A device and method for monitoring a fluid characteristic, such as flowrate, of a fluid within a fluid circuit having a preexisting filter head. The device is installed on the filter head in place of the existing filter element. The apparatus includes a housing having an internal surface defining an interior volume, a coupling for connecting the housing to the filter head and a flow indicator or other fluid responsive device actuated by flow of the fluid through the device. The fluid characteristic is monitored by observation of the fluid responsive component.
