Om flowmåling med differenstryk

Gennemprøvet i en bred vifte af applikationer i forskellige brancher:
Differenstryktransmittere giver mulighed for kontinuerlig flowmåling sammen med differenstryktransmittere i gasser, dampe og væsker. Disse transmittere egner sig til alle former for medier, både i standardapplikationer og applikationer med høje procestryk og -temperaturer.

Måleprincip

Flowmåling anvendes til at bestemme den mængde, som strømmer igennem et rørsystem pr. tidsenhed. Flowmålingen ved hjælp af differenstryk udføres ved hjælp af differenstryktransducere. Differenstryktransducere omfatter åbninger, pitotrør eller venturirør. Når de er installeret i røret, genererer de et differenstryk, som måles ved hjælp af differenstryktransmitteren. Flowhastigheden beregnes i differenstryktransmitteren fra denne måleværdi.
