Decentlab DL-PR36 | High-Precision Pressure / Liquid Level and Temperature Sensor
The device DL-PR36 enables remote monitoring of water levels in open water, fill levels of tanks, groundwater levels, and various other applications. It measures the pressure at the sensor head relative to the pressure at the cable end (device enclosure).

- Smart Industry
- Smart City
- Tank level monitoring
- Liquid level sensor
LoRaWAN® -enabled high-precision piezoresistive pressure sensor / depth gauge including temperature sensor.
Pressure measurement relative to atmospheric pressure (absolute pressure on request).
Range: 0 ... 1 bar (0 ... 10 m); up to 30 bar (300 m) on request.
Cable length: 10 m (custom lengths on request).
RS-485 interface for robust operation in harsh environments even with cable lengths of several hundred meters.
Compatible with LoRaWAN® networks of any provider.
Place and measure: no setup required.
Configurable via command line interface and downlink command interface.
Unattended real-time monitoring for several years without replacing batteries.
Robust polycarbonate enclosure:
weatherproof, impact-, UV-resistant (IP67).
Standard alkaline (C-type) batteries.
CE compliant, Radio Equipment Directive (RED) 2014/53/EU.
When the sensor head is placed underwater (or any other liquid), the relative pressure indicates the depth of the sensor head. In water, the relative pressure of 1 bar equals a depth of approximately 10 m. Also available on request is a variant of the DL-PR36 which measures the absolute pressure at the sensor head, i.e., the pressure relative to zero bar (vacuum).
The device also reports the temperature of the sensor head with high precision. The temperature reading is also used internally for temperature compensation.
APPLICATIONS
Level/depth in tanks for liquids
Boreholes
Groundwater and wells
Running or open water level and quality
Salinity and chloride monitoring
