1Overview
ThingsLog LPMDL-1101 is a universal, low power mobile data logger able to meter various kinds of pulse meters
and analog sensors. The logger is transmitting the metered data over 2G/GSM/GPRS.
LPMDL-1101 has the following key characteristics:
Optimal data transmissions - LPMDL-1101 is able to transmit the data over a two-way GSM/GPRS network in
an optimal for the battery way. That allows the logger to meter per minute, to transmit a couple of times per
day and still to achieve more than 5 years of battery life.
Intelligence - the data is transmitted over a widely distributed, cellular network and is automatically gathered
in ThingsLog platform.
Pulse metering - LPMDL-1101 has ability for an independent counting of pulse output meters for water, gas,
electricity and heating. With a single data logger, you can meter two meters for example for cold and hot water
or if your meters are in proximity distance you can meter with a single device gas, electricity and heating.
Analog sensors metering - LPMDL-1101 has two extra inputs for connecting analog sensors with 4-20 mA
output. An example could be connecting two pressure sensors or one pressure and one temperature sensor.
Combined monitoring - LPMDL-1101 can fulfill use cases where with a single logger have to be monitored one
water meter and two pressure sensors. For example monitoring of pressure reduction areas by measurements
of pressure sensors before and after the pressure reduction valve and its water meter.
Alarms and notifications - LPMDL-1101 together with the ThingsLog platform is able to monitor consumption
and notify the customer or the utility company for leaks, high or low consumption, fraud or thresholds bridging
of certain sensor value or a combination of a sensor and metered value.
Application - LPMDL-1101 fulfills various use-cases in Water, Electricity and Gas distribution utilities but also
many other use-cases in property management, hotel, manufacturing, condominium sub-metering or in
common need is spread.
Ability to work in any environment - LPMDL-1101 has IP68 dust and leakage protection and is suitable for any
kind of home or industrial usage.

7User guide
7.1 Login to ThingsLog platform
1. In order to perform the initial configuration you should have an account for ThingsLog IoT platform.
If you don’t have an account please contact us at [email protected].
2. Once you have the account navigate to https://iot.thingslog.com

Visit us at www.thingslog.com; ([phone]; [e-mail]
3. You should be able to see a device list with the devices associated to your profile.
7.2 Initial configuration ThingsLog LPMDL-1101
1. Connect your logger to your meters and sensors as described in section physical installation.
2. Navigate to menu “All Devices” - and pick your newly added logger.
Figure 6 Menu “Devices”
3. From the menu choose “Config” then a similar configuration dialog will appear.

Visit us at www.thingslog.com; ([phone]; [e-mail]
Figure 7 Configuration dialog

Visit us at www.thingslog.com; ([phone]; [e-mail]
On the top you can see the logger id, date when it was configured for a last time and current
configuration status.
Then follows the common section for all inputs/outputs.
●Transmission period - Number of minutes/hours/days between the logger scheduled
transmissions
●Record period - Could be Minutes or Hours. This is the period on which the logger will log in
memory the reading values from the pulse inputs or the period on which it will perform low
power reading of its analog current inputs.
4. Pulse sensors
Pulse sensors are typically meters connected to a pulse input port or buttons. To enable the port
please slide the slider to the right and enter. Once the port is enabled you have to set the following.
Figure 7 Pulse input port configuration dialog
●Digits - Number of digits - equals to the number of digits on the display of the meter
●Fraction - Number of digits after the decimal pointer on the display of the meter

Visit us at www.thingslog.com; ([phone]; [e-mail]
●Initial reading - Initial value of the counter of the meter
●Sensor type –the type of the sensor could be water, gas, power etc meter.
●Units type –the dimension of the metered values –m3, kw etc.
●Pulse per unit –how much of the measured value is equal to one pulse
5. Analog sensors
Figure 7 Analog input port configuration dialog
To enable analog sensor readings (connected to the analog inputs) just slide the slider to the right
and configure:
Sensor type –the type of an analog 4-20mA sensor we are measuring
Sensor conversion formula –convert the “x” into bars or something else based on the
formula for conversation of mA to the required dimension of your sensor. If you leave it as x
you will get values in mA.
Units type –the type of the unit –mA, bar, etc.

Visit us at www.thingslog.com; ([phone]; [e-mail]
Low Level Alarm –Instant alarm for reaching certain low level analog sensor value
High Level Alarm - Instant alarm for reaching certain high level analog sensor value
6. ON/OFF sensors
To enable the ON/OFF sensors slide the slider to the right. The sensors has to be normally open
ON/OFF sensors. If the port is enabled and the sensor goes from OFF to ON the logger will wake and
will transmit an instant alarm.
7. Delete old counters - once you are ready with the inputs configuration decide do you want to keep
the old values or not. If not choose “NO” else chose “YES”.
8. Once you are ready press “Start Setup” button.
This will start a 1000 seconds counter. You will have to touch the logger with a magnet prior the counter
expiry. This will put the logger into configuration mode and it will try to obtain its configuration from the
server.
9. If the logger get configured successfully you will be able to see the following message on your screen.
Figure 8 Confirmation of successful configuration
If the configuration process is unsuccessful and the device stays in “Not configured” mode please
ensure that the device has been placed in an area with proper GSM coverage. If you are not sure that such is
available in your area please let us know at suppor[email protected]m.

7.4 Operational considerations
7.4.1 Dashboard
Navigate from the menu to the “Dashboard” where you can verify the operational status of your
loggers.

Figure 13 operational status dashboards
ThingsLogТМ supports the following kinds of alarms:
●NO_ZERO_CONSUMPTION - alarm for non-zero consumption. The non-zero consumption is defined
as condition in which the logger is detecting constant consumption over a period equal to the
transmission period.
●HIGH_CONSUMPTION - alarm indicating consumption higher than a certain preconfigured level over
certain period. For example 1m3over 1 hour.
●MISSED_TRANSMISSION - alarm indicating that the transmission from the logger did not happen.
●LOW_FLOW - alarm indicating that the flow time interval is lower than the expected value per
second.
●HIGH_FLOW- alarm indicating that the flow time interval is lower than the expected value per
second.
●HIGH_CONSUMPTION - alarm indicating that the consumption time interval is lower than the
expected one.

Visit us at www.thingslog.com; ([phone]; [e-mail]
●ALL_ZERO_CONSUMPTION - alarm signaling zero consumption through certain time-period. For
there is no consumption for 24 hours. Could potentially indicate a fault meter.
●DEVICE_REMOVED - alarm indicating that the meter has been disconnected from the logger.
●LOW_BATTERY - alarm indicating that the battery of the logger is under 20%.
●ON/OF alarm –on/off sensor is enabled and an instant alarm is triggered
7.4.2 Battery status
Battery status in % of your logger. The same could be reviewed in more details if you navigate to “Battery”
section of the product.
Figure 13 Battery status

Visit us at www.thingslog.com; ([phone]; [e-mail]
Since our loggers are with battery holders we sometimes don’t exactly know what kind of a battery is inside
the logger. Therefore the more important value is the voltage in mV. The level in % might be incorrect
depending of the type of the logger and the battery you have placed in.
7.4.3 Signal status
On each transmission, the loggers are sending their current measured RSSI (Received Signal Strength
Indication) and BER (Bit Error Ratio) if there is an error.
