Abstract

Trykkmåleanordning og fremgangsmåte for å måle trykk l et undersjøisk rørformet element. Anordningen Innbe- fatter en stasjonær enhet (15) montert på utsiden av det rørformede elementet og en bevegelig enhet som vil bil nedsenket l en posisjon tllllggende den stasjonære enheten når trykket skal overvåkes. Den stasjonære enheten (15) har en deformasjonsmåler som vil overvåke trykket ved å måle deformasjon i det rørformede elementet. Den stasjonære enheten (15) har en lyssender som vil sende ut pulser som korresponderer med målt trykk. Den stasjonære enheten har en fotocelle som vil motta en lysstråle fra den bevegelige enheten. Lysstrålen og fotocellen tilveiebringer energi for den stasjonære enheten (15). Den bevegelige enheten har en mottager som vil motta enhver lyspuls fra lyssenderen og bringe den i forhold til en trykkmåling.Pressure measuring device and method for measuring pressure in a subsea tubular element. The device includes a stationary unit (15) mounted on the outside of the tubular member and a movable unit which will be immersed in a position adjacent to the stationary unit when the pressure is to be monitored. The stationary unit (15) has a deformation meter which will monitor the pressure by measuring deformation in the tubular element. The stationary unit (15) has a light emitter that will emit pulses that correspond to measured pressure. The stationary unit has a photocell that will receive a light beam from the moving unit. The light beam and the photocell provide energy for the stationary unit (15). The movable unit has a receiver that will receive any light pulse from the light transmitter and bring it relative to a pressure measurement.
