Environmental Controls and Instrumentation

Controls and instrumentation are critical to the efficient and safe use of material handling equipment.

Automation allows efficient integration of equipment into complex water and wastewater treatment processes and facilities. Critical process variables are monitored in real time and used to control conveyors and loading facilities. Instruments is used to protect personnel and equipment. Control stations allow for manual operation of equipment for maintenance process overrides. Plant wide control systems allow remote control of equipment in coordination with related processes and while maintaining protection of equipment and personnel.

KWS Environmental Controls and Instrumentation

KWS incorporates the following facilities into Storage and Loading Systems:

Typical Process System Application
Truck Loading Truck Scale
  • Provides real time feedback of the load in the truck. This signal is used in the control of the Loading mechanism.
  • Truck scales can be used to certify the load for legal tender.
Truck, Dumpster Loading Level Sensor System
  • Real time feedback of the level in the storage vessel, Loading vessel and/or the truck or dumpster.
Truck Loading Truck Position Sensor System
  • Used to provide guidance to the truck driver when entering the loading bay. Can be connected to a traffic light system so that the truck is positioned as required.
Conveyors – transfer, loading Local Control Station
  • Allows manual operation of the system from a location adjacent the equipment.
  • Provides an operator interface to allow input of critical data; required load, length of truck, maximum allowable level in truck, truck ID.
Truck Loading Main Control Panel
  • Can include the motor starters and interfaces to plant systems such as SCADA and related process equipment.
Conveyors – transfer, loading Motion Sensor
  • Alarms when there is a broken screw
Safety Switch
  • Interlocks with safety circuit to immediately shut down conveyor when activated by plant staff.
Torque Overload
  • Monitors conveyor motor current and voltage and triggers an over torque shutdown alarm

As a leading expert in the design and manufacture of screw conveyors, belt conveyors, truck loading systems, slide gates, bucket elevators, bins and hoppers, KWS Environmental is uniquely qualified to provide an integrated system including controls and instrumentation. The design of the controls requires a complete understanding of the mechanical equipment and the processes into which they are to be incorporated. We undertake this role on a regular basis and would be happy to collaborate with you on your next project.
