I'm a very new user to Arduino attempting to begin my first project. I'd like to interface a small LCD screen with a Transonic flow sensor to display realtime readings of flow rate. I'm working with Transonic's PXL-Series clamp-on flow sensor (H5XL) leading to a Transonic HT110 bypass flowmeter which is then interfaced to ADInstruments' LabChart software via ADInstruments' PowerLab (16/35) hardware. Flow rate readings sampled from the Transonic flow sensor are already being displayed on a computer monitor with LabChart but I need to create an additional, external display screen showing that flow rate reading. This project is intended to allow an individual performing a procedure approximately 10 feet away from the monitor with a more convenient way to view the flow rate readings. I should mention that the Transonic flow sensor can reach a maximum output of 5V and must be interfaced with an arduino board that is capable of reflecting a sampling rate of 400/second. Additionally, the LCD screen display must be hardwired to receive input as several devices in the room have diminished the efficacy of RF transmission. I am currently in the stage of purchasing the materials I will need to begin work on the project and would greatly appreciate any advice on which arduino products would be most practical, suggestions for writing the code, and how to set up the circuitry to interface the arduino board with my LabChart software or PowerLab hardware. Thank you in advance for your guidance and suggestions!
Even if you have quite a bit of C/C++ programming experience, you still need to look through the simple examples that come with the Arduino IDE, in order to familiarize yourself with the special features of the Arduino, and possibly, programming a real time microcontroller.
Learn how to blink an LED without using the delay function, wire up and read a pushbutton or a voltage, communicate with another computer, etc.
the Transonic flow sensor can reach a maximum output of 5V and must be interfaced with an arduino board that is capable of reflecting a sampling rate of 400/second.
Any Arduino can read a voltage between 0 and 5V with 10 bits resolution, at sampling rates much higher than that.
Hint: for advice on how to interface an Arduino and device XYZ, google "arduino XYZ".

Sorry, but had to spread it out to point form.
Can you please tell us your electronics, programming, Arduino, hardware experience?

I apologize for the delayed response. To respond to questions about my level of experience; thus far, I have worked my way through a majority of the example tutorials for LEDs as well as basic sketches for PWM usage. For the purposes of this project I've decided on the use of a ST7565 positive GLCD and have been working through the example sketches in that library to begin to make sense of it in comparison to the liquid crystal library. I have intermediate level experience using matlab for various projects such as creating GUIs, extracting/manipulating data, and photo editing/statistical analysis. Other than the limited electronic experience picked up while finishing a biomedical engineering master's degree, I've mostly taught myself about circuitry through online tools and books like "Arduino for Dummies".
Attached is a picture of my powerlab setup (red box is where the transonic flow sensor would be connected, the generated analog signal feeds into the powerlab which generates digital signal to feed into Labchart software, at this time input 7 is the flow sensor), an image of the front/back connections available on the powerlab hardware, as well as some information regarding the two analog outputs on the powerlab.
At this time I am trying to figure out how I can duplicate the flow reading being displayed on my Labchart software onto my GLCD.
Hi Spinaa
Have you find out a solution to connect and sync Powerlab hardware with Arduino?
