Product Details

The GCF-M series ultrasonic time-difference open channel flow meter is a high-performance ultrasonic flow meter independently designed and developed by our company. Based on the time-difference measurement principle and using an open structure, this flow meter is suitable for accurate flow measurement in main and branch streams of water conservancy and irrigation areas.

The product includes an ultrasonic flow measurement unit and a radar level unit. By using layered velocity and level data, it accurately measures water flow. The product can also easily connect to RTUs, lithium batteries, solar chargers, etc., to achieve storage and real-time upload of water level and flow data. The product has high measurement accuracy, high reliability, and simple maintenance.

Features

Wide measurement range: Measurable range of ±0.01m/s-±5m/s
Reliable transducer structure: Smooth water flow, not easy to accumulate debris, reliably withstands floods to avoid damage
High stability: Integrated data processing algorithm, water flow state, impurities, and accumulation have no effect on the results
Strong scalability: Connecting RTU, lithium battery, and solar charger for convenient power supply and real-time data upload
Industrial-grade reliability: Key components use high-performance, high-reliability industrial components for a long service life
Accurate measurement: Low-noise measurement circuit combined with flow state fitting algorithm, measurement error within the full range is less than the standard requirement
Easy installation: Customized production according to the site environment, on-site calibration-free, no wiring required, configuration can be completed via mobile phone Bluetooth
Simple equipment maintenance: Supports remote status detection, equipment upgrades, and fault diagnosis; it can also be maintained via on-site Bluetooth connection

Application Areas

Open channel and gate flow measurement and monitoring in water conservancy, agriculture, and irrigation areas
Flow measurement and monitoring of urban drainage
