Gukurikirana urujya n'uruza: Guhura n'Ibibazo byo Gufungura-Umuyoboro wo gupima mu bikorwa bya Komini

Imwe mu miterere yihariye yo gupima ni imiyoboro ifunguye, aho urujya n'uruza rw'amazi ku busa rimwe na rimwe “rufungura” ikirere. Ibi birashobora kugorana kubipima, ariko kwitondera neza uburebure bwimigezi hamwe numwanya wa flume birashobora gufasha kuzamura ukuri no kugenzurwa.

Mwisi yo gupima amazi neza kandi neza, hariho ibikoresho byinshi byo guhitamo. Ukurikije uko ibintu bimeze, urujya n'uruza rw'amazi hamwe n'aho bisabwa gupima amazi, birashoboka cyane ko igisubizo cyiza cyo gupima amazi. Nyamara, kimwe mu bice byihariye byo gupima ni iy'imiyoboro ifunguye - ikubiyemo imiyoboro yo kuhira, imigezi, inzira z’amazi, hamwe n’imyanda y’amazi y’isuku n’amazi y’imvura - aho urujya n'uruza rw’amazi ku busa rimwe na rimwe “rufungura” ikirere.

Gupima neza umuyoboro ufunguye birashobora kwerekana ko bitoroshye. Imiyoboro ifunguye-itemba ntabwo ihatirwa, nuko rero ibipimo byuzuye bipima nka Venturi, electromagnetic cyangwa strap-on-transit-time flux ntabwo bishoboka. Inzira isanzwe yo gupima imigezi inyuze kumuyoboro ufunguye ni ugupima uburebure cyangwa “umutwe” w'amazi kuko anyuze kubuzwa (nka flume cyangwa weir) mumuyoboro. Ku muyoboro uwo ari wo wose ufunguye urimo ubusa-unyuze mu bikoresho byihariye bigenzurwa, uburebure bw’imigezi (umutwe) burashobora kuba ikimenyetso cyerekana ingano y’amazi bityo kikaba gitanga igipimo cyiza cyerekana umuvuduko.

Umwanzuro
Ibipimo nyabyo byo gupima imiyoboro ifunguye biragenda biba ngombwa. Ahantu hahanamye, gutembera cyangwa guhinduka gukabije kuri geometrie birashobora, kandi akenshi birashobora kugira ingaruka mbi mubyukuri no kwizerwa bya flume gakondo ya Parshall. Bitewe no kugabanya amazi yimigezi aboneka hamwe nakamaro ko gupima no gucunga neza amazi yimyanda hamwe nandi mazi atembera neza, hagomba kwitabwaho kugirango habeho igisubizo kiboneye. Kugirango utange ibisubizo byizewe, bikurikiranwa bisaba kureba ibirenze amaturo gakondo kubisekuruza bizaza byukuri bishobora kugenzurwa neza.
