Field of application

Tube400-Open is a battery-operated datalogger and telemetry device, designed for monitoring environmental parameters such as water and air quality, water levels and flow, and groundwater.

It performs all key tasks at every measurement station, from data collection and storage to data and alarm transmission.

In its standard configuration it has an IP67 tubular housing, suitable for insertion into 2″ wells. A board-only version is also available for OEM.

Data collection and transmission

Tube400 collects data and stores it in internal memory: data can subsequently be sent via FTP or email to the required destination.

Units remain in sleep mode most of the time. The internal real-time clock wakes them up, according to setup parameters, for sensor readings or data transmission.

Sensor interfaces

Tube400 has several interfaces for connecting external sensors (RS485, RS232, SDI-12, 0-10V analog input, 4-20mA analog input, digital input), all available simultaneously.

Two internal sensors are built into the unit: an atmospheric pressure sensor (for automatic compensation with non-vented level sensors) and a thermometer for ambient temperature.

Power supply

Tube400 allows the use of different power sources: 3 primary 3.6V D-Size lithium cells, or 3 alkaline 1.5V batteries.

External power and internal battery can also be used simultaneously.
