Product Overview
Engineered for hygienic processing lines, the Baumer FlexFlow PF20H (article number 11199380) combines calorimetric flow and media temperature measurement into a single wetted insertion probe. It operates on a thermal dispersion principle without moving parts, monitoring liquid velocities up to 400 cm/s alongside process temperatures up to 150 °C. Built with AISI 316L stainless steel wetted surfaces and an integrated 50.5 mm sanitary clamp connection, it delivers an analog 4-20 mA signal over a standard M12 4-pin interface.

Frequently Asked Questions
What process connection does this sensor use?
It features an integrated 50.5 mm diameter sanitary clamp flange (Baumer connection identifier C04), compatible with standard 1-1/2 inch Tri-Clamp, ISO 2852 DN 33.7/38, and DIN 32676-A DN 25/32/40 hygienic ferrules.
What is the immersion depth of the probe?
The insertion stem measures 75 mm from the hygienic clamp sealing face to the probe tip.
How does article number 11199380 match this model configuration?
Baumer article number 11199380 designates this exact configuration: model PF20H-11.010.C042.20.0.0000.0 with a 75 mm immersion probe, 50.5 mm hygienic clamp connection, 12 to 32 VDC supply, and 4 to 20 mA analog output.
No impellers to foul and no seals to weep, just solid 316L stainless steel reading the heat of the stream. Clamp it into the ferrule, wire the loop, and let the process run.
