  • Page 42: Wet Well Control (Pump Down)

    WET WELL CONTROL (Pump Down) Typically, wet wells are used to temporarily hold storm and/or waste water. When the surface reaches a high level setpoint, the wet well is pumped down. The discharge goes on to another wet well or directly to the treatment facility. The HYDRO+ provides wet well control with only minimal application programming.

  • Page 44: Reservoir Control (Pump Up)

    RESERVOIR CONTROL (Pump Up) Typically, reservoirs are used to temporarily hold processed water. When the water surface reaches a low level setpoint, the reservoir is pumped up. The HYDRO+ provides reservoir control with only minimal application programming. For the following example, we’ll assume Empty (P006) was set from the transducer face to the reservoir bottom.

  • Page 46: Rake Control (Differential Level)

    RAKE CONTROL (Differential Level) Typically a water purification process has a screen on the inlet side to filter solids from entering the process. Should the screen become blocked, and inflow sufficiently reduced, process efficiency can often be compromised. The HYDRO+ provides screen rake control with only minimal application programming.
