Abstract
Methods and systems provide for detecting tampering of a fuel dispenser. Power is applied to a valve coil of a fuel dispenser. The valve coil is part of a control valve configured to accomplish a gradated fuel flow of the fuel dispenser. Current flowing through the valve coil is measured in response to the power being applied to the valve coil. The current measurements are compared with predetermined criteria and tampering with the valve coil is determined if the current measurements are sufficiently different than expected.
