Monitor for the WaterWatch² Range

10 to30VDC , 2×0/4-20mA Output,3×Relay Outputs

The 7300w² Monitor is the core to the WaterWatch² product range,the monitor is designed to interface with all the sensors in the WaterWatch² range. The starting specification provides all the connections required for 1 or 2 sensors and systems can be created by the use of expansion boxes to include multiple sensors. The maximum number of sensors will be limited by the practicalities of most sites. We anticipate 8 being a sensible maximum although many more can be accommodated.
Combining sensors provides a very cost effective way of simultaneously monitoring parameters such as Dissolved Oxygen and Suspended Solids in an Activated Sludge Plant, or pH and Turbidity at a treatment works outfall where the sensors can be located close together.
Installations can be expanded in the future if extra measurement points or parameters are required, the monitor will not need to be replaced simply add the extra hardware and re-configure the settings.
The advanced serial communication between the monitor and sensors mean the calibration and configuration data can be preserved if either part is replaced and can be copied from sensor to sensor further reducing the time required for configuration and for maintenance. The user interface on the monitor is highly intuitive, making setup and operation straightforward to carry out. This saves time and avoids the need for specialist training, most commands are self explanatory and intuitive.

The 7300w² Monitor has been designed to make our customers lives easy. The graphical display has been chosen to provide the best possible contrast, even in bright sunlight. In normal operating mode the display gives a large digit display of the measured parameter(s), the user can also select a trend display giving an indication of site performance over the last week.
The setup and maintenance menus can be accessed by pressing the menu key and following the on-screen instructions. The membrane keypad has large 20 mm keys that have a positive action allowing use of the monitor whilst wearing gloves. The use of a touch sensitive display was considered, however this idea was rejected as feedback from our customers indicated that such displays are unreliable in outdoor, arduous applications.

We offer a range of standard installation options, ranging from a simple handrail bracket, to a package including an outer enclosure, isolator and handrail mounting struts. In addition we offer a bespoke design service to ensure that our monitoring system meets the exact requirements of your site. As with all our products we can supply these options as just the hardware or provide installation and commissioning services that fully guarantee a trouble free installation.
