An apparatus for volume determination in a pump unit for fluid, such as fuel, in which a first and a second metering means are provided which are juxtaposed. The metering means each comprise a metering casing having a shaft assembly, which is adapted to be rotated when fluid flows through the metering casing. Each metering means further comprises a pulse generating means, which has a frequency generator and a pulse generator and which is adapted to convert the rotation of the shaft assembly into pulses. The frequency generator is connected to the shaft assembly for rotation therewith, mounted in the respective metering casings. The two pulse generators are adapted to sense, in a contactless manner, rotation of the respective frequency generators and to emit pulses in relation thereto. The two pulse generators are arranged in a separate pulse generator module and are encompassed in a pulse generator casing, which is detachably connected to the metering casing. The invention is also directed to a separate pulse generator module. |
