Measure Liquid Flow

[Aveiro]

Hello,

I´m working in a project and i´ve to measure temperature,liquid flow and pressure of water in pipes, but i don´t know how to do it using labview. Can anyone help me with some example codes.

Thanks.

LabVIEW is only the software which acquires and processes your measurements. You also need hardware, the equipment which converts the physiacl parameters like temperature, pressure, or fow to numbers the software can use. Have you selected the hardware? If so, what kind of data acquisition devices are you using?

What are you going to do with the data? Display it to a user, save it to a file, use it to control the process? ALl those things need to be decided before it makes sense to talk about code.

Hey you will need several things to get this to work.  First is a transducer that converts physical things into electrical impulses.  There are a number of them out there.  You next need to determine if the transducer puts out digital or electrical signals.  You also need to know the response time of the transducer so that you can buy a DAQ card with the appropriate sampling rates.  Then you need to load Labview and DAQmx.  Then start looking at examples on how to capture the data.  Good luck!

Oops, meant to put digital or analog signals.  Sorry.

Olá,

Acho que pelo nome posso escrever em portugues 🙂

Já tens os trsnsdutores e condicionamento?

Se sim, só tens de escolher uma placa baseado no sample rate, bus, resolução e nº de canais. A partir dai facilmente se arranjam exemplos instalados com o labview e na net.

Bom fim de semana

Hello Lynn,

I´ve already all the transducers ( pressure, flow and temperature). All of them puts out electrical signs.I´ve too a DAQ card (NI- USB-6008). The objective of my project is to get data and save it to a file, to later compare it with some theoric results.

Olá Carmo,

Já tenho os transdutores todos e a placa de aquisição de dados (NI USB-6008). O maior problema é mesmo fazer os programas em Labview.

Cumprimentos,
