The external sensor is calibrated on 0 bar - 0.3 bar; so 4mA corresponds to 0 bar and 20mA corresponds to 0.3 bar.

The formule to use is :

Delta_Pressure  = (0.01875 * Measured_Value_mA - 0.075) * 100 000                    [Pascal]

Fluid_Level = Delta_Pressure / (9.81 * Fluid_Density)                                             [m] [Fluid_Density in kg/m3]

ex: Measured_Value_mA = 10mA => Delta_Pressure = (0.01875 * 10  - 0.075) * 100 000 = 11 250 Pascal

Our fluid is watter so the density is 997 kg/m3 => Fluid_Level = 11 250 / (9.81 * 997) = 1.15 m

Default configuration

A default configuration is set:

  • The device reports:
    • the 4-20mA input each day in standard mode and,
    • the voltage of the battery each 7 days.

Every change made to the default configuration must comply with the legal duty cycle (for example, the most restrictive in the EU is 0.1%, which corresponds to approximately 1 frame per hour with SF12)
