PURPOSE:To measure easily the quantity of a fluid jetted from a jet intermittently, by measuring pressure variation in a passage from a liquid source to the jet. CONSTITUTION:A glue 2 is sent out from a glue tank 1 by a compressed air 3. An interval from a pipe 4 in the tank 1 to a glue gun 5 is connected with hoses 9, 10 by using joints 6-8. The joints 6-8 are provided with pressure converter 14 and the output of the converter 14 is given to an electromagnetic oscillograph 16 and a memory scope 17 through an amplifier 15. The quantity of jetted fluid from the gun 5 is proportioned to the product of pressure drop and jetting time or the product of a rate of the pressure drop and the jetting time at each joint 6-8. |
