Abstract
We present a computational system, based on a PC and LabVIEW, to test and
characterize the response of conical cup type mechanical flow meters with
vertical axes. A mechanical flow meter is a device used mainly to measure and
calculate the velocity of water flow in rivers and open channels.
These devices suffer mechanical imperfections over time, which is why it is
important to calibrate them, normally twice a year, depending on the length of
time the device has been used for. At the Mexican Institute of Water Technology
(IMTA in Spanish) a circular water tank was designed and developed for the
purpose of testing these meters.
This paper shows the automation systems designed to control the tests to
calibrate these mechanical meters. The system is based on LabVIEW. LabVIEW
is a general purpose programming tool with extensive libraries for data
acquisition instrument control, data analysis, and data presentation. With this
tool and a special hardware interface, it was possible to automate the process to
test these mechanical meters.
The system is called SCM (System for characterization of mechanical
meters). SCM controls the testing of two mechanical meters simultaneously, and
has some user control features that provide the Operator with an easy to use
human machine interface.
Keywords: mechanical flow meters, testing laboratory, LabVIEW based
automation system.
