How to order?

Prior to ordering, you need to know the meter/sensor that will be monitored, the network that will be used. Once you know that you will have to define would you like to get the logger as a service with a smaller initial fee or as a piece of hardware (larger initial fee but smaller tax later on)?

Note that in either case all shipping expenses for the delivery of the logger will be covered by us.

Determine the type of meter that you have.

The first and most important is to have or plan to use a meter with pulse output.

Meters typically are mechanical water meters, ultrasonic flow meters, and flow mags.

If you wonder what kind of a flow meter do you have check this.

Determine the type of the network (could be 2G/GSM/GPRS, Narrowband IoT, or LoRa/LoRaWAN).


is the most widely used option. If you choose GPRS data logger it will come with an embedded global roaming SIM card ready for use. You don’t need to pay anything extra for the network service. The monthly fee covers the global roaming SIM costs.

Narrowband IoT

Newer cellular network option offered by mobile operators. Available only in certain countries. We can again supply the SIM card for most of the EU countries.


low power IoT sensor network – cost-effective option suitable if you want to build your own sensor network.

If you need information on the network/meter choices please don’t hesitate to contact us.
