The RA 60 and FA 60 flowmeters operate according to the variable area (float) principle.
The measuring principle is based on a variable area flowmeter, in which the flow rate is determined by a float moving inside a calibrated tapered glass tube. The borosilicate glass measuring tube is housed in a protective steel casing with a Plexiglas viewing window.
Available versions:
| RA 60 | With threaded connection Rp ¼" to Rp 3" | |
| FA 60 | With flanged connection DN 10 to DN 200 | |
| RA / FA 60-MSK1 | With limit switch (normally closed contact) | |
| RA / FA 60-MSK2 | With limit switch (normally open contact) | |
| RA / FA 60-MSKW | With changeover limit switch | |
| RA / FA 60-EM* | With 4 ... 20 mA analog output* (Available only for size 100 and size 110 models.) |

| RA / FA 60... Ex | Explosion-proof version |
MSK1 / MSK2 / MSKW Limit Switches
These flowmeters can be equipped with a magnetic float and bistable electrical reed contacts, adjustable across the entire measuring range.
4 ... 20 mA Output
The linear position sensor, based on the Hall effect principle, provides an output signal proportional to the float position. The signal can be supplied as a 4 ... 20 mA or 0 ... 10 V output for remote indication purposes. The sensor is connected via the supplied M12 × 1 mm connector.
