A flow sensor apparatus that utilizes a pressure sensor with media isolated electrical connections. A cap can be attached to topside of the pressure sensor over a diaphragm to protect bond pads and wire bonds from a fluid media. A flow channel can be etched on the cap with an opening and exit on the sides of the cap so that liquid can flow through the flow channel. An inlet port and an outlet port can be attached to the channel's opening and exit to allow for fluid flow over the diaphragm. The flow channel creates a larger pressure over portions of the diaphragm that increases the deflection of the diaphragm, which increases an output signal of the pressure sensor. V-grooves can be created on two sides of the pressure sensor and in the cap to create the channel for the fluid in and out of the cap's cavity.
