- Low-cost Mass Flow Meter with Indicator
MODEL 3810DS SERIES - The low-cost mass flow meter products
The KOFLOC Low-Cost Mass Flow Meter MODEL 3810DS SERIES is based on the well-received 3810 SERIES. It is a low-cost mass flow meter with an optional needle valve, which can replace more expensive mass flow controller in many applications. It is designed with focus on low-cost, accuracy and adaptability.
KOFLOC MFM MODEL 3810DS SERIES
Quick Review
• Low-Cost
The design of the KOFLOC Low-Cost Mass Flow Meter MODEL 3810DS SERIES is based on the time-tested MODEL 3810 SERIES. When used with the optional precision needle valve, it can serve as a low-cost alternative to more expensive mass flow controllers, especially in applications where attaining the optimum flow requires expert tweaking that cannot easily be simulated by rougher control offered by common MFCs.
•The KOFLOC Precision Needle Valve MODEL 2412 SERIES
The KOFLOC Precision Needle Valve MODEL 2412 SERIES is a high-performance needle valve with non-rotating needle with excellent temperature characteristics. It is especially suited for fine control of minute flow.
•KOFLOC Dependability
KOFLOC has 60 years of experience in manufacturing precision flow instruments. KOFLOC products, both standard and off-catalog custom items are well received throughout Japan as the name that manifests confidence. KOFLOC, the fluid expert, is the name professionals trust in precision control of minute flow.
• Digital Flow Indicator
The KOFLOC Low-Cost Mass Flow Meter MODEL 3810DS SERIES is a mass flow meter. It requires no temperature or pressure dependant compensations or tedious calculations. The flow can be read directly from the digital flow Indicator, or output signal.
•Adaptability
The KOFLOC Low-Cost Mass Flow Meter MODEL 3810DS SERIES is a light, compact unit requiring a single DC24V power source. With 2 alarm setting, digital indicator, output signal and use of SUS316L or Teflon® wetted parts, along with Viton® o-rings all makes this unit highly adaptable, including Rohs compliance.
