Overview
Ultrasonic flow velocity and liquid level meters can measure the flow velocity of rivers and open channels, directly connected through a digital communication interface. Doppler flow velocity meters provide simple, reliable, and cost-effective on-site sensor monitoring data, and have remote status display, calibration, setting, and fault diagnosis functions. IP68 rated dust-proof and waterproof sturdy shell, 1500N high-strength Kevlar cable, with a maximum transmission distance of over 1.2 kilometers, can be directly installed in application environments such as reservoirs, rivers, tap water, and sewage.
