1. PRODUCT OVERVIEW

1.1 SUTRON RADAR LEVEL RECORDER (RLR-0002-1)

The RLR-0002-1 has a front panel that allows a user to setup the operating parameters, monitor performance and

perform tests. The RLR-0002-1 is both a sensor and a logger, allowing for stand-alone and integrated applications.

The log inside the RLR-0002-1 is capable of holding more than 300 000 readings, and allows the recording of status

and stage (stage) data. The RLR-0002-1 has an SDI-12 interface as well as RS232 so it can provide data to data

loggers or communications equipment.

The RS232 port supports a simple command line mode compatible with HyperTerminal and

other communications programs to display data from the log and perform some essential

operating functions. It is possible to connect the radar to a modem or radio.

Features

• Non-contact measurement of stage (water level).

• Low power consumption (<1ma quiescent, <20ma measuring @ 12V) for long battery

life.

• High precision featuring 0.001 ft resolution a range of 60ft.

• High accuracy 0.01ft 5- 20ft, 0.05% reading 20-60ft.

• Powerful and configurable processing filters out waves (Averaging and DQAP)

• Automatically saves data in permanent log
