Abstract
Sposób weryfikacji odporności gazomierzy miechowych na pole magnetyczne magnesów neodymowych charakteryzuje się tym, że w pierwszym etapie przeprowadza się próbę szczelności oraz badanie metrologiczne gazomierza, podczas którego wyznacza się początkowe błędy wskazań E1 oraz początkową stratę ciśnienia ΔP1 w gazomierzu bez magnesu neodymowego, poprzez sześciokrotny pomiar w każdym strumieniu objętości: a następnie oblicza się średnia wartość z tych błędów Es1, oraz średnią wartość straty ciśnienia ΔPs1, po czym w drugim etapie przykłada się magnes neodymowy o parametrach co najmniej: typ N38 o gęstości energii 286 ÷ 302 kJ/m3 i wymiarach ø 70 x 30 mm do obudowy gazomierza w miejscu, w którym znajdują się ferromagnetyczne elementy organu pomiarowego lub układu rejestracji objętości gazu gazomierza.The method of verifying the resistance of bellows gas meters to the magnetic field of neodymium magnets is characterized by the fact that in the first stage a leakage test and metrological test of the gas meter are carried out, during which the initial errors of E1 indications and the initial pressure loss ΔP1 in the gas meter without a neodymium magnet are determined, by measuring six times in each volume stream: and then the average value of these errors Es1 is calculated, and the average value of the pressure loss ΔPs1, then in the second stage a neodymium magnet with the parameters of at least: N38 type with an energy density of 286 ÷ 302 kJ / m3 and dimensions ø is applied 70 x 30 mm to the gas meter housing in the place where ferromagnetic elements of the measuring device or the gas volume recording system of the gas meter are located.
