Float arrester - TC-ME
The TC-ME float arrester prevents sensor drifting or transport by water currents, while permitting its free vertical
displacement with rising or falling water levels.
The MicroApolarm™ system is not designed for operation in fast-flowing water or strong wind, and should not be
used in such circumstances.

The MicroApolarmTM oil leak detection system is
designed for optimum performance in small
indoor or underground drain pits for conduits or
channels.
It comprises a floating-body hermetically-sealed
capacitance sensor (CS-1505) and a signal
converter (AS-15) for power supply, signal
conversion, and alarm activation. The CS-1505
sensor circuit applies a high-frequency potential
to three electrodes which project downward from
the float body.
If an oil layer forms on the water, and the
electrodes thus project into oil rather than water,
it effectively lowers the capacitance between the
electrodes and ground. This change is detected,
amplified, and conveyed as a signal current from
the sensor circuit via the sensor cable to the AS15 signal converter, which then engages the oil
leak alarm circuit.
