Product Description

1. INTRODUCTION

Our Ultrasonic Open Channel Flow Meter is a cutting-edge, non-contact device harnessing the principle of acoustic reflection to precisely measure water levels over weirs. This innovative meter comprises a robust ultrasonic probe and a durable mainframe, both encased in a fully-sealed plastic structure. It excels in both industrial and environmental applications, delivering accurate open channel flow detection. The ultrasonic probe, strategically positioned above the weir, periodically emits ultrasonic waves towards the liquid surface. These waves are reflected back to the probe upon hitting the liquid surface, and the main unit measures the propagation time (t). By identifying the weir type, the host accurately determines the flow rate based on the liquid level.

Installation Instructions

I. Basic Setting Once the instrument is installed, simply set the installation height and select the appropriate standard weir/flume type for operation. II. Installation Height Setting The installation height varies with different types of water measuring weirs/flumes. Below are the standard methods to confirm installation heights for several 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 in 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 in the measuring weir, in meters.
III. Flumes/Weirs Selection and Setting Corresponding Geometric Parameters Select the standard flume/weir type based on the actual type of flume/weir in use. Set the corresponding geometric parameters according to the selected type: Parshall Flume: Choose 'Parshall Flume' and set the standard flume number based on the width of its throat section, as detailed in Table 1. Rectangular Weir: Choose 'Rectangular Weir' and set the channel width, weir width, bottom height, and other geometric parameters specific to the rectangular weir type.
