Adding a metering device with a pulse interface

Before creating a gateway metering device you need to add the gateway itself. Instructions:

  • Creating a gateway (LoRaWAN Radio Modem)
  • Creating a gateway (GPRS modem)
  • Creating a gateway (Ethernet converter)

To create a gateway metering device it is necessary to take the following steps:

1. Go to the “Devices” section.

2. Click the “Add new device”.

3. Select “Add meter”.

4. Select a category.

5. Leave the switch off. That switch allows to create a device with a built-in modem.

A built-in modem means a built-in LoRaWAN module, a GPRS modem or an RJ-45 (Ethernet) interface in the device, which makes it possible to transmit data to a server or base station without using additional equipment.

6. Select the the metering device “Manufacturer”.

If the manufacturer of the meter is not in the list or is unknown, then you need to select the Other item, and select Pulse water/gas/electricity meter as the model.

7. Select the metering device “Model”.

8. Select the “Connection type” to the gateway.

The type of connection to the gateway is a wired interface through which the gateway is connected to the metering device. In this case it is Pulse.

9. Specify the “Pulse weight”.

For some meters’ models, Pulse Weight options are pre-set in the system and are available for selection from the drop-down list. If the desired option is not available, then it is necessary to do the following:

10. Enter the pulse weight manually.

Water and gas meters:


0.1 liters (0.0001 m) per pulse – pulse weight is set to 10000

1 liter (0.001 m) per impulse – the weight of the impulse is set to 1000

10 liters (0.01 m) per pulse – pulse weight is set to 100

100 liters (0.1 m) per impulse – we indicate the weight of the impulse 10

1000 liters (1 m) per impulse – indicate the weight of the impulse 1

10000 (10 m) liters per impulse – the weight of the impulse is indicated as 0.1

For example: In the manual for the pulse water meter, the price of the pulse is 1 liter (0.001 m3). Those. 1 liter = 1 impulse. To get the meter readings in cubic meters, you need to divide the number of pulses by 1000. Accordingly, in the Pulse weight field, enter the value 1000.

For electric meters:

For electricity meters, the Pulse Weight parameter is called “Gear Ratio” or “Meter Constant”.

It can be clarified with the manufacturer, in the instruction manual for the meter or on the front side of the meter.

The gear ratio is the number of pulses of the electronic meter in 1 hour at a load of 1 kW.

Ticking the checkbox “Add a device to a polling group” allows you to assign the polling parameters specified in a separately created Polling Group to the device. For a detailed introduction to the Polling Group function, follow the “link”.

11. Enter the “Name” of the metering device.

12. Select “Resource Type”.

13. Select the “Time zone” of the device.

14. Enter the “Serial (factory) number” of the device.

15. Select the “Gateway” to which the metering device is physically connected.

16. Enter the “Network (internal) address”.

In most cases, the gateways have several inputs for connecting pulse metering devices. In the system, these inputs are named In1, In2, etc. It is necessary to select the input to which the meter is physically connected.

17. Enter the “ID” of the metering device. The name is entered arbitrarily.

18. Enter the “Starting value”.

The starting value is the readings on the meter at the time of creation of the metering device in the system.

19. Select the “Activity Timeout” of the device.

Activity timeout is a parameter that is responsible for the frequency of the system checking the activity of the device in the Nekta system. Activity means receiving a package with data of any type from the device (readings, archives, logs, power profiles, alarms, receipts, etc.)

20. Check the specified parameters and click the “Create button”.

At the time of creation of the pulse metering device, it is necessary to reset the accumulated pulses on the gateway (modem).

The creation of the metering device is completed.
