Measurement Principle:
A sensor that utilizes a composite dual-mode radar and ultrasonic Doppler sensor to detect water flow velocity, and then combines radar, static pressure, and conductivity sensors to perceive water level changes, thereby calculating the real-time flow rate of manholes.
Low maintenance volume is the design philosophy of this product. In situations like manhole flow, it maximizes the advantages of radar non-contact flow measurement to reduce the probability of sensor material adhesion, and supplements flow sensing during high water levels with ultrasonic measurement. Multiple sensors allow the product to complement each other's strengths, making it more suitable for operational conditions.
Key Features:
▶ Dual-mode flow sensing (ultrasonic and radar waves), seamless (no blind spots) connection;
▶ Note flow velocity boundary conditions: 0.2m/s ~ 0.3m/s (non-contact radar flow sensing)
▶ Multi-modal water level sensing (radar, static pressure, and conductivity)
Output Parameters: Comprehensive flow rate, comprehensive flow, comprehensive water level.
▶ Additional Parameters: Single-mode flow rate, flow, water level, and status of all sensors.
Top-mounted horizontal pipe, with brackets for wellhead operations.
The main unit is housed in an alloy plastic shell, featuring corrosion, waterproof, and shock-resistant properties.
▶ Sealed with potting compound, unaffected by temperature changes on the seal.
▶ Supports RS485 upgrade, with the entire host, it can achieve remote OTA.
Top-mounted horizontal pipeline installation, effectively preventing material adherence to sensors.
▶ The installation bracket facilitates the secure mounting of the sensor.
Application Scenarios:
Culvert flow measurement sensors, suitable for culvert velocity, water level, and flow remote sensing.
