HydroLERT Level Alarm Systems - COMING SOON
Simple, visible alarm protection for tanks, sumps, and process applications.
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
