In the fields of water management, environmental monitoring, and agricultural irrigation, open channel flow meters are key equipment for accurately measuring water resources. Zhuomai InstrumentsupplyOpen channel flow meters, with their three core advantages of non-contact measurement, multi parameter integration, and strong environmental adaptability, have become popular in urban water supply, sewage treatment, and agricultural irrigation scenarios“Traffic Guardian”This provides reliable technical support for efficient management of water resources.

Technological breakthrough: Non contact measurement solves traditional pain points

Traditional open channel flow meters often use contact measurement, and sensors that are immersed in sewage for a long time are prone to corrosion or blockage, leading to increased measurement errors and even equipment damage. Zhuomai InstrumentSupply ofThe innovation of open channel flowmeter adopts ultrasonic or radar non-contact measurement technology, which calculates the liquid level height by emitting sound waves or electromagnetic wave reflection time, and then combines it with the water level of measuring weir slots (such as Bacher slots and triangular weirs)-The traffic relationship model indirectly calculates channel traffic. This design completely avoids direct contact between sensors and sewage, avoiding corrosion and scaling problems, especially suitable for sewage environments containing sediment, chemical pollutants, or corrosive media.

For example, in the monitoring of sewage discharge in a chemical industrial park, traditional contact flow meters frequently malfunction due to chemical corrosion, while Zhuomai instrumentsSupply ofThe open channel flowmeter, with its non-contact characteristics, has been running continuously and stably for over two years, reducing maintenance costs70%.

Function upgrade: Multi parameter integrated construction of monitoring network

Zhuomai InstrumentSupply ofThe open channel flowmeter not only focuses on flow measurement, but also constructs a comprehensive water environment monitoring system through data storage and multi instrument access functions. The device is equipped with a large capacity storage, which can record traffic data and connect to other instruments (such as...)CODThePHDissolved oxygen water quality sensor4-20mASignal to achieve synchronous monitoring of flow and water quality parameters. Data can be viewed locally through buttons, output on-site through printers, or accessed throughRS-232TheRS-485TheGSMRemote transmission through SMS and other means, supporting environmental protection departments to real-time grasp the situation of enterprise sewage discharge or optimize the process flow of sewage treatment plants.

After adopting this equipment in a sewage treatment plant in a certain city, the flow data is compared with the inflowPHWater outletCODCorrelation analysis accurately identified the efficiency bottleneck of the biochemical treatment unit, improving the water discharge compliance rate to98%.

Scenario adaptation: Full coverage from urban water supply to agricultural irrigation

Zhuomai InstrumentSupply ofThe modular design of open channel flow meters enables them to flexibly adapt to different scene requirements. In urban water supply channels, equipment can be paired with Bacher troughs to achieve high-precision measurement; In agricultural irrigation channels, a right angled triangular weir can be selected to adapt to low flow scenarios. Its non-contact characteristics make it an ideal choice for harsh environments such as cooling water channels and sewage treatment discharge channels in thermal power plants. In addition, the device supports a multi-point flow velocity measurement system, which connects multiple flow velocity meters and liquid level meters through a flow display instrument to synchronously monitor the flow distribution of wide cross-section channels such as reservoirs and rivers.

Zhuomai InstrumentSupply ofThe open channel flowmeter has redefined the method of water resource measurement through technological innovation. Its non-contact measurement technology solves the durability problem of traditional equipment, the multi parameter integration function improves monitoring efficiency, and the scenario adaptation capability expands the application boundaries. With the deepening of smart water conservancy and environmental protection supervision, this equipment will continue to assist in the refined management of water resources and inject technological momentum into green development.
