Portable Ultrasonic Open Channel Flow Meter

1. Product Introduction:

The portable open channel flowmeter is a high-precision measuring instrument designed for hydrological monitoring, river flow monitoring, agricultural irrigation, municipal water supply and drainage and other industries. It uses ultrasonic technology and a special micro-power design scheme, combined with full digital signal processing technology to ensure the stability and reliability of the measurement. The device has a wide measurement range and high measurement accuracy, supports real-time data display, data recording, export and printing, is easy to operate and highly accurate, and is very suitable for occasions that require frequent movement for measurement. At the same time, it is based on the JJG711-1990 verification procedure, and refers to the relevant requirements for flow monitoring units in HJ353-2019, HJ354-2019, HJ355-2019 and HJ15-2019 for comparison and acceptance, ensuring its applicability and accuracy in water conservancy projects, environmental monitoring, agricultural irrigation and other fields.

2. Application scope:

Water conservancy engineering department: monitor the water flow velocity and flow rate of rivers, channels and reservoirs;

Environmental protection departments, water quality monitoring stations and related environmental protection enterprises: use such equipment to monitor the flow rate and flow rate of urban drainage systems and industrial wastewater discharge;

Third-party testing agencies: on-site calibration and comparison of online open channel flowmeter equipment;

Emergency management departments: quickly evaluate water flow conditions and provide data support for flood control and disaster reduction.

3. Implementation standards:

JJG711-1990 "Open channel weir flowmeter";

HJ15-2019 "Technical requirements and detection methods for ultrasonic open channel sewage flowmeter";
