Abstract
A method for measuring pressure includes securing a flow channel to a chassis of a measurement device, the flow channel having a flexible wall with a first mechanical engagement feature presented from an external surface thereof. The method also includes engaging the mechanical engagement feature with a complementary engagement member connected to a force transducer, the securing being effective to immobilize the flow channel relative to the force transducer, and detecting at least one of the position and orientation of the of the flow channel relative to transducer and comparing to at least one of a predefined position and orientation. Further, the method includes generating a signal responsive to the detecting, flowing a fluid through the flow channel, and transmitting forces caused by displacement of the flexible wall through the complementary engagement member to the force transducer. Further, electrical signals are generated responsively to a state of the force transducer.
