Video alarm system

The video alarm system from Longwatch, a division of IVC, brings operators the complete picture by incorporating alarm-based video directly into the operator screens. Video clips are recorded when alarm conditions from the SCADA system or from cameras are triggered at the remote site. The alarm with video clip attached can then be viewed over the Web, through email, on cellphones or directly in the SCADA/HMI system.

Once operators see the alarm video clip and message on the HMI screen, they can command the system to transmit live video and remotely pan, tilt and zoom the site cameras to further investigate process or intrusion alarms. 781/255-7400;


Lift station control panel

The ECO SMART STATION from SJE-Rhombus provides a safe, simple, energy-efficient solution for pump control in municipal lift stations. It integrates the Energy View controller with variable-frequency drive technology into the multiple-compartment enclosure to reduce exposure to arc flash and save energy. The color touch screen HMI can provide level control, pump alternation, flow monitoring, data logging, alarm log, and historical trending.

The auto-tuning function searches for the Best Efficiency Frequency (BEF). When the pump operates at the BEF point, it uses the least energy per gallon pumped. During high-low conditions the software can automatically switch to PID operation for optimum energy efficiency and resume cycle based operation when normal flow returns. 888/342-5753;
