Photoelectric through-beam turbine flow meter and its cascaded application

Abstract

The invention relates to a photoelectric correlative turbine liquid flow meter. The photoelectric correlative turbine liquid flow meter comprises a casing, wherein the casing comprises a fluid conduit and a data transmission warehouse, wherein the data transmission warehouse is in bridge connection with an upper portion of the fluid conduit and covers the fluid conduit from two sides of the fluid conduit, and a correlative light path needed by a photoelectric T-R tube on a transmission control board is provided; a multi-functional front diversion rack, an impeller assembly, a diversion plug assembly and a retainer ring are sequentially arranged from a fluid inlet to a fluid outlet of the fluid conduit. According to the photoelectric correlative turbine liquid flow meter, multiple monitoring points of a water treatment system can be simultaneously monitored through a cascade liquid flow meter, a built-in micro processor of a host computer realizes information gathering, an original analysis algorithm and a digital interface are employed, the digital information including salt rejection and a dynamic waste water ratio and the state information including water leakage alarm and reversal connection indication are provided; two modes of slave computer triggering and host computer local triggering are employed, states of cascaded liquid flow meters are checked, calculation resource waste of state collection of all the slave computers carried out during regular polling of a host computer can be avoided, and communication efficiency and timeliness of a cascaded system are improved.

Description

technical field [0001] The invention relates to a liquid flow meter for comprehensive analysis and measurement of liquid and its cascade application, in particular to a cascade application of a photoelectric through-beam turbine liquid flow meter. Background technique [0002] With the development of modern technologies such as the Internet + and the Internet of Things, more quantitative requirements have been put forward for the traditional water treatment process, such as the temperature, water quality, flow rate and single treatment flow of a monitoring point flowing through the water treatment system. As well as the tracking of the processing capacity of the water treatment system, the degradation tracking and replacement reminder of key consumables, and the water leakage alarm. In order to achieve these quantitative monitoring purposes, it is generally necessary to use many discrete sensors and perform complex analysis and calculations, which not only increases the work...

Problems solved by technology

In order to achieve these quantitative monitoring purposes, it is generally necessary to use many discrete sensors and perform complex analysis and calculations, which not only increases the workload of installation and development, but also increases the risk of water leakage. Some sensors may introduce magnetic materials that are harmful to health due to limited principles.
