The U707 is a compact PTFE liquid flow sensor featuring a straight flow path for inline fluid connections and a pulse 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 10 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 10 L/min.
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 it’s compact size and affordable cost, McMillan’s Model U707 Flow Sensor is 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 1 – 10 L/minute are available. Consult the factory or an authorized representative for custom requirements.
Model U707 units features a straight flow path, which allows all fluid connections inline with existing plumbing for simple installation.
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 U707 units feature a pulse output.
Pulse output models have an accuracy specification of ±3.0% full scale (including linearity).
All units have PTFE male flare connections as standard.
All units come standard with a 7-Pin connector. Options available for a integrated FEP-jacketed cable terminated with pigtail leads.
