BAMO RA60/FA60’S measuring principle is that of the variable area flowmeter, the float is moved by the fluid inside a calibrated conical glass tube. The borosilicate glass conical is inside a steel case with a transparent reading window.
Versions:
- RA60 Fittings: Unions BSP-F: ¼” to G 3”
- FA60 Fittings: Flange ND 10 to ND 200
- RA/FA60-MSK1: With N.C. bistable contact
- RA/FA60-MSK2: With N.O. bistable contact
- RA/FA60-MSKW: With bistable changeover contact
- RA/FA60-EM: * With analogue output 4-20 mA or 0-10 Volt (Only on model sizes 100 and 110)
- RA/FA60-Ex: ATEX, explosion-proof version
Contacts: These flowmeters can be equipped with a magnetic float and Reed contacts, trigger points adjustable over the entire measuring range.
Output 4-20 mA or 0-10 Volt: The transmitter is connected to a Hall effect, linear signal ruler. The analogue signal is the image of the float position. The transmitter is connected via an M12 connector. This output is useful for applications using a PLC. The device is compact with a high level of repeatability.
