Flow Switches

Flow Switches

A flow switch is a tool used to start and stop an electric current in a circuit, just like all other switches. A flow switch is crucial for monitoring and managing the flow rate of process media, such as steam, liquids, and gases, in an industrial system. Flow switches activate actions in multiple machines throughout a system to offer on/off flow control of process media, helping to maintain safe and controlled rates of flow. 

  • <h2>PF3A, Digital Air Flow Sensor, 2-Screen 3-Color Display, IP65, 30-12000 Lpm</h2><p><h3>Series PF3A digital flow switch provides continuous quantitative values as well as switched digital outputs when set flow levels are measured. The PF3A is suitable for applications requiring a metered quantity of air, such as for supply confirmation, filling accumulation, or fixed supply consumption. The oversized PF3A display has 2 screens, with main screen flow values in red or green, while the sub screen settings are shown in orange. The display can be rotated in 90 degree increments, thereby offering better visibility during operation. The thermal sensor is protected in a bypass flow path to reduce contact with moisture and contaminants, avoiding accuracy deterioration and damage. The PF3A has an IP65 ingress protection rating and is both RoHS and CE compliant.</h3>- Applicable fluids: Air, Nitrogen<br>- Flow ranges: 30-3000, 60-6000, and 120-12000 liters/min<br>- Rated Pressure: 0.1 to 1.5 MPa<br>- Accuracy: +/-3.0% F.
