without being present at the monitoring site and allows the user remote access to those data at any
time. Telemetry is helpful in deciding when a trip to the field for multiprobe calibration or
maintenance is necessary. Telemetry is also ideal in locations for which access is dangerous or
expensive.

On-Line Monitoring, also known as process-control monitoring, means that the multiprobe is
connected to a PLC, SCADA system, etc. An example is monitoring the input to a water-treatment
plant for salinity or chlorophyll. On-Line Monitoring allows the user to make water-quality-based
decisions in real-time. The Manta is particularly effective in this application when more than one
parameter is used in the control loop.
B.4 Underwater Cables
The later Manta Underwater Cables have a marine-style connector (left), while the early Manta
Underwater Cables had an audio-style connector (right).
Vented Underwater Cables, which are used with the optional Vented Level sensor, have a small tube
within the VUC to connect the sensor to the surface of the water so that changes in barometric pressure
do not affect level readings. That vent tube is connected to a desiccant pack at the top of the VUC to
prevent water from condensing inside the vent tube. Later VUC’s are fixed to the Manta and cannot be
removed.
