Dinel ULM-53-02

The Dinel ULM-53-02 level sensor measures levels from 0.2m to 2m.Data is transmitted via a 4-20mA converter and processed by the Poseidon2 3468 unit. The data can be sent to up to 5 email addresses and to the HWPortal.cz cloud controller. The Poseidon2 3468 features a 230V relay output and can activate any device (e.g., a pump) based on the measured level.
