YSLUVortex Flowmeter
Smart Vortex Flowmeter
Smart Vortex Flowmeter measures liquid, gas and steam flow using Karman vortex principle with piezoelectric detection. It covers nominal diameters DN15–300 mm (pipe section) and DN200–2000 mm (insertion), media temperature -20 to 350 ℃, accuracy class 1.0/1.5, and provides voltage pulse or 4–20 mA output. Typical applications include petroleum, chemical, power and heating industries.

YSLU questions
What ranges are available for the YSLU?
Standard coverage is Liquid 0.27–9 m/s; gas 4–40 m/s; steam 3–50 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 YSLU 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 YSLU from qualified partners, inspect before shipment, and handle export documents and logistics.
Need the right smart vortex flowmeter for your process?
Send the medium, range, output, and quantity. We will confirm the matching option and a FOB Ningbo quote.
