Sri DIGITEK® Wireless Automatic Water Level Controller
The Sri DIGITEK® ULDX-WLS-XX is an advanced long-range RF wireless water level controller designed to eliminate long sensor wiring between distant overhead tanks and ground pumps. Operating on secure, encrypted radio frequencies, it transmits real-time tank level telemetry automatically without lightning risk, cable damage, or trenching costs.
⚙️ Key Features & Wireless Engineering
Long-Range RF Telemetry
Uses license-free, encrypted radio frequency communication (433 MHz / 868 MHz) capable of covering long distances between remote tanks and control panels without signal interference.
Zero Sensor Wiring Required
Saves expensive trenching, conduit laying, and wire replacement costs over long distances. Completely immune to lightning surges traveling through outdoor signal cables.
Automated Link Health Monitoring
The receiver continuously verifies radio contact with the overhead transmitter. If signal transmission is lost or interrupted, the system safely shuts down the pump and triggers an alarm.
Full Pump Safety Suite
Combines wireless tank telemetry with local sump dry-run protection, high/low voltage cutoffs, and power surge protection modules for complete motor safety.
Maintenance-Free AC Sensors
Employs Sri DIGITEK® SS316 stainless steel probes at both overhead and source tanks to prevent rusting, electrolysis, and salt scaling.
Solar-Powered Transmitter Option
For remote overhead tanks without electrical power outlets, an optional solar panel with rechargeable lithium battery powers the transmitter 24/7 uninterrupted.
