Core Technology

PULSE Technology

Traditional water level sensors pass a constant DC current through water, which causes electrolysis — splitting the water molecules and corroding the sensor probes over time. ELPRO's PULSE technology completely eliminates this problem.

1
Pulsed Signal — Not Continuous

Instead of a steady DC current, PULSE technology sends short electrical pulses to sense water conductivity — no continuous current flow means zero electrolysis.

2
Longer Sensor Life

Probes last significantly longer with no corrosive electrolytic action — reducing maintenance costs and sensor replacement frequency.

3
Accurate Level Detection

Clean probes mean consistent conductivity readings — no drift or false triggers caused by corroded probe surfaces.

Why ELPRO

Smart Water — Less Waste

ELPRO water management products protect your motor, extend sensor life and ensure water is always available when you need it.

PULSE Sensing

Pulsed current sensing prevents electrolysis on sensor probes — no corrosion, no false readings, longer sensor service life.

Dual Tank Logic

ULTIMAN models monitor both overhead and underground tanks simultaneously — motor runs only when underground has water and overhead needs filling.

MCU Based

Microcontroller technology delivers precise level detection, reliable switching and consistent performance across all operating conditions.

Dryrun Prevention

When the underground tank runs dry, the controller stops the motor automatically — protecting your pump from dry-run damage.

4 Sensor Types

LLC-ULTRA supports SS, Carbon, Magnetic and Float switch sensors — works with whatever sensor type your installation already uses.

Star-Delta Ready

ULTIMAN-415 has an inbuilt Star-Delta timer — directly compatible with 3-phase DOL and Star-Delta motor starters without extra timers.

Sensor Compatibility

Sensor Types Supported

Choose the right sensor for your tank type, water quality and installation requirements.

SS (Stainless Steel) Sensors

Corrosion-resistant probes for clean and slightly hard water. Long life in open sumps and overhead tanks.

LLC-ULTRA
Carbon Sensors

Non-reactive carbon probes ideal for hard water or areas with high mineral content. No rust or corrosion.

LLC-ULTRAWLC-110
Magnetic Sensors

Reed switch based contactless sensing. No probe contact with water — ideal for sealed tanks or corrosive liquids.

LLC-ULTRA
Float Switch

Mechanical float switch input. Works independently of water conductivity — reliable in any liquid type.

LLC-ULTRA
PULSE Conductivity

Built-in pulsed conductivity sensing in ULTIMAN models. No external sensors needed — just dip the probe wires.
