 Principe |
Direct measurement and visualisation of flow rate of gases and liquids: water treatment, industrial processes (paper, textiles, etc.), chemical and pharmaceutical industries, heating or cooling circuits.
The measuring principle is that of a variable area flowmeter, in which a float moves inside a calibrated conical glass tube. The borosilicate glass cone is housed in a protective steel tube with a viewing window. These flowmeters can be calibrated for each liquid depending on operating conditions.
Available versions:
| RA 87 G | with female thread G ¼" to G 2" | |
| RA 87 Rp | with two-piece pipe union | |
| FA 87 | flanged connection DN 10 to DN 65 | |
| RA / FA 87-MSK1 | with limit switch (normally closed contact) | |
| RA / FA 87-MSK2 | with limit switch (normally open contact) | |
| RA / FA 87-MSKW | with changeover contact | |
| RA / FA 87-EM | with 4–20 mA analog output | |
| RA / FA 87... Ex | ATEX explosion-proof version |
LIMIT SWITCHES
These flowmeters can be equipped with a magnetic float and electrical reed contacts, adjustable across the entire measuring range.
4–20 mA ANALOG OUTPUT
The output is generated using a linear Hall-effect sensor. This sensor produces an analog signal representing the float position and is connected via an M12 connector. Due to its compact design and high repeatability, this output is particularly suitable for integration of an analog signal into a PLC system.
