| 1. A modular backpressure sensor comprising:
a modular housing configured to removably engage a fluid delivery nozzle, the modular housing defining a pressure sensing
chamber configured to communicate with a fluid flow channel within the fluid delivery nozzle;
a pressure response member situated within the modular housing and configured to communicate with a flow shut-off valve within
the fluid delivery nozzle;
a biasing member situated within the modular housing and configured to react to pressure on the pressure response member;
and
a retainer configured to retain at least one of the biasing member and the pressure response member within the modular housing;
and
an interface of the modular housing configured to engage the fluid delivery nozzle and to communicate backpressure to the
modular housing, wherein the interface comprises attachment means configured to engage corresponding attachment means on the
fluid delivery nozzle and further comprises a pressure communication element configured to communicate backpressure within
the flow channel of the fluid delivery nozzle into the modular housing from within the flow channel of the fluid delivery
nozzle.
