How To Install A Water Level Indicator

Installing a water level indicator can be a straightforward DIY project or a more technical job, depending on the type of system (mechanical, float-based, sensor-based, or electronic). Below is a general step-by-step guide for installing a basic electronic water level indicator system for a standard overhead tank.

🧰 What You’ll Need:

• Water level indicator kit (includes sensors, control unit, wires, and possibly a display)

• Power drill

• Waterproof silicone or sealant

• Electrical tape

• Screwdriver

• Cable clips or zip ties

• Ladder (if the tank is elevated)

🪜 Step-by-Step Installation Guide

✅ 1. Turn Off Power

Always start by turning off the main power supply if you’re working with electrical devices.

✅ 2. Mount the Control Unit

• Choose a dry, accessible location near the tank or inside your house (depending on the model).

• Mount the control/display unit on a wall using screws.

✅ 3. Install Sensor Probes in the Tank

You typically need 3 to 5 probes (depending on your system), which measure:

• Empty/Low level

• Middle level

• Full/High level

• (Optional) Overflow or critical low

How to install:

• Drill small holes on the tank lid or side wall near the top.

• Insert the probes or float sensors to the corresponding depths (use the manual to know the exact position).

• Seal around the holes using waterproof silicone to prevent leakage.

• Secure the sensor wires with cable clips inside or along the tank body.

✅ 4. Connect Wires to the Control Unit

• Use the labeled diagram in your kit’s manual to match each sensor wire to its terminal.

• Typically, wires run from each sensor to a central controller unit via color-coded terminals (e.g., red = full, yellow = mid, green = low).

• Use electrical tape to secure connections and prevent short-circuits.

✅ 5. Test the System

• Turn the power back on.

• Slowly fill the tank and monitor the display or indicator lights.

• The control unit should light up or beep as water reaches each sensor level.

✅ 6. Optional: Connect to Pump

If your indicator supports pump automation:

• Connect the pump’s power relay to the controller as instructed.

• The system will automatically turn the pump on when water is low and off when full.

🔒 Safety Tips:

• Always use waterproof-rated wires and connectors.

• Keep control units protected from rain and moisture.

• Don’t overtighten sensors; water tanks expand slightly when filled.

🛠️ Types of Systems You Can Install:

Our level sensors and controls aren’t just for use in residential potable water holding tanks; some of the other applications include cooling towers, sump pumps, wastewater, boilers, water storage tanks, and building fire protection water tanks.
