The Delta HLA Plus Intelligent is supplied with a Delta Level Float and is compatible with all Delta V3, V4 and V6 groundwater / surface water pumping stations. It can also be retrofitted to any existing groundwater / surface water pumping station.

Delta HLA Plus Intelligent is a highly advanced high water level alarm monitoring system. The Delta Level Float transforms the Delta HLA Plus ('smart' high water level alarm) into an 'intelligent' high water level alarm, not only detecting when a high water level occurs in a sump pump chamber, it also monitors sump pump activity - number of activation(s), and changes in sump pump activation(s) (both frequency and duration).

This additional information allows for real-time calculation of flow, volumes of discharge over given periods, and changes in level of activity within the pumping station including decline in pump performances.

The Delta HLA Plus Intelligent has both proactive and preventive functions. Real-time analysis of a pumping station enabling service, maintenance or repair requirements to be detected and implemented at the earliest stage.

Key features

  • Proactive and preventive functions

  • Instant real-time monitoring to spot service failures before they make any impact

  • Records frequency of sump pump activation(s)

  • Records duration of sump pump activation(s)

  • Records fixed depth of water being evacuated from sump pump chamber

  • Records fixed volume of water being evacuated from sump pump chamber – based on pump chamber diameter

  • Records and monitors pump activities within pump stations

  • Sends notification messages to users in real time:
    – if there is mains power outage
    – when a high-water situation has been recorded
    – when a high-water level situation occurs
    – when a service or routine maintenance is due
    – when changes in pump activity occur (frequency and duration)

  • Visual and audible displays on the HLA Plus Device

The Delta HLA Plus features three volt-free (dry) contacts for connection building management systems. They can be configured to Normally Open (NO) or Normally Closed (NC) depending on requirements.
