1. A nozzle to dispense a fluid, which comprises:
- a handle element;
a modular housing within said handle element, said modular housing being slidably removable from said handle element, said modular housing including;
a fluid flow passage extending therethrough, anda controllable flow control valve arranged in said fluid flow passage for control of fluid therethrough;
a flow meter arranged to measure a flow of fluid through said fluid flow passage;
an electronic data processing unit mounted in said handle element;
said electronic data processing unit including a data input port coupled to said flow meter for input of data indicative of fluid flow through said nozzle, wherein when said modular housing is slidably removed from said handle element, each of said flow control valve, said fluid flow meter, and said fluid flow passage remain with said modular housing and said electronic data processing unit remains with said handle element.

Abstract
An improved apparatus for dispensing fuel and the like is disclosed including a display unit and a data processing system. Flow of fuel is montitored and the information relating to amount, price, etc., may be displayed on a display unit mounted directly on the nozzle. The moving mechanical parts such as the valve are readily separable from the outer handle of the nozzle so that if a customer inadvertently drives a vehicle away with the nozzle still inserted in the gasoline tank, the costly mechanical components of the valve are retained at the gasoline service station.
