Made in Japan
Manufacturer: Nippon Flow Cell
Model: NSP

This is an area flow meter that achieves short delivery times by standardizing the fluid and flow rate range.

For Vertical Piping
NSP-1 Type	NSP-1G Type (Flange Connection)
For Panel Mounting
NSPO-4 Type
For Horizontal Piping
NSP-5 Type (Flow Direction: Left → Right) NSP-6 Type (Flow Direction: Right → Left)	NSP-7 Type (Flow Direction: Left → Right) NSP-8 Type (Flow Direction: Right → Left)

Features

• By standardizing fluids and flow rate ranges and maintaining stock, we have achieved shorter delivery times.
• The flow direction options include vertical piping (bottom to top), panel mount type (bottom to top), and now the lineup has expanded to include horizontal piping (left to right or right to left) with a unique design.
• For vertical piping, the NSP-1G type with flange connection is also available.
• Ordering: Please select from standard flow rates and scale numbers (for liquids (water equivalent) and gases) based on your usage conditions. We will provide the scale number upon request, making it easier for customers to place orders.
• For liquids (water equivalent), the flow rate units are L/min (or mL/min) and t/h (or m³/h). For gases, the standard flow rate is represented by double scales for N2 gas, and standard configurations for other gases are available. Rc1/4 – 4 models can also accommodate gases like Air, Ar, or CO2 (single scale available for each).
• The main materials used are stainless steel or PVC, with resin-coated pipes having excellent corrosion resistance. Additionally, flange connection models (NSP-1G type) with acrylic tubes or resin pipes can also be manufactured.
• We are open to manufacturing custom specifications (for different fluids or flow ranges), so feel free to consult with us.
