- ʻO ke ʻano hoʻohālikelike: ʻano kaomi ʻino.
- Laulā kahe: (0.5～7800)m³/h (me ka mea i hoʻopaʻa ʻia no ka hoʻonui ʻana i 16000m³/h).
- Ua hoʻonui ʻia ka maopopo ʻole o ka hāmeʻa:U = 0.33% (k = 2). Hāʻawi i ka palapala hōʻoia i hāʻawi ʻia e ka ʻoihana hōʻoia metrology legal national.
- Ka pae pololei nozzle Sonic: 0.2. Hāʻawi i ka palapala hōʻoia i hoʻopuka ʻia e ka ʻoihana hōʻoia metrology statutory national, a ʻo ka mea hana ʻo 304 stainless steel.
- Paʻa kahe o ka hāmeʻa: ≤0.1%.
- ʻO ka moku Stagnation: Hoʻomalu ʻia ka mana o ka puʻe a me ka hoʻololi ʻana o ka mahana ma ka ʻikepili calibration i loko o 1/5 o ka maopopo ʻole o ke ana ʻana o ka hāmeʻa holoʻokoʻa.
- Ka mana kiko kahe hōʻoia: <3min. ʻOi aku ka maikaʻi o ka hoʻonā ʻana o ka manawa ma mua o 0.001s, me kahi awa puka aniani a hiki ke hoʻokaʻawale ʻia, ua hoʻonui ʻia ka ʻike maopopo ʻole o ke ana ʻana o ka manawa.U = 3×10-6( k = 2) , a ua hāʻawi ʻia kahi palapala hōʻoia e kahi keʻena hōʻoia metrology statutory a ʻoi aku paha.
- Nānā kaliber: DN10, DN15, DN20, DN25, DN32, DN40, DN50, DN65, DN80, DN100, DN125, DN150, DN200, DN250, DN300, ka huina o 15 calibers.
- ʻO ka pipeline nānā kumu: Aia 7 mau paipu nānā me nā anawaena o DN50 (kūpono me DN40/32/25/15/10), DN80 (kūpono me 65), DN100, DN150 (kūpono me 125), DN200, DN250, a me DN300. ʻO ka upstream o kēlā me kēia paipu nānā ʻana he puʻupuʻu pneumatic, kahi e hoʻoneʻe ai i ka neʻe ʻana a me ka hoʻopaʻa ʻana o ka ʻāpana paipu pololei i luna. Hoʻokumu ʻia ka mānoanoa o ka pā o ka pipeline ma ke kūlana aupuni, i hana ʻia me 304 mau mea kila kila, i hoʻolako ʻia me kahi muffler, a me kahi papaʻaina nānā ʻokiʻoki.
- Meter inspection pipeline: ʻo nā kūlana hana he haʻahaʻa haʻahaʻa maikaʻi ʻole, ea; pae leakage: 6-level sealing, zero leakage; Hoʻohana ʻia nā kiwi pōpō pneumatic ma ke ʻano he pipeline on-off valves no DN150 a ma lalo, a hoʻohana ʻia nā kiwi pneumatic butterfly e like me ka pipeline on-off valves no DN200 a i luna.
- Nānā ʻia nā ʻano o nā mika kahe: mīkini kahe kahe, vortex flowmeter, swirl flowmeter, ultrasonic flowmeter, differential pressure flowmeter, positive displacement flowmeter, Coriolis mass flowmeter, thermal gas mass flowmeter.
- ʻO ka mea hoʻouna puʻe puʻupuʻu: ʻo 0.075 ka pae pololei, ka manawa pane: ≤1ms, ʻo ke ana ʻana (0～110)kPa. E hoʻonoho i 7 mika inspection pipelines e kaʻana like 1, 1 stagnation ipu nui e uniformly laʻana 3 helu, 1 stagnation pahu liʻiliʻi, he 3, a hāʻawi i nā palapala hōʻoia i hoʻopukaʻia e ka moku'āina a ma luna o statutory metrology hōʻoia 'oihana. E hoʻonohonoho i 1 pahu pahu pahu pahu nui a me 1 liʻiliʻi me ka pae pololei o 0.5.
- Mea hoʻouna wela: ʻO ka hapa nui i ʻae ʻia ʻo ± 0.2 ℃, ʻo ka helu puka ʻana he 0.1 ℃, a ʻo ke ana ʻana he (0～50) ℃. E hoʻonoho i hoʻokahi no kēlā me kēia mika inspection pipeline , ʻelua moku stagnation nui, a me hoʻokahi moku stagnation liʻiliʻi, he 10 ka nui, a hāʻawi i kahi palapala i hāʻawi ʻia e ke keʻena hōʻoia metrology statutory ma ka pae panalāʻau a i luna paha.
- Mea hoʻouna haʻahaʻa haʻahaʻa: ʻO ka hapa nui i ʻae ʻia ± 2%RH, ke ana ʻana ʻo (0～100)%RH. E hoʻonoho i 1 pahu stagnation nui a me 1 pahu stagnation liʻiliʻi, he 2, a hāʻawi i palapala hōʻoia i hāʻawi ʻia e ke keʻena hōʻoia metrology statutory ma ka pae panalāʻau a i luna paha.
- Hoʻopaʻa ʻia: Mālama ka mea hana i ke kaomi no 5 mau minuke, a ʻo ka nui o ka hoʻololi ʻana o ka lākiō o ke kaomi piha ʻana i ka wela piha i ka pahu stagnation ʻaʻole i ʻoi aku ma mua o 0.1%.
- Valve: Ke hoʻohana nei ke kūlana nozzle i ʻelua mau kiwi pōpō o luna a me lalo, hoʻohana ʻelua i nā kiwi pōpō pneumatic, pae leakage: 6 pae hoʻopaʻa, zero leakage.
- ʻAʻole ʻoi aku ka nui o ke kaomi hope koʻikoʻi ma mua o ka 0.8; i ka ≤ 64 m³ / h ka nui o ke kahe, ʻaʻole ʻoi aku ka nui o ke kaomi hope koʻikoʻi ma mua o 0.5.
- Hāʻawi mana lako polokalamu: AC 3×380V～50Hz; ʻAʻole emi ka mana hoʻolaha āpau ma mua o 250kW.
- Nā hōʻailona o ka mika ma lalo o ka hoʻāʻo: pulse (frequency) hōʻailona, hōʻailona analog (4-20) mA, mika heluhelu pololei me ka ʻole o ka transmitter (multimedia), etc.
- Mea lako: ʻO ke kino o ka mīkini a me ka ʻāpana ana i hana ʻia me 304 stainless steel, a ʻo nā lako lumi pahū a me nā kākoʻo pipeline i hana ʻia me ke kila kalapona i pena ʻia no ka pale ʻana i ka corrosion.
- ʻAno hoʻomalu: Koe wale no ka hoʻopaʻa lima ʻana i ka mea hana i hoʻāʻo ʻia, hiki ke hoʻopau ʻia nā calibration ʻē aʻe a pau ma ke kamepiula (e hoʻokomo wale i ka ʻike pili a me nā ʻāpana o ka mea hana i hoʻāʻo ʻia), a i ʻole i hoʻopau lima ʻia.
E kākau i kāu leka ma aneʻi a hoʻouna mai iā mākou
