Smart wireless ultrasonic level transmitter enables real-time tank level monitoring through 2.4G WiFi wireless communication. It supports remote data transmission within a 50 m wireless range and helps reduce installation costs by removing the need for traditional wiring. With low sensor power consumption of ≤100mA at 5V DC and high measurement accuracy of ±0.02 m, it is suitable for smart water management, industrial automation, and remote monitoring systems.
Cloud Remote Liquid Level Monitoring
- Real-time tank monitoring: Track liquid level anytime via the life APP to avoid unexpected water shortage.
- Custom upper and lower thresholds: Set max & min liquid level freely to prevent tank overflow or depletion.
- Instant mobile alert notifications: The ultrasonic level sensor pushes reminders once liquid level exceeds preset limits for unattended remote management.
Field Installation & Industrial Adaptability
- Equipped with a 4m extended cable, flexible mounting for vertical storage tanks and elevated water towers.
- IP65 dustproof & waterproof housing, stable operation in outdoor environments to sustain long-term tank monitoring.
Applications
WiFi ultrasonic level sensor enables remote liquid level monitoring and tank monitoring, ideal for rooftop water tanks, elevated water towers, and industrial liquid storage tanks with neutral liquid. It is not suitable for oil media or solid materials.

Installation Notes
Install the wireless ultrasonic level sensor perpendicular to the liquid surface.
Mount the ultrasonic level sensor transmitter away from the water inlet to prevent false echoes.
Do not install the ultrasonic level sensor close to the tank wall; otherwise, strong false echoes will occur.
Installation Method
Q1: What is a wireless ultrasonic level sensor?
A1: A wireless ultrasonic level sensor is a non-contact device that uses ultrasonic waves and wireless communication to measure liquid levels remotely. It sends ultrasonic signals to the liquid surface, calculates the distance based on echo time, and transmits level data through 2.4G WiFi without additional signal wiring.
Q2: How far can a WiFi ultrasonic level sensor transmit data?
A2: This wireless ultrasonic level sensor supports 2.4G WiFi communication with a transmission distance of up to 50 m without obstacles. The actual wireless range may vary depending on walls, interference, and installation conditions.
Q3: Why choose a wireless ultrasonic level sensor instead of a wired level sensor?
A3: A wireless ultrasonic level sensor is easier to install because it reduces the need for long cables between the sensor and monitoring system. It is especially useful for locations where wiring is expensive, difficult, or inconvenient.
Tips: What is the difference between a wireless ultrasonic level sensor and a traditional ultrasonic level sensor?
The main difference is the communication method. A wireless ultrasonic level sensor uses WiFi communication to transmit level data without additional signal cables, making installation easier in locations where wiring is difficult. A traditional ultrasonic level sensor requires wired connections for data transmission. Both use non-contact ultrasonic measurement technology, but wireless models provide more flexible installation and convenient remote tank level monitoring.
