Pulsar Measurement – DFS 5.1 – Clamp-On Doppler Ultrasonic Flow Switch (Non-Contact, For Difficult Liquids)

The DFS 5.1 Doppler Flow Switch is a valuable tool for pump protection and flow or no-flow alarms. It offers basic process control for pipe flow measurement, especially for challenging liquids like wastewater, slurries, chemicals, and more. This non-contacting ultrasonic sensor is easy to install on metal or plastic pipes without disrupting flow, increasing efficiency. With no maintenance needed, it works on pipes 12.5 mm or larger, with adjustable flow rate settings and the ability to set separate ON/OFF points or high/low flow alarms using relays.
