Abstract

The novel embodiments include a method, system and device for measuring a fluid characteristic in a conduit. The novel method includes applying a planar force to the conduit and receiving a pressure from the conduit. The pressure is responsive to the fluid and the conduit, where the pressure is received within a predetermined area. Also, the novel method includes processing the pressure to determine the fluid characteristic. The novel device includes a support structure for supporting the conduit and a sensor head in cooperation with the support structure. The sensor head applies a planar force to the conduit, and has a portion least equal to an outer radius of the conduit. The device also includes a pressure transducer located on the sensor head. The pressure transducer receives a pressure from the conduit that is responsive to the fluid and the conduit.
