OVERVIEW
Water Level Sensor Module:
The RX3000 Water Level Sensor Module (RXMOD-W1) offers users the ability to monitor water level, pressure, and temperature, as well as barometric pressure, with the HOBO RX3000 Remote Monitoring Station. It is configured through LI-COR Cloud IoT platform (formerly HOBOlink). For water level applications, a HOBO RX3000 station, Water Level Sensor Cable, and Water Level Sensor are required.
Highlighted Features
- Integrated barometric pressure sensor
- Plug-and-play remote water level and flow monitoring
Water Level Sensor Cable:
The water level sensor cable provides the connection between the HOBO RX3000 Remote Monitoring Station and the water level sensor. A HOBO RX3000 station, a water level sensor module (RXMOD-W1), and a water level sensor (MX2001-0x-S or MX2001-0x-Ti-S) are required for use with this cable.
Cables can be ordered in lengths from 1 meter to 400 meters for deployment in a wide range of applications. The 5, 10, and 15 metre cable lengths are standard. Custom cable lengths require a lead time of three to four weeks.
PLEASE NOTE: Custom cables are ineligible for return.
Highlighted Features
- Interchangeable Kevlar-reinforced cable can be used to suspend sensor
- Provides sensor communication and power
- Two O-rings in the water level sensor connector ensure a long-term waterproof seal
- Cables are easy to attach or change

** Raw Pressure Accuracy: Absolute pressure sensor accuracy includes all sensor drift, temperature, and hysteresis-induced errors.
*** Changes in Temperature: Allow 20 minutes in water to achieve full temperature compensation of the pressure sensor. There can be up to 0.5% of additional error due to rapid temperature changes.
Measurement accuracy also depends on temperature response time.
