| contd :- -4- The R.R. KS. gauge has the following advantages over other dashboard petrol gauges on the market. (1) It gives a correct reading of the quantity of petrol in the tank when the car is in motion. (2) It has no moving parts to wear. (3) It has no delicate bourdon pressure elements to be over- stressed or give rise to inaccuracy. (4) It cannot be damaged or put out of adjustment by positive pressure being built up in the tank when filling with the car on a camber.
