Abstract

This paper sets out to improve the operation of measuring capacity using flow meters which are used in rivers or irrigation channels to perform these measurements. The development is based on the change in taking readings to make the flow measurement using new technologies. This work is considered as an important factor in reducing time, especially when several measurements are required. With this measurement process proposed, there is to be a reduction of measurement time to extend the operating life of the flow meter. The project is working through an FM transmitter and receiver, which remotely send the information to provide the mechanical flow meters of conical cup type with vertical axis, to the receiver. This information is captured in the receiver, is filtered and passes a DAQ card. The information is processed on a PC through the Data Acquisition System, developed in Labview Keywords: mechanical flow meters, testing laboratory, RF (radio frequency) communication, LabVIEW based system.
