immediate visual feedback through the glass window, allowing quick
confirmation of flow status without additional instrumentation.
- Easy Maintenance: The front window can be unscrewed for
straightforward cleaning, minimizing downtime and ensuring
consistent accuracy by preventing debris accumulation.
- Weatherproof Design: Suitable for outdoor installations, with a
UV-resistant body that withstands harsh weather conditions,
ensuring stable performance in direct sunlight or inclement
environments.
- Versatile Application: Ideal for monitoring flow in chilled/hot
water systems, chillers, cooling/lubrication circuits, and HVAC
setups, adapting to diverse industrial and commercial flow
measurement needs.
