Product Description

1. INTRODUCTION

The Ultrasonic Open Channel Flowmeter from Jiangsu Aice Instrument Technology Co., Ltd. is an advanced non-contact device that leverages the acoustic reflection principle to precisely measure water levels in weirs. This sophisticated instrument, comprising an ultrasonic probe and a robustly sealed mainframe, is tailored for industries and environmental applications to ensure accurate open channel flow detection. The ultrasonic probe, strategically mounted above the weir, emits periodic ultrasonic waves toward the liquid surface. These waves reflect back to the probe upon reaching the surface, and the mainframe calculates the propagation time (t) of this process. Leveraging the pre-determined weir type, the mainframe then computes the flow rate based on the liquid level, offering unmatched precision and reliability.

Installation Instructions

I. Basic Setting Once the instrument is installed, simply set the installation height and select the standard weir/flume type for seamless operation. II. Installation Height Setting The installation height varies with different types of water measuring weirs/flumes. Below are standard methods for determining installation height: Parshall Flume: Measure the vertical distance from the end of the ultrasonic transducer (probe) to the bottom inside the flume in meters. Rectangular Weir: Measure the vertical distance from the end of the ultrasonic transducer (probe) to the lowest point of the weir's water outlet in meters. Triangular Weir: Measure the vertical distance from the end of the ultrasonic transducer (probe) to the right-angle point of the weir's water outlet in meters.
III. Flumes/Weirs Selection and Setting Geometric Parameters Choose the actual type of flume/weir and set the corresponding geometric parameters as follows: Parshall Flume: Select 'Parshall Flume' type and set the standard flume number based on the width of the throat section. Refer to Table 1 for the standard flume number based on measured throat width. Rectangular Weir: Choose 'Rectangular Weir' type and configure the channel width, weir width, bottom height, and geometric parameter descriptions accurately to ensure optimal functionality.
