Safety instructions
1.1 Software history
1.2 Intended use
The OPTISYS SLM 2100 sludge level meter is primarily designed for use in water and waste
water treatment plants. There it determines the sedimentation profile in clarifiers and sludge
thickeners and detects sludge blanket or fluff level. For this it measures the suspended solids
concentration and height of the sensor above ground as the sensor is lowered into the basin or
tank.
However, the design of the OPTISYS SLM 2100 makes it possible to use it in other applications
where reliable monitoring of interface or stratification in suspensions is necessary.
The OPTISYS SLM 2100 shall not be used in hazardous areas, which e.g. require Ex approvals. It
could ignite gases. Additionally, due to the sensors material, the meter shall not be used in
applications with a high concentration of salt (e.g. seawater). The device has been constructed
for indoor and outdoor use below the maximum altitude of 2000 m / 6562 ft.
By observing the operation instructions, national standards, safety requirements and accident
prevention regulations the residual risk is reduced to an acceptable level.
