Impending bypass indicator

A fluid filter system, comprising:

• a fluid line for conveying a fluid under pressure to a fluid filter;
• an impending bypass indicator (IBI), comprising:
• a housing having a fluid inlet for admitting a fluid into an interior of the housing;
• a piston displaceable in the interior of the housing in response to a pressure variation of the fluid in the interior, the piston displaceable between a first position and a second position spaced apart from the first position, a piston magnet coupled to the piston;
• an indicator indicating an impending bypass of the fluid filter in response to the piston being in the second position;
• a housing magnet in the housing, the housing magnet engaging the piston magnet in the second position of the piston, the housing magnet generating a magnetic force acting on the piston magnet;
• a biasing element biasing the piston towards the first position with a biasing force inferior to the magnetic force;
• and
• an electromagnetic coil disposed adjacent the housing magnet, the electromagnetic coil selectively electrifiable to generate a second magnetic force opposite to the magnetic force imparted by the housing magnet to allow the biasing element to bias the piston towards the first position.
