Water Detection Loggers and Sensors

These sensors and systems can detect the presence of water or the absence of water.  You have the option to simply record the event or you can install alarms to provide an alert when water is present or is not present.  These units are used to record or alarm users on the event of a dry well, leaks, ephemeral streams and so on, there can be many uses.

Water Detection Logger

Intermountain Environmental has designed the following system for the EPA.  This system has been designed to monitor dry stream beds (ephemeral) for the presence of water.  The EPA has been using these systems for many years.  The logger will record the time and date of when it senses water and then record when the water is no longer present.  This will tell you the length of time that water was in the stream bed.

The logger is housed in a water tight container and the sensor is installed through a liquid tight cable seal on the bottom of the container.  The logger is an event logger form Onset Computers.  The software used is HOBOWare, also from Onset. 

The sensor is comprised of two copper rods installed on either side of a plastic spacer rod.  When water is present an electrical circuit is created between the two copper rods.  This is how the logger sense the presence of water.  There are currently two models available: a 2 meter or 3 meter cabled sensor.  We can do custom lengths if desired.

Water Detection Sensor and Alarm

The Water Level Alarm Sensor (WA600) is a solid state water sensor for detecting the presence of conductive solutions, such as water spills, water tank levels, and drainage ponds. The water alarm sensor features two stainless steel electrodes that are positioned at a desired point for liquid detection.  When fluid is detected, a relay closes in the water level alarm and the signal can be used to sound an audible alarm or close a switch inside a piece of remote monitoring equipment.  The relay output is fully isolated and can handle 2 amps of current. After the water level alarm sensor is in dry conditions, the detection sensor will automatically reset without requiring additional service.  The water level alarm is rugged and durable and requires minimal maintenance. The Water Level Alarm has many uses, including: surface water monitoring, precision level detection, water level control, high water indication, and submersible marine low level indication.  The water alarm sensor can be purchased to trigger an alarm upon contact with water or air.

The WA400 Water Level Alarm is robust and easy to install anywhere you need a reliable high or low water level alarm.  The WA400 features a weather resistant PVC enclosure for outdoor applications, a bright flashing strobe light and loud sounder for alarm notification, and a choice of versions and accessories.

The WA600 can be combined with the Campbell Scientific loggers to create a water detection logger and alarm system with many options for recording data and alarms. (CR800 Logger Pictured on Left)
