NJ-025G.080 Flow Indicator
The NJ-025G.080 flow indicator is part of the Senseca / Honsberg NJ/NJV range of mechanical flow indicators for liquid media. It uses a spring-supported piston and magnetic coupling to move the indicator ring. As a result, the flow reading can be displayed mechanically.
It is designed for water flow monitoring. The brass body has a G1 female process connection (DN25) and a listed display range of 20–80 L/min.

Applications
This mechanical flow indicator can be considered for industrial liquid circuits, machinery, circulation lines and process systems that require a local flow reading. However, final suitability depends on the medium, pressure, temperature, flow rate and installation conditions.
Installation and selection
The standard installation is vertical, with flow from bottom to top. In addition, the manufacturer recommends a straight calming section of 5 × DN at both the inlet and outlet. If the liquid contains contamination, install a suitable filter.
Before ordering, confirm the liquid, flow direction, required display range and whether an electrical switching contact is needed. For NJV oil models, also provide the viscosity and operating temperature.
