Ultrasonic open channel flow rate comprehensive monitoring instrument and measuring method thereof

Abstract

The invention discloses an ultrasonic open channel flow rate comprehensive monitoring instrument and a measuring method thereof, belonging to the field of metering. The monitoring instrument comprisesan underwater measuring equipment and an abovewater control equipment which are connected with each other by a cable, wherein the control equipment sends measurement command to the measuring equipment; the measuring equipment is used for detecting the flow rate and the liquid level and transmitting the results to the control equipment; and the control equipment stores and displays the received results. The specific steps of the method are explained in specification. The invention utilizes ultrasonic Doppler principle to measure the flow rate and ultrasonic transit-time method principle to measure the liquid level, and can simultaneously measure the water temperature. The invention can modify the working parameters of the instrument at any time, avoids the occurrence of siltation and blockage fault of sensors, displays the current working state timely, alarms in time when finding the fault, is beneficial to reducing the power consumption, and is applicable to measuring rivers or channels with wider widths; furthermore, an split-type ultrasonic wave sensor and a temperature sensor lead independent debugging to be easier, thus being easy to realize standardized production. The invention can be applied to metering the flow rate of open channels, rivers and the like.

AI Technical Summary

Benefits of technology

This patented technology uses an improved design that reduces energy usage by controlling various devices within submerged structures while still being able to detect issues quickly enough without having them shut down completely. It also includes features like separating signal processing from communication between different components (control unit), reducing noise interference caused when signals are transmitted through cables connecting sensors together, allowing remote monitoring capabilities, simplifying assembly processes, improving safety measures, etc., making it more efficient than traditional methods such as monitors placed directly above each other's surface.

Problems solved by technology

This patents discusses various technical problem addressed during designing and operation of monitoring systems for open channels like streams where there may occur flooding events caused by heavy rain falls over short distances between adjacent points. These issues affect accurate measurements made about these locations because current solutions require multiple steps involving separate devices and involve expensive materials. There is therefore a demand for more efficient and reliable closed channel flow surveying techniques without compromising their effectiveness against flood conditions.
