Tokyo Keiso NLZ series Metal Tube Type Variable Area Flowmeter
Made in Japan
Manufacturer: Tokyo Keiso
Model: NLZ Series
The NLZ series is a compact, metal tube type variable area flow meter with a face-to-face dimension of 250 mm.
This series consists of NLZ1000 (general type and intrinsically safe type) and NLZ2000 (flameproof type). Each model has various types including a local indication without power supply type and a field bus type. The NLZ series can measure flow rates of any processes and devices.
The standard material for the wetted parts is 316L stainless steel.
Fluor resin lining is also available for highly corrosive fluids. As optional indicator and transmitter functions, alarm output, 4–20 mA DC output, HART® communication, and FOUNDATION® Field bus can be added. The NLZ series has acquired JPN, ATEX, IECEx, NEPSI, and KOSHA explosion proof certifications.
Features
- The face-to-face dimension is unified to 250 mm for all connection sizes from 15 mm to 100 mm, which allows for easy piping design.
- Intrinsically safe construction: NLZ1000 series
- Flameproof construction: NLZ2000 series
