Installation Instructions

1. Remove the release paper from the gasket and place it at the center of the tank where you plan to drill.
2. Drill a circular hole with a diameter of 55mm–80mm at the center of the tank lid or top panel.
3. Place the sensor over the gasket, aligning it with the screw holes and ensuring the sensor face is clear of obstructions.
4. Secure the sensor in place using the included self-tapping screws.

Pre-Installation Tips: Position the sensor vertically above the liquid surface. Install away from tank inlets to avoid false echo readings. Avoid mounting near internal bulkheads or partitions.

Note: This Zigbee version requires a compatible Zigbee gateway hub (not included) for wireless connectivity. Colors may appear slightly different due to monitor settings. Allow 1–2 cm variance due to manual measurement.

Frequently Asked Questions

Q: Does the WiFi ultrasonic water tank level sensor require a gateway?

A: Yes, this model uses Zigbee 3.0 wireless protocol, which requires a compatible Zigbee gateway hub to connect to your WiFi network and smartphone app. The gateway is not included in the package.

Q: What types of tanks is this ultrasonic level sensor compatible with?

A: This sensor is suitable for a wide variety of tank types, including plastic, fibreglass, concrete, and metal water tanks. It works for rooftop water storage, underground cisterns, agricultural tanks, and light industrial containers — any tank where the sensor can be mounted vertically above the liquid surface.

Q: How accurate is the ultrasonic water level measurement?

A: The sensor provides measurements with an accuracy of ±0.02 meters (±2 cm) across a range of 0–5 meters, making it precise enough for everyday household and light commercial water management needs.

Q: Is this sensor waterproof enough for outdoor installation?

A: Yes. The sensor carries an IP65 waterproof rating, meaning it is fully protected against dust ingress and low-pressure water jets from any direction, making it well-suited for outdoor tank installations in varied weather conditions.
