- AOSL66 Ultrasonic Open Channel Flowmeter
◆Measuring principle
When liquid passes through measuring flumes such as Parshall flumes, triangular weirs, and rectangu
lar weirs, different head heights are formed at varying flow rates. The instrument utilizes a non-contact ultr
asonic ranging method to obtain the head height, which is then converted into the corresponding flow rate
based on standard algorithms—a measurement approach.
◆Main Characteristics
▶Measurement parameters: water level, flow rate, cumulative flow degree
▶Adaptable to commonly used: Parshall flume, triangular weir, rectangular weir, etc.
▶Applicable standards: JJG711-1990 and HJ15-2019
▶The host is a wall-mounted aluminum casing
▶Optional sound velocity self-calibration rod accessory
▶Built-in history query function
▶Backlit Chinese LCD display
▶Fully Chinese operation menu
▶Optional wireless output configurations: 4G, NB-IOT, LORA (AUTEC protocol)
▶Awarded: Multiple patents and software copyrights
▶Obtained: the "CCEP China Environmental Protection Product Certification
Certificate" issued by the China Environmental Industry Association (Beijing)
Certification Center;
▶Obtained: "CMA Testing Report" from the South China Institute of Environmental
Sciences, Ministry of Ecology and Environment;
▶Obtained: "Inspection Report" from the Quality Supervision and Inspection Testing
Center for Hydrological Instruments and Geotechnical Engineering Instruments of the
Ministry of Water Resources;
▶Selected into the "National Key Procurement Catalog for Bidding Products in Water
Conservancy Systems"
Application Environmental discharge outlet monitoring, agricultural water measurement, water intake
scenarios:measurem ent, surface water runoff flow measurement, and other open-channel, non-full
pipe sedimentation m onitoring.

Note2 For 1~4# Parshall Flumes, Right-angled Triangular Notch Thin-plate Weirs, and Rectangular Weirs, M48X2 is usually selected for process connections; for 5~25# Parshall Flumes, G2A is usually selected for transducer process connections. Note3 For 1~4# Parshall Flumes, Right-angled Triangular Notch Thin-plate Weirs, and Rectangular Weirs, 100K flared mouth transducers are selected; for 5~25# Parshall Flumes, 64K transducers are selected. Note4 The standard cable length of the transducer is 10 meters. If other lengths are required, they shall be noted separately when placing an order; on-site self-extension is not supported.When the cable length is extended, please refer to Table 1* to select transducers with the corresponding range.
