Decentlab DL-PR21-001 - Pressure / Liquid Level sensor for LoRaWAN

IP67, Integrated battery & antenna, -1 til 10bar, G1/4'' threading

The DL-PR21 enables remote monitoring of pressure in pipelines or tanks. It measures the pressure at the G 1/4” pipe connection relative to the pressure at the cable entry.

When the sensor head is mounted at the bottom of a water tank, the relative pressure indicates the depth of the sensor head (fill level). In water, the relative pressure of 1 bar equals to a depth of approximately 10 m.

The device also records the temperature of the sensor head. The temperature reading is used for temperature compensation.

Decentlab DL-MBX is a LoRaWAN based device, compatible with any network server, allowing for ease of installation, long range wireless communication and long battery life of up to 14 years in the field.
