Product Description

Welcome to Jiangsu Aice Instrument Technology Co., Ltd., a leader in precise and innovative instrumentation solutions.

Product Description

1. INTRODUCTION

The Ultrasonic Open Channel Flowmeter by Jiangsu Aice Instrument Technology Co., Ltd. is an advanced, non-contact instrument that leverages the principle of acoustic reflection to measure water levels in weirs, ultimately calculating the flow rate. This sophisticated device consists of an ultrasonic probe and a mainframe, both encased in a fully sealed plastic structure. Widely applicable in industrial and environmental protection domains, it provides accurate flow measurements for open channels. The probe is mounted above the weir, intermittently emitting ultrasonic waves towards the water surface. Upon reflecting back, these waves are captured by the probe, and the main unit measures the time of propagation, t. Utilizing the pre-determined weir type, the main unit then calculates the precise flow rate based on the detected liquid level.

Installation Instructions

I. Basic Setting Once the instrument is installed, simply configure the installation height and select the appropriate standard weir/flume type along with its respective instrument settings. II. Installation Height Setting The installation height varies with different types of water measuring weirs/flumes. Below are guidelines for setting the installation height for several standard types: 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 Choose the standard flume/weir type according to the actual type in use. Different types of flumes/weirs require setting specific geometric parameters. Below are the necessary geometric parameters for several common flumes/weirs: Parshall Flume: Select 'Parshall Flume' as the flume type and set the standard flume number. The width of the throat section of a Parshall flume determines the flume number, as detailed in Table 1. Rectangular Weir: Select 'Rectangular Weir' as the flume type and configure the channel width, weir width, bottom height, and the geometric parameters of the rectangular weir.
