Heinrichs Messtechnik GmbH For horizontal and vertical installation • Extreme robustness due to guide stars instead of rod guides • Suitable for all flow directions • Flow measurement of liquids and gases • Outstandingly clear reading due to 90° arranged scale • Electrical transmitter with HART® or Fieldbus Foundation® • Suitability for installation in safety-related measuring systems according to SIL Technical Information BGF Errors and technical modifications excepted.

Heinrichs Messtechnik GmbHFunction The measuring element consists of a sharp-edged measuring ring (2) and a conical measuring body (3) with a compression spring (1). If a medium flow through the measuring ring (2) with sufficient flow velocity, the measuring body position shifts until a state of equilibrium is reached between the applied flow force and the measuring body plus spring force. The position of the measuring body (3) in the measuring ring (2) serves as a measure of the flow rate and is converted into a rotary movement by the permanent magnet encapsulated in the measuring body (3) via...

Heinrichs Messtechnik GmbH Design / Variation Aluminum indicator Optimized aluminium display Large and well-arranged scale 90° angle for best reading. Rounded edges and rims ensure a smooth draining of liquids after wet contact. A special anodization and paint finish make the indicator housing also suitable for outdoor use. Process connections: flange, thread, clamp, weld ends Stainless steel indicator Stainless steel indicator Large and well-arranged scale with 90° angle for optimal reading. IP65, IP66, IP67 protection for extreme applications. The round design ensures a smooth draining of liquids...

Heinrichs Messtechnik GmbH Linings / special materials PTFE lining for highest resistance This linning allows the use in special environments or for highly corrosive processes such as acids and lyes. Temperature max. 125°C Max. pressure resistance 16 bar High-pressure version Due to the unique design of the measuring fitting with cylindrical measuring tube and conical float, the devices can be manufactured with thick-walled measuring tubes without any problems. This allows the use in highpressure applications for which there are otherwise hardly usable measuring devices. e.g. high-pressure cooling...
