Function
The warning device monitors the status of
n
a fat level sensor or
n
an overflow sensor or
n
the combination of an overflow sensor and a fat level sensor
in a grease interceptor.
LEDs at the device indicate alarm, sensor fault and system and sensor status. In
the event of an alarm, an additional acoustic signal sounds.
The fat in the grease interceptor can be of various compositions. The following
conditions are possible:
n
The fat is liquid. Such fat is found in, e. g., the manufacture and storage of
vegetable fats. This fat forms a liquid fat layer which clearly separates from
water. For this composition of fat, please use fat level sensor KVF-F for
detecting the fat layer thickness.
n
The fat is hard. Such fat is found in, e. g., waste water from sinks or
dishwashers and in floor drains in large kitchens or catering
establishments. This fat consists of a mixture of animal and vegetable fats.
It typically forms an aqueous emulsion with small lumps of fat or a
hardened layer of fat. For this composition of fat, please use fat level
sensor FAU-104 for detecting the fat layer thickness.
