Abstract

The invention relates to an installation, flow measurement and maintenance method of an open channel ultrasonic flowmeter, which is suitable for measuring water in tail-section lateral channels and field channels of irrigation areas, and belongs to the technical field of application of ultrasonic flowmeters. According to the technical scheme, a transducer (6), a liquid level meter (7), an integrating module, a battery pack and a remote transmission module are arranged on the box wall of a culvert box (5), the culvert box (5) is installed in a culvert groove or a culvert and positioned, and upstream canal water flows to the downstream after passing through the culvert box (5) in the culvert groove or the culvert; the transducer (6) and the liquid level meter (7) on the culvert box (5) detect flow velocity and water level signals flowing through the culvert box (5), and flow information is uploaded through the remote transmission module after the flow velocity and water level signals are converted by the integrating module. The method has the advantages that battery power supply can be achieved, the transducer can be conveniently taken out under the condition that the canal wall is not broken or dismantled, canal bank land does not need to be occupied, a power supply system is simplified, and the maintenance and repair construction amount is reduced.

Description

technical field

[0001] The invention relates to an installation flow measurement and maintenance method of an ultrasonic flowmeter in an open channel, which is suitable for measuring water in bucket canals and agricultural canals at the end of irrigation areas, and belongs to the technical field of ultrasonic flowmeter applications. Background technique

[0002] At present, the known open channel ultrasonic flowmeter is composed of a converter, a transducer (probe), a liquid level gauge, a power supply system and a remote collector. During installation, the transducer is poured into the channel, and the power supply system, remote collector, liquid level gauge and converter are suspended on the bank of the channel through solar poles. However, the power supply system needs to build a foundation on the canal bank, and the land on the canal bank needs to be occupied; after the transducer is poured, the maintenance and repair of the transducer needs to be demolished. Wall, was...
