Chii chinonzi BTU meter?

BTU Meter mudziyo unoshandiswa kuyera kushandiswa kwekupisa (simba), kunyanya pakutarisa kupisa kunopfuudzwa nemvura (yakadai semvura, mhinduro dze ethylene glycol, nezvimwewo) panguva yekuyerera. Inowanzo shandiswa mumamiriro ezvinhu akadai seHVAC (Heating, Ventilation, and Air Conditioning), manejimendi esimba remaindasitiri, uye masisitimu efiriji.

Basa Guru:

Nekuyera mwero wekuyerera kwemvura uye musiyano wekupisa pakati pekupinda nekunze, inoverenga kukosha kwekupisa ichishandisa mafomura ethermodynamic. Chiyuniti ichi chinowanzova British Thermal Unit (BTU) kana mayuniti ayo anobva (akadai seMBTU, mamiriyoni eBTU).
Fomura yekuverenga ndeiyi:
Q=Kuyerera Kwemvura×Kugona Kupisa Kwakananga kweMvura×(Kupisa Kunopinda Mukati−Kupisa Kwekubuda Mukati)
(apo kupisa, Q iri muBTU).

Kupatsanura uye Nheyo:

Nekuyera Nheyo:
Rudzi rweMichina: Inoita kuti mvura ifambe nepakati pezvinhu zvakaita semaimpellers uye inoverenga kupisa nekushandisa maprobes ekupisa (zvakafanana nemamita emvura echinyakare).
Rudzi rweUltrasonic: Kuyera kuyerera kwemvura uchishandisa nzira yeUltrasonic time-of-flight, zvichipa kunyatsorongeka kwakanyanya uye kusashanda zvakanaka (semuenzaniso, Inline ultrasonic heat meters).
Rudzi rweElectromagnetic: Inoyera kuyerera kwemvura zvichibva pakushandiswa kweelectromagnetic induction, yakakodzera kushandiswa kwemvura inofambisa mvura.

Nenzira Yekuisa:
Rudzi rwekuisa (Inline): Yakaiswa zvakananga mukati memapaipi, yakakodzera mamiriro eindasitiri.
Rudzi rweClamp-On: Yakabatanidzwa kudivi rekunze remapaipi pasina kuboorwa, zviri nyore kuisa asi nemazvo zvichikanganiswa nemamiriro emapaipi.

Maitiro Ekushandisa:
Kutarisira Simba rekuvaka: Kutarisa kushandiswa kwekupisa mumasisitimu emhepo inotonhodza, mabhoyila, kana masisitimu ekupisa kwepasi pevhu kuti uongorore kubhadharisa kana kushandisa simba zvakanaka.
Maitiro Emaindasitiri: Kuyera kupisa mumasisitimu ekutonhodza/kudziyisa mumaindasitiri akadai seinjiniya yemakemikari uye kugadzira chikafu.
Masisitimu eRefrigeration: Kutarisa mashandiro esimba rekuchengetedza zvinhu zvinotonhora uye mafiriji.

Zvakanakira:
Kuyera Kushandiswa Kwesimba: Kunobatsira vashandisi kunzwisisa mashandisirwo ekupisa uye kugadzirisa kugoverwa kwesimba.
Kunyatsoongorora: Mhando dzeUltrasonic dzinogona kuita zvikanganiso zvakaderera kusvika ± 0.5%, zvichizadzisa zvinodiwa pakugadzirisa kutengeserana.
Ungwaru: Hunotsigira kutapurirana kwedata kure, kuchengetwa kwezvinyorwa zvekare, uye kugadziriswa kuEnergy Management Systems (EMS).
