Xinye XY-6900A Portable Open Channel Flow Meter APP Version

1、 Technical background and application

In order to implement the Environmental Protection Law of the People's Republic of China and the Water Pollution Prevention and Control Law of the People's Republic of China, protect the ecological environment, and safeguard peoplePhysical health, and2019year12moon24On the day, the "Online Monitoring System for Water Pollution Sources" was released（CODCrTheNH3-N wait）Installation TechnologyStandardization and Online Monitoring System for Water Pollution Sources（CODCrTheNH3-N wait）Acceptance Technical Specifications. In the 'Installation Technical Specification', it is proposed toIn the composition of the online monitoring system, a flow monitoring unit is required. For the discharge units that need to measure the flow, a standardized metering weir for open channels should be built

(Slot)）And the construction of the weir should be able to conduct comparison work of open channel flow meters. It is recommended to use triangular weir, rectangular weir, and Bacher trough. In the 'Acceptance Techniques'In the "Technical Specifications", specific requirements are proposed for the acceptance method of water pollution source flow monitoring units, which are divided into liquid level error comparison and flow error comparison

According to the above requirements, it can be seen that portable open channel flow meters are required for on-site acceptance, and continuous statistical records should be kept during the acceptance processLiquid level data and flow data need to be provided in12Synchronize recording of online open channel flow meters and portable sewage flow meters within minutes6A liquid level data, and in

10Synchronize recording of online open channel flow meters and portable sewage flow meters within minutes2Accumulated data of open channel flow, and because the sewage flow has been monitoredCheng is irreversible. Once there are problems during the recording process, it is necessary to conduct a new comparison and acceptance, and provide on-site verification in both time and spaceCollecting work has brought difficulties.

In response to the current lack of portable sewage flow meters in China that can easily and quickly complete the above acceptance tasks, our company utilizes multiple methodsYears of experience in developing environmental monitoring instruments, combined with the 'Online Monitoring System for Water Pollution Sources'（CODCrTheNH3-N wait）Installation Technical Specifications "and" Online Monitoring System for Water Pollution Sources "（CODCrTheNH3-N wait）Acceptance Technical Specifications "and《HJ 15-2019Technical requirements for ultrasonic open channel sewage flowmeterDevelop a portable open channel flowmeter that meets the on-site acceptance requirements for flow meters based on the technical and functional requirements outlined in the "Exploration and Testing Methods"Flowmeter.

This portable open channel flow meter is mainly used for on-site technical parameter evaluation and acceptance of online open channel sewage flow meters, and can also be extended to flow measurement of open channel sewage discharge in enterprises.
