Micronics UF DS200 | Clamp-on Doppler Flow Switch | 12.5 mm–4.5 m Pipes, 0.075–3 m/s Set Points
The Micronics UF DS200 is a non-contacting Doppler flow switch for liquids that carry bubbles or solids, such as sewage, sludge, slurries, acids, caustics, abrasives and viscous liquids. Its ultrasonic sensor straps to the outside of metal or plastic pipes from 12.5 mm to 4.5 m ID and can be fitted while the system is running, with no drilling and no pressure drop. It is typically used for pump protection, high or low flow alarms and overfill control.
Key features
- Separate ON and OFF set points from 0.075 to 3 m/s, or Hi/Lo flow alarm mode
- 5 A DPDT relay with adjustable 0–80 s time delay to prevent chatter
- LED bargraph for flow rate and set points, plus relay status LED
- Stainless steel sensor housing, no moving parts and no sensor maintenance
- Self-tunes to sensor cable extended up to 150 m
- Switch-selectable normal and failsafe modes
