Signet Compak Flow Transmitter - 8512 - This has been replaced by 8550 - take me there

8512.jpg (12850 bytes) This is a two or three wire device that transmits an analog signal of 4 - 20 mA from input from any of Signet's Flow Sensors 

The unit uses a Loop Power of 17 to 30 VDC.  This will provide signal for a Signet or other processor controller.
