Title
(EN) FLUID FLOW INDICATOR
(FR) INDICATEUR DE DEBIT
Abstract
(EN)
A fluid flow indicator is presented particularly for use within an existing gasoline pumping apparatus. The fluid flow indicator includes an outer cage member, a first hollow transparent cylindrical member contained within the outer cage member, and a second hollow transparent cylindrical member concentrically retained within the first hollow transparent cylindrical member. The fluid flow indicator may also include a filter member and fluid movement detection means contained within the second hollow transparent cylindrical member. The fluid flow indicator is especially designed to be retrofitted within any existing fluid flow line.
(FR)
Indicateur de débit destiné notamment à se placer dans une pompe à essence existante et comprenant une cage extérieure, un premier cylindre creux transparent placé dans la cage extérieure et un deuxième cylindre creux transparent maintenu concentriquement dans le premier cylindre. Ledit indicateur de débit, qui peut également comporter un filtre et un moyen de détection de mouvements du fluide placé dans le deuxième cylindre creux transparent, est conçu notamment pour un rattrapage de toute conduite existante où circule un fluide.
