- The 8100 and 8200 monitors provide an exceptionally simple and reliable method of detecting the sludge blanket level in clarifiers and settlement tanks in wastewater, drinking water and industrial effluent treatment.
- The 8100 Monitor is suitable for mounting outdoors on the bridge of settlement tanks, as the enclosure is IP65 rated and no outer enclosure is required, although outer protection is often preferable to avoid degradation of the enclosure due to environmental conditions. Provision must be made for transmission of the output signal to the control system; this is normally possible via spare slip rings. Where this is not possible a radio telemetry option is available, allowing transmission directly to the control system without the need for installation of cables.
- The 8200 Monitor is a two channel version of the monitor providing the option of alarming at two positions in a tank or on two tanks that are located close together.
