The OMNI-FIN calorimetric sensor measures small fluid flows, and has been designed especially for use in the foodstuffs industry.
The integrated transducer has a backlit graphics LCD display which is very easy to read both in the dark and in bright sunlight. The graphics display shows measured values and and units. The electronics have an analog output (4..20 mA or 0..10 V) and two switching outputs, which can be used as limit switches for monitoring minimal or maximal, or as two-point controllers. The switching outputs are designed as push-pull drivers, and can therefore be used both as PNP and NPN outputs.Over limit values are signalled by a red LED which is visible at a distance, and by a cleartext in the display. The stainless steel case has a hardened non-scratch mineral glass pane. Set up is adjustable by the programming bezel fitted with a magnet. It is not necessary to open housing to change the set up so ensuring the leakproof integrity of the unit.
Parameters are modified by turning the bezel (e.g. switching point, hysteresis...). To protect from unintended reprogramming, the bezel can be removed - thus acting as a key.

Counter C (hardware and software option):
Preset Counter with external reset option, complementary switching
outputs and actual value display
(modified wiring diagram!)
Counter C1 (software option):
Instantaneous value display with analogue output, pulse-volume
output and totalizer.
