This water level detector is a fully automated online hydrological monitoring system based on microwave technology. It employs K-band planar radar technology for non-contact water level measurement, with a ranging range of 0.1 to 40 meters and an accuracy of ±5 millimeters. It is suitable for scenarios such as rivers, irrigation canals, and flood warning systems, and the measurement is unaffected by temperature, sediment, and floating debris.
The water level detector is a fully automated online hydrological monitoring system based on microwave technology, primarily used for water level measurement in rivers, irrigation canals, underground drainage networks, and flood warning systems. This device uses K-band planar radar technology to measure water levels non-contactly, calculating and outputting real-time water level data based on built-in software algorithms. Compared to traditional contact water level gauges, radar water level gauges do not require the construction of water level wells, resulting in lower civil engineering investment. They can be installed using a cantilever bracket, making installation convenient.
In terms of technical performance, the water level detector has a ranging range of 0.1 to 40 meters, a ranging accuracy of ±5 mm, a ranging resolution of 1 mm, and an interval time that can be freely set between 1 and 5000 minutes. The device is powered by a combination of solar panels and batteries, with selectable solar power of 10W or 30W. The battery parameters are DC 3.7V 10Ah. The support frame height is 3 meters for the upright and 3 meters for the crossarm. The operating ambient temperature range is -45°C to 85°C (non-freezing condition). The device's signal output adopts the RS485/MODBUS protocol, and its outdoor protection rating reaches IP68.
The water level detector has several advantages in practical applications. First, the non-contact measurement method, combined with cross-sectional parameters, calculates flow rate, unaffected by factors such as wind, temperature, fog, silt, and floating debris. Second, the device is suitable for various measurement conditions, unaffected by corrosion and foam, and can output water level and rainfall measurement data. Furthermore, the water level detector uses a planar array radar antenna with built-in angle measurement function; the device is compact and easy to install. The device also supports a client-server (CS) architecture software platform, allowing users to directly observe data via mobile phone or PC browser without additional software installation. It supports multiple accounts and devices for login, real-time and historical data display dashboards, SMS alarms, and threshold settings.
The water level detector has a wide range of applications, covering water level measurement in rivers, lakes, tides, reservoir gates, underground water pipe networks, and irrigation canals. It assists in water treatment operations such as urban water supply and sewage monitoring, as well as flow calculation and inflow/outflow monitoring. At the manufacturer level, Shandong Fengtu IoT Technology Co., Ltd.'s FT-SW1 model water level detector is a radar water level gauge, with a reference price of 16,000 yuan. With the continuous improvement of the automation level of hydrological monitoring, radar-based water level detectors are gaining increasingly widespread application due to their non-contact, high-precision, low-power consumption, and maintenance-free characteristics.
