Abstract: Inventia se fata se refera la o sonda capacitiva de nivel, cu o carcasa de racordare si cu un electrod care iese în afara carcasei de racordare cu partea sa de palpare, aceasta parte de palpare fiind acoperita cu un învelis izolant. Inventia se refera la sonda capacitiva de nivel, cu un electrod care este acoperit pe partea sa de palpator cu un învelis izolant. Spatiul interior al învelisului izolant cominica cu atmosfera printr-un canal de evacuare. Di recipientul de masurare, ca urmare a permeabilitatii la abur a învelisului izolant, moleculele de apa care difuzeaza în spatiul interior al învelisului izolant por iesi astfel spre extrior, în atmosfera. La o reducere brusca a presiunii în recipientul de masurare, se evita atunci o crestere a presiunii în învelisul izolant si prin aceasta se evita o plesnire a acestuia.

Abstract: Crustacea, and especially shrimps are farmed in ponds, which can become contaminated with pathogenic bacteria, and in which predatory fish can consume a significant proportion of the shrimps if not controlled. The ponds desirably should contain a controlled level of phytoplankton. Such ponds can be treated with dilute peracid such as peracetic acid at a concentration that is significantly below the concentration which is lethal to the shrimps in order to control phytoplankton and/or pathogenic bacteria and to kill the fish. The peracid is preferably selected in the range of from about 0.5 to about 5 mg/l peracetic acid.
