Overview

HydroLERT® is a compact and versatile alarm controller designed to detect one or two alarm conditions using digital switches or a conductivity probe. It provides clear local audible and visual warning for level, pressure, flow, temperature, and other limit-alarm applications.

WHY CHOOSE HydroLERT
  • Two configurable inputs and selectable operating modes support flexible single- or dual-level monitoring.
  • Early warning helps reduce the risk of tank or sump overflow.
    Low-level warning can help protect pumps and systems from dry-run conditions.
  • Audible buzzer and high-visibility strobe provide clear local alarm indication.
  • Mute and hold-to-test functions make local operation and routine testing simple.
  • Flexible sensor compatibility supports float, pressure, temperature, and flow switches, plus conductivity sensing.
BUILT FOR PRACTICAL INSTALLATIONS
  • Compact IP65-rated ABS enclosure for wall or pole mounting.
  • Adjustable alarm delay from 2 seconds to 18 minutes.
  • Voltage-free BMS/common-fault output and 12 Vdc remote buzzer output.
  • Battery-backup model keeps alarm capability available during mains power loss.
  • Suitable for new installations and retrofit applications across water, wastewater, irrigation, and process systems.
COMMON APPLICATIONS
  • Water storage tanks
  • Pump stations and sumps
  • Wastewater and stormwater systems
  • Irrigation and rural water systems
  • Chemical and process tanks
  • Pressure, flow, and temperature limits
  • Commercial and industrial facilities
PAIR WITH
  • Float switches for high-, low- or critical-level alarm points
  • Conductivity probe for liquid-level detection
  • Pressure switches
  • Temperature switches
  • Flow switches
  • Remote buzzer for additional alarm indication
