• Direct reading on a calibrated tube • Water: Up to 16 m³/h ; Air: Up to 160 m³/h • Body: Stainless steel • Adjustable limit value switches • Analogue output: 4-20 mA or 0-10 V • ATEX version
Direct reading of flow rates of liquids and gases: - Water treatment, Industrial process (paper mill, textiles etc.), chemical and pharmaceutical industries
The 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 tube is inside a stainles steel protection case with a transparent reading window. These flowmeters can be calibrated for each fluid, depending on the operating conditions.
Standard versions: RA 87 G Fittings: BSP-F ¼'' ... 2'' RA 87 Rp Fittings: Unions FA 87 Fittings: Flanges ND 10 ... 65 RA / FA 87-MSK1 With bistable contact N.C. RA / FA 87-MSK2 With bistable contact N.O. RA / FA 87-MSKW With bistable changeover contact RA / FA 87-EM With analogue output 4-20 mA or 0-10 V RA / FA 87.Ex ATEX, explosion-proof version
Limit value switches These flowmeters can be equipped with a magnetic float and Reed contacts, triggerpoints adjustable over the entire measuring range.
Analogue output 4-20 mA or 0-10 V The transmitter is connected to a Hall effect linear signal ruler. The analogue signal (4-20 mA or 0-10 V) is the image of the float position; The transmitter is connected via a connector M12. This output is useful for applications using a PLC. The device is compact with a high level of repeatability.
