The product employs a dual‑mode measurement approach combining ultrasonic and hydrostatic sensing. At medium and low water levels, it leverages the non‑contact ranging capability of ultrasound to detect water level, effectively handling conditions involving water quality, suspended solids, and floating debris. At high water levels, it automatically switches to a hydrostatic sensor mounted at a higher position, using pressure to measure the water level and thereby overcoming the ultrasonic blind zone that arises under elevated conditions. This composite sensor design simultaneously addresses both the ultrasonic blind zone and the issues of clogging and atmospheric pressure influence inherent in hydrostatic measurements, making it one of the most reliable measurement solutions available today. Moreover, the two sensor systems can cross‑calibrate each other, further enhancing measurement stability. In particular, this system excels in urban manhole‑level monitoring applications.
The product employs hydrostatic and immersed (conductivity‑based) sensors to measure water level. It supports multiple power supply options, including external power and a self‑powered mode (the standard model, which is recommended for self‑powering). It can transmit acquired water level data or elevation data to a server via a reliable 4G wireless connection.
The product employs hydrostatic measurement, using a pressure sensor to detect the water level. When taking measurements, it is important to address potential issues such as blockage of the sensor’s pressure port or pressure chamber, as well as the influence of atmospheric pressure. In practical applications, regular maintenance and cleaning are essential.
Radar level gauges use millimeter-wave signals operating in FMCW mode to measure the distance to reflecting objects. Millimeter-wave radar continuously emits a continuous wave whose frequency varies with time; when the signal encounters a reflector, it is reflected back. By comparing the frequency difference between the transmitted and received signals, the distance between the reflector and the radar can be calculated. Microstrip antenna array technology is employed to ensure measurement precision and accuracy.
