Solinst Model 2001

Reelogger

The Reelogger is a water level and/or multiparameter datalogging system that introduces many new concepts ideal for field use by hydrogeologists, hydrologists and anyone wishing to monitor water automatically.

Operating Principles

The Model 2001 system uses narrow diameter, 'smart' parameter probe(s) connected in-line, or on a ring-mount manifold, to 2-conductor cable. Portable reel units may be fitted with Solinst flat tape, permanently marked each 1/100 ft or millimeter. Dedicated units may use inexpensive coaxial cable. The logger, barometer and a thermistor are housed in the reel or surface housing.

An LCD display with three control buttons allows instant viewing of readings, addition, deletion and calibration of probes, starting and stopping of logging, and much more, without any additional equipment. Infra-red, digital communication allows downloading and programming without use of cables.

Reeloggers have a very small but powerful datalogger which operates on standard 9V or AA batteries, and can store up to 100,000 readings in non-volatile memory.

The Reelogger software is very comprehensive and simple to operate on any Windows95 or later system. Linear or logarithmic logging is easy to setup. Programming and data download are rapid and digital. The software has extensive viewing and graphing capabilities.

Interchangeable Probes

The modular Reelogger system can operate up to 8 separate sensors, allowing the user a choice of which to purchase or use for any particular application.

All sensors have been designed for superior accuracy, durability, long-term stability , ease of use, and minimum calibration requirements. All probes are temperature compensated and the temperature readings from the #1 probes in line are also recorded. A temperature compensated barometer, housed in the reel, is used to compensate pressure measurements for atmospheric pressure. This eliminates the need for vented cable.

Simple Water Level Indicator

A simple water level indicator is incorporated into the probe/tape connector, permanently attached to the cable

Water Pressure Probe

The Solinst pressure sensor uses vibrating wire technology, as it is very accurate, rugged and stable over the long term.

Conductivity Probe

The Solinst conductivity sensor is a new highly accurate, very stable, 5-terminal cell.  It has 4 platinum electrodes within the sensing cavity and the stainless steel body acts as the 5th terminal to greatly reduce the effects of external water, giving consistent readings regardless of well size or low flow conditions.

pH Probe

The pH sensor utilizes a patented reference cell which provides greater than 3 months of continuous accuracy and reliability before recharging.  Recharging is very simple and can be easily performed in the field.

Temperature Sensors

The temperature reading displayed by the logger is the temperature output from the #1 probe in line.  Each probe has its own temperature sensor for compensation purposes.

The Logger

The small powerful datalogger operates for extended periods of time on standard 9V batteries, powering all the probes through the batteries.  The logger can log from 1 to 8 sensors, plus the built-in barometer and thermistor.

Software and Data Sampling

Solinst has gone to great lengths to simplify the input screens for teh programming of Reeloggers. The Windows 95 or later ReelPC software is very easy to use.

Linear sampling regimes can be programmed using either the Onboard3-Button software, or the ReelPC software. Multi-step sampling and logarithmic programming must be setup in the ReelPC software and transmitted to the Reelogger.  Up to 10 individually defined recording periods can be set up in one programming session.

Memory

The Reelogger stores up to 100,00 readings of time, barometer, temperature and other parameters. The data is stored using RL compression in 512 KB of non-volatile, flash memory, which prevents loss of data if the batteries run down.
