M2M Question

07/29/2010 9:04 AM

My idea this time has to do with putting an ultrasonic flow meter in a remote area of a pipeline or flare. The flow meter has a MODBUS RTU option and can be powered with a PV and battery supply. I thought I had a working weapon with these guys but the MODBUS output of the flow meter contains analog and cumulative 4 byte, 32 bit integer and IEEE words that aren't supported by their equipment. I need to get that data out without grid power or short range data radios. Cell tower access is available and I'm convinced the technology is out there "somewhere". Any Ideas?

Hey Sir

During my practical year I were a student at SSE Cape and we have a RTU that you can link the flow meter up to and set the RTU to communicate Modbus RTU then on the other side you have any option that you haert want! You can go sms or gprs or digital radio or Wireless or Analogue radio. name the communication meduim and we can do it. What type of flow meter is it?

You can check there website out. Its www.sse.co.za! If they dont want to help you you can contact me a again!

Hope it help!

Check out Phoenix Contact's GSM/GPRS cell modem with a RS-232 port.

http://www.phoenixcontact.com/signal-level-matching/31261_40428.htm

It's a modem, as evidenced by DCD & DTR LED's; V.34, V.32.compatibilities and an appendix of AT commands.

If you're the integrator, I hope you're up on your AT commands; there's 20 pages of AT commands in the manual.
