RS PRO Flow Meter, 2.5 L/min to 30.0 L/min


Use this flow meter from RS PRO to control the speed at which liquid passes through a mechanical system. You'll find a component like this in industrial cooling systems and it's also useful for laboratory testing. This flow sensor is suitable for water, low viscosity liquids, and opaque fluids.
The unit has chemical-resistant housing so it won't be negatively affected by aggressive and hazardous fluids, such as diesel. Its sapphire bearings are extremely resistant to shock, so the function of the flow meter remains unaffected when exposed to vibration or bumps. Sapphire also has low friction to keep the unit running smoothly. Hall-effect sensing technology ensures the meter provides highly reliable flow rate readings.
This component is well-suited to semiconductor and water treatment plants. Its IP65 (Ingress Protection) rating means it's completely protected from dust and is water-resistant.
