I'm a complete newby to the Raspberry Pi, although interested in electronics and IoT.
For a dedicated project, I'm looking for someone how can develop/build/test a complete board to read out temperature corrected fuel flowmeters. The data of the flow transmitter and the temperature transmitter, needs to be read in and send out over ethernet to a central industrial PC.
BASIC SYSTEM LAYOUT:
The basic system layout will be that we’re able to connect up to four individual flowmeters (with each one pulse transmitter & temperature sensors) to a hardware device and transfer the data by ethernet to a central PC where the data will be processed.
SPECIFICATION PULSE TRANSMITTER:
Type Omnipolar Hall Switch
Max. supply volts 24V (at 150°C)
Max. supply current 9 mA
Internal resistance 3,4 kOhm (1k2 serial, 2k2 pull-up)
Pulse output Active, pulse level depends on total circuit resistance*
Wire colour red (24 V sensor supply), black (gnd) , yellow (pulse)
The number of pulse depend on the size/type of the meter and do vary between 5 P/L up to 160 P/L
SPECIFICATION TEMPERATURE TRANSMITTER:
Temperature range as indicated on the instrument text plate
Wire colour Brown (PT100-1), Blue (PT100-2), White (PT100-sense)
The main question is, who can develop/build/test such a board based on the raspberry Pi?
