ABSTRACT

This chapter discusses a turbine flowmeter consists of a turbine element, inside a housing, the angular velocity of which is essentially proportional to volume flow rate of liquid. The rotations of the turbine element are picked up by an electromagnetic pickup and a pulse rate or frequency is recorded. The chapter investigates the effect of kinematic viscosity and corrects for very effectively. It discusses rather briefly dimensional analysis as it has been applied to the operation of the turbine flowmeter. The chapter also investigates data from a calibration of a turbine flowmeter and the determination of the linear region of the flowmeter. The “linearization” process described by Jones delineates the region of linear performance of the turbine flowmeter and determines the parameters a and b in the linear equation. It becomes possible to systematically investigate the performance of the flowmeter in the linear region, the region of precise application of the flowmeter.
