Overview

Ultrasonic open channel flowmeter is a system monitoring device used to measure fluid flow in open channels or channels. The open channel flowmeter monitoring system is suitable for measuring the flow of rectangular and trapezoidal open channels and culverts in reservoirs, rivers, water conservancy projects, urban water supply, sewage treatment, agricultural irrigation, water management and water resources. In recent years, it has been widely used.

超声波明渠流量计

Ultrasonic open channel flowmeter for water flow measurement equipmentfeature

Large measurement range, flow measurement is not affected by the backflow of tributaries.

During measurement, the flow sensor is not affected by floating sediment, bubbles, and significant changes in water level. It has a simple structure, small volume, and easy installation, which can cause resistance to water flow.

Standard channels do not require modification and can be installed directly, with low installation and construction costs.

The instrument display output function is complete, which can display measurement data such as water level, flow rate, flow rate, and cumulative flow rate, and has RS-485 communication interface.

◆ It has the function of water level, mud level, and flow rate exceeding the limit alarm.

◆ It has data saving function, which can save the set parameters and flow values in case of long-term power outage.

Advantages of Ultrasonic Open Channel Flow Meter Technology

Open channel flow meters are different from other closed full pipe flow meters in that they are flow meters with free surface flow in non full pipe conditions or open channels. The open channel flowmeter based on the open channel principle is widely used in open channel flow measurement due to its low cost and simple operation.
