3.1 Likhoerekhoere tsa Lapeng
Likhoerekhoere tsa lapeng li na le motsoako oa lintho tse phelang, lintho tse tiileng tse leketlileng le likokoana-hloko. Likaroloana tse kang mantle, litšila tsa lijo le pampiri ea ntloana li leketliloe ka har'a mokelikeli.Methapo ea phallo ea ultrasound ea Dopplerli loketse hantle ho lekanya phallo ea likhoerekhoere tsa malapeng. Lintho tse tiileng tse emisitsoeng ka har'a likhoerekhoere tsa malapeng li fana ka libaka tse bonts'ang maqhubu a ultrasonic a lekaneng. Mohlala, lits'ebetsong tsa likhoerekhoere tsa masepala moo likhoerekhoere tsa malapeng tse tsoang malapeng a mangata li kopanang, li-flowmeter tsena li ka lekanya sekhahla sa phallo ka nepo, li nolofalletsa tsamaiso e sebetsang ea lifeme tsa kalafo ea metsi a litšila.
3.2 Metsi a Litšila a Liindasteri a nang le Metsi a Tiileng a Leketlileng
Liindasteri tse ngata li hlahisa metsi a litšila a nang le lintho tse tiileng tse leketlileng. Mohlala, indasteri ea merafo e hlahisa metsi a litšila a nang le likaroloana tse ntle tsa liminerale, 'me indasteri e etsang pampiri e ntša litšila ka likhoele tse leketlileng. Li-flowmeter tsa ultrasound tsa Doppler li ka lekanya phallo ea metsi a litšila a joalo a indasteri. Likaroloana tse tiileng metsing ana a litšila li bonahatsa maqhubu a ultrasound, e leng se lumellangsesupa-tsela sa phalloho bala lebelo la phallo. Indastering ea merafo, tekanyo e nepahetseng ea phallo ea metsi a litšila e bohlokoa bakeng sa tsamaiso e nepahetseng ea mehloli ea metsi le tšireletso ea tikoloho.
3.3 Likhoerekhoere tse nang le Lipululana tsa Khase
Mefuta e meng ea likhoerekhoere, haholo-holo lits'ebetsong tsa kalafo ea anaerobic, e na le lipululana tsa khase. Mohlala, litankeng tsa tšilo ea seretse sa limela tsa kalafo ea metsi a litšila, ho hlahisoa lipululana tsa methane le carbon dioxide. Li-flowmeter tsa Doppler ultrasonic li ka boela tsa lekanya phallo ea likhoerekhoere ka lipululana tsa khase. Lipululana tsa khase li sebetsa e le lipontšo tsa maqhubu a ultrasound, li nolofalletsa ho lekanya lebelo la phallo. Sena se bohlokoa bakeng sa ho beha leihlo ts'ebetso ea lits'ebetso tsa kalafo ea anaerobic le ho netefatsa ts'ebetso e sebetsang ea lifeme tsa kalafo ea metsi a litšila.

Difeme tsa ho sebetsana le dijo di hlahisa ditshila tse nang le mefuta e fapaneng ya dintho tse nyenyane, tse kang dikotwana tsa ditholwana, meroho le nama. Dikaroloana tse leketlileng ditshileng tsena di ka lemohuwa ke di-flowmeter tsa ultrasonic tsa Doppler. Ho lekanya phallo ya ditshila tse jwalo ho thusa difeme tsa ho sebetsana le dijo ho latela melao ya tikoloho le ho ntlafatsa mekgwa ya tsona ya kalafo ya metsi a ditshila.
