There are two types of sensors that deal with FLOW, a flow switch which is usually located just after the outlet of the heater or a pressure switch which is usually on the heater housing itself.

I have seen the pressure switch on the heater housing but that is inside the control box under the circuit board.

The pressure switch will look something like this:

The flow switch is like this:

Most likely you have a pressure switch.
