A bidirectional flow sensor (800) for automated systems includes a heater (18) which is maintained at a constant temperature above the temperature of the fluid flowing past the heater. A pair of temperature sensors (26a,26b) is located to either side of the heater (18). The temperature sensors may b

A bidirectional flow sensor (800) for automated systems includes a heater (18) which is maintained at a constant temperature above the temperature of the fluid flowing past the heater. A pair of temperature sensors (26a,26b) is located to either side of the heater (18). The temperature sensors may be two-terminal constant-current devices, electrically connected in series, so that the current is controlled by the sensor sensing the lower temperature, which is on the upstream side of the heater. In one embodiment, a processor (1010) processes the signals produced by the temperature sensors to produce a flow-direction indicating signal. The bidirectional sensor is adapted for interfacing with a digital network.

The rheometer of claim 10 wherein the first surface and the second surface are plates and the at least one sample includes a plurality of samples and wherein the at least one shear stress sensor is adapted to provide a signal related to the shear stress of each of the plurality of samples. 12. The rheometer of claim 11, wherein the light is polarized light that is input into the stress-sensing material, and is guided through a polarizer means having a polarization direction different from that of the input light. 13. The rheometer of claim 12, wherein the input light is polarized by a single mode input fiber. 14. The rheometer of claim 13, wherein said stress-sensing material is a short portion of the single mode input fiber. 15. The rheometer of claim 14, wherein a single mode fiber comprises a light input portion, a middle portion as the stress-sensing material, and a light output portion. 16. The rheometer of claim 15, wherein a surface of the stress-sensing material, which may be brought into contact with a sample is provided with a reflective layer, and the polarized light is directed to the stress-sensing material by an oblique angle with respect to the reflective layer, whereby the polarizer means is positioned to receive light reflected by the reflective layer. 17. The rheometer of claim 12, wherein the polarizer means has a polarization direction that is perpendicular to that of the input light. 18. The rheometer of claim 9, wherein the light is polarized light that is input into the stress-sensing material, and is guided through a polarizer means having a polarization direction different from that of the input light. 19. The rheometer of claim 18, wherein the input light is polarized by a single mode input fiber. 20. The rheometer of claim 19, wherein said stress-sensing material is a
