Ka Meter Holo Wai Doppler Paʻa Lima i hoʻohana ʻia e ka pila no ka Sewer

Ua hoʻolālā ʻia nā mika kahe ultrasonic Doppler e ana i ke kahe volumetric o nā mea paʻa a i ʻole ka wai aerated i loko o ka conduit pani, pono ka laina paipu e piha i nā wai me kekahi mau pehu ea a i ʻole nā ​​​​mea paʻa i hoʻokuʻu ʻia. Hiki i kekahi ke hōʻike i ka nui o ke kahe a me ka totalizer kahe, a pēlā aku. Eia kekahi, ua hoʻonohonoho ʻia me 4-20mA, nā hopena OCT. He kūpono nā mika kahe lima no ka nui o ka paipu mai 40mm-4000mm. Hiki iā ia ke hana ma nā wahi he nui o ka mahana hana -20 a 60 ℃. Hoʻohana nui ʻia ia i nā paipu piha piha, e like me ka wai ʻino maka, ka sludge i hoʻāla ʻia, ka wai lepo, ka pulp, nā slurries pepa / kemika, ka hoʻokahe wai a me ka recirculation mining a pēlā aku.
