- AOW910W IoT Water Level and Water Temperature Meter
Measurement principle
The product measures pressure by leveraging the piezoresistive effect of diffused silicon—specifically, a Wheatstone bridge fabricated on a single-crystal silicon wafer using photolithography and diffusion techniques along a defined crystal orientation. By incorporating laser trimming and computer‑based compensation algorithms, its temperature performance has been significantly optimized. Moreover, sensors have rapidly evolved from analog to digital designs, resulting in improved overall stability and reliability.
The transmission cable incorporates an internal gas conduit that delivers atmospheric pressure to the front-end sensor’s voltage‑multiplier chamber, thereby compensating for atmospheric pressure variations.
Key Features
- Integrated structure, available in standard analog and intelligent versions;
- Explosion-proof specifications: intrinsically safe (requires use with an input safety barrier), flameproof;
- Equipped with a patented anti-clogging attachment;
- It can simultaneously monitor both water level and water temperature.
- Digital sensor;
- Supports the heavy‑hammer installation method;
- The IoT version is self-powered and supports wireless connectivity options such as 4G and NB‑IoT.
Application scenarios
Suitable for level measurement in municipal, hydrological, industrial settings, chemical storage tanks, wastewater treatment plant ponds, and other similar applications.
