Calorimetric flow transmitter OMNI-F

for liquidsgascompact

●Flow indicator for industrial use, without moving parts ●Short response times for a calorimetric sensor ●Medium comes into contact with only one material ●Analog output 4..20 mA or 0..10 V ●Two programmable switches (push-pull) ●Graphical LCD display, backlit (transreflective), can be read in sunlight and in the dark ●Programmable parameters via rotatable, removable ring (programming protection) ●Full metal housing with non-scratch, chemically resistant glass ●Rotatable electronic head for best reading position ●Small, compact construction ●Simple installation Characteristics The calorimetric sensor measures the flow speed in aqueous fluids. The display shows the measured value in a range from 0..100 % as a digital value and as a bar graph. The measured value is output as a 0/4..20 mA value. Both the 0/4 mA and the 20 mA value can be programmed via a scaling of the display range, and so the sensor can be adapted to any flow speed lying within the overall range. Measurement is supported in terms of temperature compensation and signal processing (linearistion, interpolation, amplification) by the use of a microcontroller Because a conclusion on the whole cross-section is drawn based on a point measurement in a pipe, the accuracy achievable is not so good as with a flow sensor in a permanently installed tube (OMNI-FIN or FLEX-FIN). By turning the programming ring to right or left, it is simple to modify the parameters (e.g. switching point, hysteresis...). To protect from unintended programming, it can be removed, turned through 180 °, and replaced, or completely removed, thus acting as a key
