SOFREL LT-US: DL4W-HP Datalogger


SOFREL LT-US: DL4W-HP Datalogger

Waste water and storm water networks
Equipped with a high performance GSM antenna, the waterproof (IP68) energy autonomous SOFREL LT-US DL4W-HP Datalogger fulfills the instrumentation needs of water networks.

Thanks to its ultrasonic sensor for level measurement, the LT-US data logger provides continuous monitoring of flow to the collectors or discharges to the natural environment.

Simple to install, offering excellent autonomy (battery powered), the LT-US DL4W-HP Datalogger offers a perfectly optimized solution for the control and use of wastewater and stormwater networks:

self monitoring
Continuous diagnosis
Flow measurements and calculations
Stream recording according to alert thresholds…
Main Functions
Offering 2 digital inputs (DI) for event signal (buffer opening, overflow occurrence, sensor faults, etc.) along with 1 optional analog input (AI) (level measurement), SOFREL LT-US combines functions that allow it to:

Connect to overflow sensors (SOFREL CSV or others),

Measure level via 4-20 mA ultrasound sensors (sensor works directly with LT at 12V),

Calculate daily overflow numbers and times,

Timestamp each overflow event
Automatically archive water height according to variable time intervals,
Control an autonomous sampler,
SMS sending alert when a threshold is exceeded when changing a DI state,
Periodic, scheduled or event based communication with 1 or 2 PCs.

An ultrasound probe fully controlled by the data logger
Fully integrated into the LT-US, the ultrasound probe is powered directly from the data logger battery. Combined with an overflow detector and variable archiving frequency, the runtime reaches ten years. The data logger is initialized. The ultrasound probe is easily calibrated using the SOFTOOLS graphical user interface via a Bluetooth connection. The remote management of the ultrasound probe (up to 5 meters) is to place the data logger in the best area of GSM reception (the highest in the manhole) by placing it as close as possible to the measured wastewater. point) amount.
