Basic description of the AXsensor’s measurement of liquid levels for distribution
All electronics outside the tank
- Wireless connection
- Alarms mobile, tablet or computer
- Simple installation – plug’n’play
- No external power supply
- Measures up to the tank top
- SLS – Sonic Level Sensing
- Robust real-time measurement
- Works for most liquids
The liquid level monitor AXsensor uses an acoustic pulse with low frequency and extremely low power consumption. The AXsensor is powered by batteries with a running time of 3-10 years. All electronics are outside the tank and the AXsensor transmits an acoustic pulse, through a measuring tube (waveguide) to the surface of the liquid, which measures the time calibrated for temperature. The AXsensor has a built-in antenna that communicates using the LoRa (LPWAN) and Sigfox network.
The AXsensor is mounted on the top of the tank
Most important benefits
- Smart, simple and robust
- Reliable, maintenance-free and cost-effective
- Easy installation, wireless connection without cable installation – plug’n’play
- IoT (Internet of Things) – Cloud service that can be read on mobile, tablet or computer
- Measures all the way up in the tube/tank roof (no dead band)
- Reliable measurement even in foam and turbulence. Nor is it disturbed by physical obstacles (stag / tubes / beams)
- The length of the measuring tube is completely adaptable
- No need for calibration during installation
