MEASUREMENT PECULIARITIES OF OIL PRODUCTS QUANTITY IN AUTOMOBILE TANKS
In oil products loading and unloading express record of filling-up of moto transport tanks is of special value particularly at night. Hardware has been developed with relative acoustic measurements of oil products mass with consideration for “free” air volume by sound pressure measurement with compensation for influence of variable external and internal technological conditions. The relative level of sound pressure is controlled at various oil products volumes.
Keywords: sound pressure, condenser microphone, oil product volume, sound pressure alignment channel
