ACCRESSORY :
- The limit reed switch ZE 95 / ZE 951 serves as a flow signal transmitter. It is clamped to the dovetail guides and signals when the magnetic float in the measuring tube has reached or passed the signal transmitter position. As soon as this happens, a contact in the signal transmitter, as the actual switching element (reed switch), opens or closes.
- Accessory for the flow meter, type DFM with a magnetic float
- Simple assembly and positioning on the dovetail of the DFM measuring tube
- Plug of the compact reed switch can be positioned in 0° – 90° – 180° steps
- Easy to retrofit in existing systems
