No gateway or base station needed

All of the new generation of Celsicom measurement products have a direct, secure transfer of data to the cloud without the need for a base station or gateway. The data traffic is sent on a licensed frequency exclusively for NB-IoT on Telia’s existing mobile network. Coverage is excellent and the risk of interference is virtually zero. On your mobile phone, you then monitor the pressure and flow of the reference device.

Clear interface

On the Celsiview mobile website, enter the K-factor and the projected flow of the reference device. The adjustment is made according to the proportionality principle. That is, the mobile shows the reference device’s flow as a percentage of the projected flow and what flow the other devices should be adjusted to. If there is a change in pressure, the values are recalculated within seconds, so you always have up-to-date measurement data from the reference air outlet meter. The interface can be set to display the flow in l/s or m³/h and the pressure in Pa on the sensors.

Easy to get started

To start using the Celsicom V600, simply scan the QR code inside the meter and log in (or create an account) to the Celsiview cloud service where you also register the hardware. Shortly afterwards, you can easily make the settings and start the adjustment work via your mobile.
