MOBILE CALIBRATING APPARATUS FOR CONTROL OF VOLUME METERS FOR LIQUID, ESPECIALLY PROPELLANT PUMPS IN THE TRAFFIC SECTOR

摘要

the invention relates to an apparatus for adjusting the calibration of gas pumps, particularly in the transport sector. the apparatus is placed on a vehicle, more specifically on a trailer.the apparatus has at least one rod (10) is used to measure a given quantity of gas, the gauge is placed in a suspension shaft (49 - 52), which is elastically soft (48) and that can be locked in the course of the operation, during transport, by means of. your support (53 - 59).a gauge (10) is divided into a lower compartment (11) and a measure of upper (14) which is connected to a foam compartment (11) by a measurement with a glass bottle (12) (13) for measuring and reference for the reader (22).the upper foam (14) is split (35 to 37) to a holding tank (5) placed at the bottom of the apparatus (1) and the gauge (10) can be connected, via a discharge valve (20), a remote control reception tank (5) where the gas can be pumped and (e) stored in a reservoir to hold (64) located at the top of the apparatus (1).here, the gas is returned to the storage tank in the gas station by means of a tip (72) that, with the action of gravity or a pump.an electrical generator (78) which can be driven by a transmission belt (79 - 84) connected to one of the wheels of the vehicle (2), may be a rechargeable battery (87), and a pressure tank (88, 89) containing a gas under pressure, flammable, such as carbon dioxide,. rge of remote control of the discharge valve (20).a control device for controlling functions of the apparatus in time is then proposed.
