The present invention relates to a connection arrangement for mechanically and fluidly connection a fuel filter to a fluid meter in a fuel dispenser and a method for assembly the connection arrangement. A pre-wired ground extends from a first end physically and electrically connected to a ground terminal on the electrical device. Fresh data is received via the full-time public network and recorded on a real-time basis in the database server. Furthermore, the wind velocity can be measured directly from Doppler shifts of the laser light, so the measurement can be accomplished at large standoff and at wide fields-of-view. Further improvements include a textured delivery chute and a method for dispensing a partially depleted roll of towel together with a fresh roll. The actuator includes magnetic field sources arranged on both sides of the magnetic field sensor, the magnetic field sensor and the magnetic field sources being arranged so that magnetic field lines generated by the magnetic field sources pass through the magnetic field sensor.
