Flow Meters
YSQDUltrasonic Flowmeter
Ultrasonic Doppler Flowmeter
Measures flow velocity (0.03–10 m/s, ±1% or ±0.010 m/s), flow rate, water level (0–10 m, 0.5% FS) and water temperature (0–60 °C, ±1 °C) in open channels, rivers, sewage pipelines and industrial wastewater. RS-485 Modbus and 4-20 mA outputs; used for pollution source monitoring, industrial process water and municipal/industrial sewage treatment.
- Velocity measurement accuracy
- Relative error ±1%, absolute error ±0.010 m/s
- Flow velocity range
- 0.03–10 m/s
- Power supply
- 9–36 VDC
- Water level range
- 0–10 m
- Long-term automatic detection with compact structure and strong environmental adaptability
- Cross-sectional flow velocity measurement with minimal impact on water flow state
- Doppler frequency shift algorithm provides stable measurement and millimeter-level velocity resolution
- Real-time water depth and water temperature detection in addition to flow rate
- IP68 protection for full/non-full pipes and river channels with turbidity >20 NTU

YSQD questions
What ranges are available for the YSQD?
Standard coverage is 0.03–10 m/s. Other spans, outputs, and process connections can be sourced to match the application. Send the working pressure and medium and we will confirm the exact option.
What is the MOQ and lead time?
1 pc (flexible, no minimum for most products). 2-3 days for in-stock items, 15-30 days for custom orders. Samples are available, with freight on the buyer’s account.
Can the YSQD be customized?
Range, output signal, process connection, cable length customizable through our supply partners.
Do you manufacture this transmitter?
SIBXSUN is an industrial instrumentation supplier in Ningbo, not the factory. We source the YSQD from qualified partners, inspect before shipment, and handle export documents and logistics.
Need the right ultrasonic doppler flowmeter for your process?
Send the medium, range, output, and quantity. We will confirm the matching option and a FOB Ningbo quote.
