1 Overview
ThingsLog LPMDL-1102 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 4G/NB IoT.
LPMDL-1102 has the following key characteristics:
Optimal data transmissions - LPMDL-1102 is able to transmit the data over a two way 4G/NB IoT 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 10 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-1102 has ability for an independent counting of pulse output meters for water, gas,
power 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, power and heating.
Analog sensors metering - LPMDL-1102 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-1102 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-1102 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-1102 fulfills various use-cases in water, power 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-1102 has IP68 dust and leakage protection and is suitable for
any kind of home or industrial usage.

4 Safe and Healthy instructions
Important
information
Please read the complete information, the specifications, the installation
instruction and the electrical interconnect schema prior to working with this
product.
For your own health and safety and for the equipment to function correctly
please ensure that you understand completely the contents of this guide, prior
installation, configuration, operations or profilactics.
CE
From license point of view, unauthorized modifications or additions are not
authorized.
Terms of use
The data logger is intended for use in the following environmental conditions:
●for use indoors or outdoors without prolonged exposure to direct UV
radiation
●for altitudes up to 2000 m
●for ambient temperatures from -40 ° C to + 60 ° C, with continuous
exposure to temperatures of -20 to -40 ° C not recommended

Health and safety
rules for installation
All installation work must be performed in accordance with the local regulations
on health and safety at work in electrical systems as well as the regulations
governing the electrical system and networks.
Only engineers or technicians with product expertise that has previously read
and understood this guide should install this product.

Installation and
maintenance
Installation is done in accordance with the instructions in this document.
Incorrect installation may cause damage to the logger and inaccurate
measurements. That is why the installation, the initial configuration must be
done with due attention.
Incorrect installation results in violation of warranty conditions and failure of the
warranty.
An example of improper installation is to connect the pulse or analog input of
the device shortly or to a power source
Transport and
storage
Store in dry rooms without access to water or other liquids at temperatures not
lower than -20 ° C and not higher than 60 ° C in the original package.
Transportation is allowed to happen accidentally at temperatures below -20 ° C
but not more than 8 hours. Protect against shocks and avoid extreme
conditions.
Subsequent
maintenance
Once installed, the data logger should be cleaned using a dry or lightly
moistened cloth, explicitly prohibiting the use of aggressive and abrasive
detergents.
Every six months, it is desirable for the user of the logger to check the enclosure
integrity and the integrity and waterproofness of the cable and connecting
terminals to the measured device or sensor.

●Prior to install the logger please review the health and safety instructions described in chapter 3.
●The data logger is coming with an installation manual and a kit through which it can be attached
to a firm surface.
●In order to attach the logger you will need a wall with stiff, flat surface close to the meter or the
sensor which you would like to measure.
●Mark and drill holes with size 4x25 mm for attaching the logger to the wall.
●Attach the logger input/outputs to the connecting cable.
●Attach the corresponding connecting cable input/outputs to the meters/sensors.
