Leave a messageMeasurement principle:
The product uses a dual-mode sensor that combines radar Doppler and ultrasonic Doppler to sense water flow velocity, and then uses a combination of radar, static pressure, and conductivity sensors to sense water level changes, in order to calculate real-time flow rate of manholes.
Doppler ultrasonic flowmeter brings you professional service,the design intention of this product is low operation and maintenance volume. In the scenario of manhole flow, it fully utilizes the advantage of non-contact flow measurement of radar, reduces the probability of sensor hanging, and supplements the flow velocity perception at high water levels through ultrasonic connection measurement. Multi sensing can enable products to complement each other's strengths and weaknesses, making them more suitable for working conditions.
Main features:
▶ Dual mode flow velocity sensing (ultrasonic and radar waves), seamless docking (no blind spots);
▶ Pay attention to the boundary conditions of flow velocity: 0.2m/s~0.3m/s (non-contact radar flow velocity sensing);
▶ Multi mode perception of water level (radar, static pressure, and conductivity);
▶ Output parameters: comprehensive flow rate, comprehensive flow rate, comprehensive water level;
▶ Other parameters: single-mode flow rate, flow rate, water level, and sensor status;
▶ The top of the horizontal pipe is installed, and wellhead operations can be achieved through brackets;
▶ The host adopts an alloy plastic shell, which has anti-corrosion, waterproof, and impact resistance properties;
▶ Sealed with glue, not afraid of the impact of temperature changes on the seal;
▶ Supports RS485 upgrade and can achieve remote OTA with full host configuration;
▶ Installation at the top of horizontal pipelines can effectively prevent sensor hanging;
▶ The installation bracket can facilitate the fixation of sensors.
