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)
