Calibration of turbo-tachometric flowmeters

Conclusions

• 1. The proposed form of the calibration relationship is confirmed satisfactorily by experiments with flowmeters of two different constructions.

• 2. The existence of a self-simulating region with respect to π₂ in the receivers types R-I and R-II opens up possibilities for making turbo-tachometric flowmeters insensitive in the range of measured flows to variations of viscosity and, hence, to the temperature of the liquid.

• 3. The compiling of general or individual calibration curves for existing types of turbo-tachometric flowmeters will provide the possibility of introducing corrections to the instrument readings taking into consideration the viscosity and density of liquids.

• 4. Further extended research is necessary in order to standardize the receiving converters for turbo-tachometric flowmeters.
