Functions

func CurrentToRatio

func CurrentToRatio(current float64) float64

Returns the 4-20mA input signal to a ratio, 4000uA => 0.0, 8000uA => 0.25, 12000uA => 0.5, 16000uA => 0.75, 20000uA => 1.0 current is in uA (1000000uA is 1A) return value is a ratio (0.0 .. 1.0)

func HeightToVolume

func HeightToVolume(height float64, sensorOffset float64, heights []interface{}, volumes []interface{}) (result float64, err error)

Returns the HeightToVolume corresponding to the measured height. This function is used when a pressure sensor is used in a tank. height is in m sensorOffset is in m (positive means that the sensor is placed above the bottom of the tank, negative value means that the sensor is place below the tank) heights is in m, list of heights with corresponding volumes volumes is in m3, list of volumes with corresponding heights return value is in m3

func ListToFloats

func ListToFloats(input []interface{}) ([]float64, error)

func PressureToHeight

func PressureToHeight(pressure float64, density float64) float64

Converts a pressure and density to a height pressure is in Pa (1 Bar is 100000 Pascal) density is in kg/m3 (typical value for diesel is 840) return value is in m

func RegistersToCoils

func RegistersToCoils(registers []uint16, numberOfCoils uint16) []bool
