A Serious Problem of the Heated Thermocouple Flowmeter

Regional Blood Flow in Skeletal Muscle Measured by the Heated Thermocouple Method during Electrical Nerve Stimulation of the Canine Gracilis Muscle.

“…Measurement of blood flow using HTC methods can be unreliable, since there is some distance between the hot junction (the sensor probe for temperature) and the heater. The direction of blood flow change can therefore influence estimation of blood flow in the tissue (Satoh et al 1980). In an attempt to overcome this disadvantage, we set the hot junction in the center of the heated coil.…”
