Disclosed is a non-contacting liquid measurement system (60) preferably adapted to provide an averaged measurement in suitable units of measure of liquid (2), such as fuel, in a pressurized or unpressurized tank (4), such as a vehicular fuel tank, having an irregular shape such as irregular shaped bottom (6). The irregularity of bottom (6) results in variations in depth of liquid (2) across tank (4) that are accounted for by disposing a plurality of conduits (10, 12 14) in an array across tank (4) predetermined to provide the accuracy of measurement desired. Conduits (10, 12, 14) have respective ends (16, 18, 20) immersed in liquid (2) as close to bottom (6) as practical and are operable to provide respective liquid pressure signals (P1, P2 and P2) which are collected and averaged in a conduit (22) which delivers the averaged liquid pressure signal for exposure to flexible diaphragm (24) of an electro-magnetic transducer to which is secured a metallic armature having a base portion (25) and a projection (26) that is moved by diaphragm (24) in opposite directions within an electromagnetic field produced by a current carrying conductor (28) coiled about a core (27) and powered by suitable electrical power source (P). Circuitry (30) detects movement of the armature within the electromagnetic field and provides an electrical output signal (32) to an indicator (34) to provide a visual indication of the averaged measurement.
