These flowmeters in AISI316L are suitable for medium and high flow rates.
They are suitable for any kind of liquid even at high pressures and temperatures.
They are available with only the local indicator of capacity, with microprocessor technology - two wires, with 8-digit LCD display suitable for measure the flow rate, totalized and percentage, with output signal 4 to 20 mA, Hart (power supply: 24Vdc ± 10%).
They can be fitted with a valve adjustment 316L and / or self-regulating differential flow BL AISI316L.
On request, they are also ATEX certified EEx ia IIC T6, Zone 0 and Zone 1.

The materials of construction of these Variable Area Flowmeter are AISI 316L stainless steel (other materials upon request) to the measuring tube, and connections to all parts in contact with the process fluid.
The outer casing is cast aluminum, epoxy painted, or in AISI 316 (on request).
There are versions with lining measuring tube made of PTFE with flanged connections for heavy duty versions and versions with float free, for fluids with suspended solid particles.
There are accessories such as heating jacket with connections ½ "NPT-F or flanged, alarm signal minimum or maximum capacity (inductive Namur, CENELEC approved intrinsically safe EEx ib IIC T6 or NPN relay), power pack for sensors also intrinsically safe.
