7 Rainlogger

The Solinst Rainlogger (Fig 7-1) is designed to count the tips of an external
tipping-bucket rain gauge within a user defined sample interval and output the
total rainfall over that sample interval. The Rainlogger can store 40,000 readings.
The Rainlogger is designed to be compatible with the Solinst Levelogger series
of products and is therefore programmed and data is viewed and exported using
the Levelogger Software. It can be communicated with using a Leveloader Gold
and can be integrated into an STS Telemetry System or PLC/SCADA network
using SDI-12 Protocol.
Figure7-1 Solinst Rainlogger
The Rainlogger can be set up to log rainfall at intervals from 5 minutes to 99
hours and also calculates and presents the maximum 5 minute rainfall intensity
within a minimum 15 minute sampling interval. The waterproof housing is
made of stainless steel. Direct exposure to rainfall should be avoided, and the
Rainlogger should not be submerged.

7.1 Rainlogger Communication Interface

The Rainlogger is compatible with Solinst Levelogger Gold accessories. It is
programmed using the Levelogger Gold Software. It connects to a laptop or
desktop PC using a Solinst Optical Reader, or a Direct Read Cable and PC
Interface Cable combination. Stored data can be accessed using a PC or
Leveloader Gold. Settings files can be uploaded to the Leveloader Gold and
used to program the Rainlogger in the field. The Leveloader Gold comes ready
with Optical Reader and PC Interface connections.
The Rainlogger is also able to integrate into a Solinst Telemetry System. It
is connected to a Direct Read Cable, which is then connected to an armored
reader cable to the remote telemetry station.

Rain Gauge Connector

The rain gauge connected to the Rainlogger is supplied by the customer and is a
reed-switch type gauge most commonly known as a tipping-bucket rain gauge.
The rain gauge connector is 3-pin (Fig 7-2) and connects to the 3-pin cable
supplied with the Rainlogger. Longer cables up to 30 m (100 ft) can be supplied
when the Rainlogger is ordered. The connector cable has 3 wires, however only
two, the blue and brown wires, are connected to the tipping bucket device. As

on the tipping bucket the blue or brown wire is connected. Longer, exposed
cables should be protected from rodents and vandalism by cable armoring or
