Product Description

1. INTRODUCTION

The Ultrasonic Open Channel Flowmeter is a cutting-edge, non-contact device that harnesses the power of acoustic reflection principles to precisely monitor water levels in weirs and convert these measurements into accurate flow rates. This sophisticated instrument comprises an ultrasonic probe and a mainframe, both featuring a fully sealed plastic structure. Widely applicable in industrial and environmental sectors, the device excels in accurately gauging open channel flows. Mounted above the weir, the ultrasonic probe periodically emits ultrasonic beams towards the liquid surface. These beams are reflected back to the probe, and the mainframe calculates the propagation time (t) of the ultrasonic waves. By correlating this data with predefined weir types, the mainframe determines the exact flow rate based on the liquid level measured.

Installation Instructions

I. Basic Setting After the installation of the instrument is completed, you simply need to set the installation height and choose the standard weir/flume type along with its corresponding instrument for seamless operation. II. Installation Height Setting Installation height varies based on the type of water measuring weir/flume. Below are methods for confirming installation heights for standard water measuring weirs/flumes: Parshall Flume: Measure the vertical distance from the end of the ultrasonic transducer (probe) to the bottom inside the water measuring flume, in meters. Rectangular Weir: Measure the vertical distance from the end of the ultrasonic transducer (probe) to the lowest point of the water outlet of the measuring weir, in meters. Triangular Weir: Measure the vertical distance from the end of the ultrasonic transducer (probe) to the right-angle point of the water outlet of the measuring weir, in meters.
III. Flumes/Weirs Selection and Setting of Corresponding Geometric Parameters Based on the actual flume/weir type, select the appropriate standard type and configure the corresponding geometric parameters. Below are the geometric parameters required for common flumes/weirs: Parshall Flume: Select the flume type as Parshall Flume and set the standard flume number. The width of the throat section in a Parshall Flume determines the flume number. Refer to Table 1 for the measured throat width to select the standard flume number. Rectangular Weir: Choose the flume type as Rectangular Weir and set parameters including channel width, weir width, bottom height of the rectangular weir, and descriptions of the rectangular weir geometric parameters.
