ʻO ka mōʻaukala hoʻomohala ʻana o ka mika kahe o ka wahi-wikiwiki mai Lanry

ʻO kā mākou ʻāpana velocity flow meter kahi ʻano o nā mea kani ma ke kahawai hāmama a piha i ka paipu.Hiki ke helu i ke kahe, ka nui o ke kahe a me ke ana pae no na ano wai a pau (mai ka lepo lepo a hiki i ka wai lepo loa) ma o ka ultrasonic probe a me ke kaomi.Hoʻokomo ʻia ka probe i loko o ka paipu a ma lalo o ke kahawai hāmama.

Hana maikaʻi ʻia ka mīkini kahe wai holo wikiwiki ma nā ala hāmama no ka mālama ʻana i ka wai ʻino, ka mea ʻike kahe wai, nā mea kanu mālama wai ʻona a me ka hoʻoulu ʻana i ka mahiʻai, ka nānā ʻana i ke kaiapuni, ka nānā ʻana i ka wai kahe a me ka ʻino, ka wai lepo, etc.

No ke kahawai hāmama a ʻaʻole piha ka pipe doppler flow meter, aia ma lalo o nā pono:

1. ʻAʻole pono ia i kekahi flume a i ʻole weir a maʻalahi e hoʻouka;

2. 4.5 'īniha kala LCD hōʻike a me ka Ip68 papa pale, hiki ke hōʻike maikaʻi i kēlā kahe kahe, velocity, totalizer, pae a me nā ʻike waiwai ʻē aʻe e ka hōʻike LCD;

3. Ka waiwai ana maikaʻi o ka pae wai, conductivity, kahe a me ka holo ana;

4. Ikepili logger hana ultrasonic kahe ana mika no ka ikepili ka nānā 'ana a me ka hoike;

5.

Ka evolve o wahi velocity ultrasonic flow mika e like me lalo:

I ka makahiki 1996, ua hoʻokuʻu mākou i ka mua o ka QSD6526 doppler flow sensor.

Hiki i ka Doppler ultrasonic flowmeter ke ana i ka velocity kahe o ka wai a me ka pae wai ma o ka mīkini kaomi.

Mea hoʻoheheʻe doppler velocity me nā hale i hoʻopili ʻia

1. ʻO ke kahe o ka wikiwiki mai 21mm / s a ​​hiki i 4500mm / s

2. Mai ka 0 a hiki i ka 2m a me ka 0 a i ka 5m ke ana pae.

3. ʻO 2% ka pololei

I ka makahiki 2014, ua hoʻokuʻu mākou i ka mika lua-hanau: QSD6527 doppler flow sensor.

ʻO ka hana hou o ka holo ʻana o ka ultrasound flowmeter e like me kēia:

1. Ana 'ia ka pae wai e ka mea kani ultrasonic, ma mua o ke kaomi 'ana;

2. Hoʻohana ia i ka hoʻolālā kino i hoʻopaʻa ʻia epoxy a hiki ke loaʻa i ke ana kahe wai bidirection;

I ka makahiki 2018, ua hoʻolaha mākou i ka mana hou loa o ka velocity doppler flow monitor: QSD6537 doppler flow sensor.

1. Hoʻohui i ka hana o ke ana conductivity;

2. Hiki ke ana ʻia ke ana pae i loko o ka wai e nā ʻano ʻelua: ʻike ultrasonic a me ke kaomi kaomi;

3. Hoʻohui i ka hana o ke kaomi barometric a me ka uku wela;

4. Hoʻolaha kēia mika i ka ʻenehana DSP doppler digital, ma kahi o ka ʻenehana doppler simulation.ʻO ±1% ka pololei;

5. ʻO ka laulā holo o kēia mika mai ka 20mm / s a ​​hiki i ka 12 m / s;

6. ʻO ka pae kiʻekiʻe he 20mm a hiki i ka 5m ma ke kani ultrasonic a me ka 0mm a hiki i ka 10mm ma ke kaomi kaomi;

7. Hiki i kēia mika hou ke ana i nā wai maʻemaʻe;

8. Hoʻohui ka probe i ka hoʻopuka Modbus RTU;
