999 seconds, which comes up to about 45 days. A reporting interval of 0
(zero) disables the periodic reports.

GSM INITIALIZING
GSM REGISTRATION SENT
GSM ACTIVE
GSM DESTINATION ASSIGNED
GSM SMS SENT
GSM EVENTS ONLY

The PTS turns ULTM ON to take a measurement and to transmit the measured
information. Then the PTS turns ULTM OFF for a sleeping period. ULTM is then
turned ON again and so on. With this method, a 20 AH/12 V battery can typically

eed ULTM for 1 to 3 years before replacement is needed.

f

wo different sleeping intervals may be programmed by the user: long interval and

T
short interval.

The sleeping interval in-effect depends on the level being measured. For example,
assume that a river overflows at a level of 6.6´ (2.0 meters) and calm waters are

efined at a level of 3.28´ (1.0 meter). Then you can define a very long sleeping

d

nterval (e.g. 6 hours) when level measurement is between 0 and 3.28´ (0 to 1.0

i

eters). You can further define a short interval of 30 minutes when the level is

m
between 3.28´ (1.0 meter) and 5.98´ (1.8 meters). Finally, above 5.9´ (1.8 meters)
the PTS may be disabled and ULTM will operate continuously.

When operating continuously, the period between messages is defined by the
ULTM reporting interval parameter.

This concept is further described in the following figure:

Vessel

PTS parameters are defined by the command LPST as described in the Chapter 4
“Configuration with a PC”. Both sleep intervals must be longer than 10 minutes. The
SMS messages during the long sleep interval may be cancelled. Do not configure
ULTM while the system is connected to a battery through the PTS. A shutdown may
be forced by the PTS causing loss of data.

Refill Alerts

When refill alerts are activated, ULTM identifies a refilling process. ULTM transmits
an SMS soon after the refilling is identified and a second SMS soon after the
refilling process has ended. The first SMS provides distance information (distance
between sensor and fuel surface). The second SMS provides information about the
filling quantity. This procedure allows more accurate refilling information when
compared with the information that can be extracted from periodic reports.

Reset and Operating Hours

ULTM may be reset to their factory defaults. This operation may be performed from
the keypad or from the PC configuration tool (command RSD). Once executed, the
ULTM will return to the state as delivered from the factory. ULTM may also be reset
to restart without any change in the pre-configured parameters (command RST).

ULTM keeps track of two counters for measuring operating hours.

• Non resettable counter (Odometer principle)

• Resettable counter (Trip-meter principle)

he non-resettable counter displays the total hours of operation since the system

T

s out of the factory. This counter aids both manufacturer and user in keeping track

i

f specific ULTM history. The resettable counter displays the total hours of

o

peration since the recent turn-on of the equipment or since the last reset of this

o
counter. This counter aids the user in keeping track of the equipment for
maintenance and other operations. The resettable counter may be activated from
the built-in display or using the PC command RSC.

Temperature Sensors, Units and Display

ULTM systems implement automatic compensation of deviations due to
temperature variations in the air temperature of the ultrasonic media. The
temperature is sensed by a temperature sensor which is embedded within the
acoustic sensor. In installations where temperature varies very rapidly in time and
location, it may be preferable to install an external temperature sensor ULTM-EXT
which will follow more closely the varying temperature.

For these installations, you can select the internal embedded temperature sensor
or the external temperature sensor (if one is connected), or average both readings.
Physical connection and installation of the external temperature sensor is
described in the Chapter 2, physical installation guidelines. Temperature units may
either be selected as Celsius or Fahrenheit. Temperature may be viewed on the
built-in display. Temperature readings on the display present the following table:

sensor. The column “Cur” displays the current temperature, while “High” and “Low”
columns display the highest and lowest temperature recorded by the temperature
sensors since the last reset was performed.

Theft alerts

ULTM supports theft detection alerts by examining the rate of liquid consumption.
Determine the rate which would be considered as inappropriate in units of level per
minute (e.g. mm/min) or volume per minute (e.g. liter/min) and modify the deviation
number accordingly. Limits are defined in Chapter 4: “Configuration with PC” (p.8).
Rates lower than 4 mm/min may cause excessive false alerts. Therefore, entries
lower then 4 mm/min will automatically be converted to 4 mm/min. It is
recommended to experiment with the specific tank and environment with this figure
until no false alarms are transmitted.

Recommendation

. Check the rating of your power supply and verify these ratings are within the specifications of the ULTM.

1

. Check the electrical cables between the power supply and the ULTM. In particular, check the connections on the ULTM.

2

. Check the rating of your power supply and verify these ratings are within the specifications of the ULTM.

1

2. Check if a USB connection powers up the ULTM – do not use a USB connection to power up the ULTM.

1. Check your target is between 5.9˝ (15 cm) and 26.2´ (8 meters) (19.7´ (6 meters) for solids).
. Verify that the sensor is precisely directed towards the target.

2

. Check the sensor face and make sure the face is clear of dust or dirt.

3

. If you use an extension pipe, recheck all the recommendations stated in the extension pipe section in this manual.

4

. Check that distance measurement is correct. Verify the settings of Full level and of Far Blocking Distance.

1

1. Check and clear out physical disturbances above the empty level.

2. If you are using an extension pipe, increase NBD to a distance which is 0.8 to 1.2˝ (2 to 3 cm) beyond the edge of the pipe.

. Verify you have properly inserted a SIM card into the ULTM.

1

. Carefully walk through the SIM instructions in the installation chapter.

2

. Reposition your cellular antenna; the cellular coverage may be weak in your area.

3

1. Verify the correctness of the destination phone number that you entered into ULTM. Review the rules for entering a

phone number as described in this manual. Remember, it is your responsibility to enter a valid phone number.

1. Check if the reporting interval you entered in the ULTM is correct. Notice that reporting interval is entered in seconds so

that half an hour would be entered as 1800 and five minutes would be entered as 300.

. Check if the reporting deviation is set to zero.
