EX-FLOW

Mass Flow Meter/Controller for gases in hazardous areas

These intrinsic safe EX-FLOW instruments are suitable for use in Zone 1 and comply with ATEX, IECEx, TIIS and KCs standards. The EX-FLOW is available as both a meter and a controller. With their rugged and industrial-style (IP65) design, the EX-FLOW gas flow instruments are a good fit for industrial applications. Especially in the chemical industry, fuel cell technology, gas distribution systems, hydrogenation processes and biogas production processes.

01—04

Accuracy ★★★☆☆

The stainless steel capillary sensor offers a good accuracy with good temperature stability.

02—04

Certified for use in hazardous areas

EX-FLOW is certified for hazardous areas zone 1 and has several certifications, including ATEX, IECEx, TIIS and KCs certificate.

03—04

Suitable for non-inert (reactive) gases

"EX-FLOW instruments can handle reactive gases offering greater versatility, making them suitable for a wide range of applications in laboratories."

04—04

Flow control by integrated or close coupled control valve (optional)

The PID controller in the electronics unit (located in the safe area) maintains a steady flow rate without the need of an external PLC.
