The U702 is a PTFE liquid flow sensor featuring a U-shaped flow path for compact fluid connections and an analog output. McMillan U70X Series Flow Sensors are capable of measuring extremely low flow rates of high-purity or corrosive media. Units are available that measure liquids as low as 13 mL/min and as high as 50 L/min.

McMillan U70X Series Flow Sensors are capable of measuring extremely low flow rates of high-purity or corrosive media. Units are available that measure liquids as low as 13 mL/min and as high as 50 L/min. Full scale accuracies of ± 1.0% or better are available on analog output models.
A wide variety of liquids may be measured. Repeatable results are achieved using a patented Pelton-type microturbine wheel. This proven design has been providing precision results since 1988 and has developed a well-deserved reputation for continuous operational service for many years without failure.
Because of their robust design and precision measurement capability, McMillan’s Model U70X Series are suitable for a wide variety of industrial, commercial, laboratory and OEM applications. PTFE, FFKM, and Sapphire wetted parts ensure compatibility with chemicals commonly found in microelectronics manufacturing processes, including deionized water, CMP slurries, acids, solvents, and photoresist.
Flow ranges from 13 – 100 mL/minute up to 5 – 50 L/minute are available. Consult the factory or an authorized representative for custom requirements.
Model U702 units feature a U-shaped flow path, which allows all fluid connections on one side of the unit to effectively reduce footprint.
Most units may be specified to operate with either 12 VDC or 24 VDC power. Various power adapters are also available for use with 12 VDC versions.
Model U702 units have multiple options available, including 0-5 VDC, 0-10 VDC, and 4-20 mA output.
Analog output models have an accuracy specification of ±1.0% full scale (including linearity).
All units have PTFE male flare connections as standard.
All units have an integrated FEP-jacketed cable terminated with pigtail leads.
PTFE, FFKM, and sapphire wetted parts ensure compatibility with chemicals commonly found in microelectronics manufacturing processes, including deionized water, CMP slurries, acids, solvents, and photoresist.
McMillan has a comprehensive range of remote displays for use with U70X Flow Sensors. For further information, please contact the factory or an authorized representative.
