4-20mA Output Setup
The 4-20mA output of the sensor is scaled as:
• 4 mA = (Tank is Empty) = (Level is 0)
• 20 mA = (Tank is Full) = (Level is maximum height or volume)
The 4-20mA analog signal can be converted to one of three values (Level, Volume Remaining, or Volume
Consumed) in the controller receiving the output according to the above scale. For example, a nominal
100-gallon vertical tank, the maximum height is 36 inches. The tank volume is 100 gallons when it is filled
up to the maximum height 36 inches. The controller should be set up to convert 20 mA to 100 gallons, at
which the tank is full and the tank level is 36 inches.

NOTE
*
The nominal capacity provided by the tank manufacturer may be greater than the
maximum safe (net or effective) capacity that can be practically filled. Please keep this in
mind as you configure your LSP Series sensor for practical purposes.

Communication Using Modbus RTU
The LSP Series sensor can be configured as a Modbus slave device via RS-485. In addition to the level and
volume, many operational parameters, including warning and error messages, are available via a Modbus
RTU connection. Contact Pyxis Lab Customer Service (
) for more information.
