Connecting the Analog Level Sensors

Any level sensor providing a 4-20 mA process loop signal can be used by the flowmeter.
After installing the external level sensor according to the manufacturer's instructions, use a twin-axial,
shielded cable to connect the input to the terminal strip.
On most systems the terminal strip for the level inputs is located on the extreme right hand end of the
connector panel shown in Figure 4-6.
Input impedance for each channel is 100 ohms.
For typical connection configurations see the following Figure 4-5.
