Plug & play integration with the LineMetrics platform
Description
The LoRa Pulse Meter is an advanced LoRaWAN® pulse meter that transforms any metering device, such as conventional water meters, into smart wireless meters. It is suitable for use in various demanding environments thanks to its waterproof IP67 design. This sensor is designed for “DryContact” digital outputs. Utilizing LoRaWAN® technology and a built-in high capacity battery that lasts for several years without replacement, the LoRa pulse meter enables efficient remote monitoring and intelligent data management for water conservation. The sensor is compatible with the Linemetrics platform and offers flexible application possibilities, both indoors and outdoors, including agricultural irrigation, industrial water use and real estate metering.

Measuring points
Data acquisition
- The number of pulses is sent to the server every 10 minutes.
- Pulses up to a minimum pulse duration of 250µs can be detected
Visualization
Pulse input:
Calculated input:
Water requirement of a supply line of an industrial hall. The upper graph shows the raw data, i.e. the number of pulses. Since one pulse of the water meter has a value of 10 liters, the consumption can be automatically converted into liters. The result, i.e. the actual consumption, is shown in the graph below.
Data acquisition
- The air temperature is recorded and transmitted every 10 minutes
- Value range: -30° to 70°C (0° to 70°C accuracy: +/- 0.3°C; -30° to 0°C accuracy: +/- 0.6°C)
Visualization
Temperature profile for a month in a warehouse for electrical materials. As can be seen, critical temperature values of 0°C and below were not reached. The color-coded areas can be configured individually.
Data acquisition
- The relative humidity is recorded every 10 minutes and sent on.
- Value range: 0 – 100% RH (10% to 90% accuracy +/- 3%; below 10% and above 90% accuracy +/- 5%)

Tested for you: The best sensor on the market
This sensor has prevailed against comparable models in our test laboratory and has proven itself in practice.
Enorme Funkreichweite: Ganze Gebäude abdecken
Many kilometers of range outdoors or hundreds of meters indoors – no comparison with WiFi! More >
Battery-operated with up to 3 years runtime
LoRa radio is very energy efficient. Depending on the quality of the wireless connection, the batteries will last for many years.
Plug & Play integration into the overall system
It’s easy to obtain your first measurement data in just a few minutes thanks to the modular system – from the sensor to the cloud.
Your benefits with the LineMetrics platform
All-in-one: A complete system for room monitoring
1. Digitize meters
The battery-operated wireless sensor can be installed in any room. It reliably records all values and transmits them via LoRa.
2. transmit measurement data
The LoRa wireless gateway creates a wireless network for up to 1,000 sensors. The collected measurement data is transmitted to the cloud via mobile radio.
3. evaluate and alert
All sensors are managed and all measurement data stored in the cloud. Analyses, alerts and data integration via API are easily possible.
What is behind it? Find out what LineMetrics can do to help you easily obtain the measurement data you need.
Developing and operating an IoT-based monitoring solution is more complex than many people think. Here is just a small excerpt of what LineMetrics can do for you in the background so that you can easily and reliably obtain the measurement data you need:
- Selection of international suppliers, supply chain management and price negotiations
- Selection and testing of individual hardware devices, hardware quality management
- Device and firmware management
- Optimizations in terms of radio range and battery life
- Database management
- Connectivity management (SIM cards)
- Security and encryption, including updates
- Creation of instructions and support during rollout
- 24/7 monitoring of the entire solution, support in the event of problems
Cloud platform: Analyze and process measured values
The LineMetrics Cloud allows you to create individual dashboards on which you can keep an eye on the data that is most important to you. Measured values can be displayed, combined and colored in the form of bars, curves, dial gauges, etc. This screenshot shows past and current measured values of the sensor:
Warning messages can be created for individual ranges/limit values and provided with a trigger delay. This means that no warning is sent if critical values are only briefly exceeded. A second condition for triggering a warning can also be configured.
Alerts can be sent by e-mail (see screenshot) or SMS. The recipient, subject and message can be easily configured individually.
Plug & play: obtain measurement data quickly and easily (< 3 minutes!)
The LineMetrics complete solution enables the solution to be commissioned via plug & play – without technicians, IT department, cable laying and network access. We will send you all the hardware with all accessories and simple commissioning instructions. The first measurement data can be analyzed in the LineMetrics Cloud within a few minutes. For questions, problems and tips, we have set up a comprehensive service center for you and can of course also be contacted personally at any time.
