Ex Concept Recognised World-wide
Optimum safety, especially in explosion hazardous areas, is a necessity for todays measurement and control technology.

The Ex de concept, with explosion proof electronics and increased safety outputs (optional intrinsically safe) enables safe and reliable operation in Zone 1 areas. The cable connections between the transmitter and sensors are also intrinsically safe.

Advantages at a Glance
Operation without opening the housing, even in hazardous areas
World-wide approvals for Ex Zone 1 areas
Ex de explosion protection
ATEX approval available immediately

High Process Integrity
Prosonic Flow has standard additional functions which continually monitor the fluid and the process.

Different fluids are recognised immediately by the permanent measurement of fluid-specific speed of ultrasonic sound. In addition the transmitter can operate two measuring points simultaneously. This opens up further application areas such as plant balancing, leak detection, etc. The configurable relay outputs guarantee additional operational safety.

Advantages at a Glance
Permanent monitoring of product quality
Electronics with self-monitoring and alarm function
Configurable relay outputs (limit values, flow direction, etc.)
