Measuring applications with the flowtherm Ex are manifold: gas mass flow and flow rate in air, exhaust air, process gases, particle and condensate laden emissions, vehicle exhaust emissions, in aggressive gases with high working temperatures and, most importantly, in the hazardous area Zone 1, et al.

ATEX-approved for potentially explosive atmospheres:  II 2G Ex ib IIC T4

That is why the new handheld flowtherm Ex lends itself especially for measuring on gas blow-outs and in gassing of utility gas pipelines, in hazardous areas of all industrial branches, municipal utilities and public authorities as well as for research and development.

Measurements with up to three sensors can be displayed simultaneously.

The data logger allows storage of up to 40,000 values with date and time.

Up to 100 different profiles can be stored for user or measuring points.

Various measurement modes (also long-term measurement).

Thanks to the USB interface, the logged data can be downloaded to a PC for configuration.

The flowtherm Ex has the following inputs: flow sensors (VA, FA, TA); Pt100; 4-20 mA; 0-10 V.

A 12 V supply is available for sensors in 4-wire system.

Mains or battery operation.
