The NJ and NJV Flow Indicators from PVL Ltd provide dependable flow measurement and switching for water and oil-based systems, including dark or contaminated media. Featuring a spring-supported piston and magnetically coupled display, the meter remains free from contamination while ensuring high visibility and durability. Available in brass or stainless steel, these robust devices suit a wide range of applications.
The NJ is ideal for water, while the NJV is viscosity-compensated for oils (30–200 mm²/s). Both models offer flow ranges from 2 to 80 l/min, operate up to 100 bar, and withstand media temperatures from –20°C to +100°C. Multiple switch contact options (reed or mechanical) and connection sizes (DN8 to DN25) support flexible installation. Designed for vertical flow (other positions possible), the NJ/NJV range offers accuracy, reliability, and adaptability in demanding environments.
