Abstract:
A flow meter for use within a fluid system for measuring fluid flow in a flow path, the flow meter comprising:a) an elongate elastic stalk having a long axis, a first end, a second end, and at least a portion that is substantially oblong in cross section, with the longer sides transverse to the flow path;b) a target member having a substantially flat face attached to the first end of the stalk, and arranged to be positioned in the path of the fluid flow to be measured with the flat face of the target member transverse to the flow;c) a support element attached to the second end of the stalk for holding the target member in position;d) sealing means for sealing the support element into the fluid system;e) a plurality of strain gauges affixed to said longer sides of the stalk intermediate the first and second ends;f) a plurality of wires connected at one end to the strain gauges and passing sealingly through the support element to an area outside the fluid system; andg) a resilient coating on the strain gauges and wires to isolate them from the fluid.
