SpecificGravity

Store specific gravity in its scientific form (e.g 1.050). Can be constructed either by SpecificGravity(1.050) or SpecificGravity(1050).

The alias SG can be used.

Examples

julia> SpecificGravity(1050)
SG 1050

julia> SpecificGravity(1.050)
SG 1050

julia> SG(1.050)
SG 1050

setprintmode(mode)

Set the printing of SG to either "SG 1000" or "SG 1.000" form. See Examples for details. Default is 0.

Examples

julia> SG(1234)
SG 1.2340

julia> setprintmode(0)
Print mode is set to SG 1.0000

julia> SG(1234)
SG 1.2340

julia> setprintmode(1)
Print mode is set to SG 1000

julia> SG(1234)
SG 1234

plato2sg(plato)

Convert Plato° to specific gravity.

Examples

julia> plato2sg(12)
SG 1048

sg2plato(sg::Number)

Convert specific gravity to Plato°. This method accepts numbers.

Examples

julia> sg2plato(1.050)
12.38764712500003

sg2plato(sg::SG)

A method for converting specific gravity to Plato°, that accepts SpecificGravity.

Examples

julia> sg2plato(SG(1050))
12.38764712500003

gravitycorrection(currentg::SG, targetg::SG, currentvol; boiloffr=nothing)

Calculate the needed correction to achieve targetg gravity.

If boiloffr boil-off rate is given, and wort should be boiled off, the needed boil time is also calculated.

Arguments

• currentg::SG: current specific gravity.
• targetg::SG: target specific gravity.
• currentvol: current volume in L.
• boiloffr=nothing: boil-off rate in L/h (or nothing).

Examples

julia> gravitycorrection(SG(1050), SG(1025), 1)
Dilute with 1.00L water.
1.0000000000000089

julia> gravitycorrection(SG(1050), SG(1075), 1)
Boil off 0.33L water.
-0.33333333333333237

julia> gravitycorrection(SG(1050), SG(1075), 1, boiloffr=2.5)
Boil off 0.33L water. With 2.5L/h: 0.13 hours (8 minutes).
-0.33333333333333237

mixwort(sg1::SG, v1, sg2::SG, v2)

Calculate the resulting wort's gravity when mixing the given the liquids.

Arguments

• sg1::SG: specific gravity of liquid 1.
• v1: volume (in L) of liquid 1.
• sg2::SG: specific gravity of liquid 2.
• v2: volume (in L) of liquid 2.

Examples

julia> mixwort(SG(1050), 1, SG(1000), 1)
(sg = SG 1025, vol = 2)

julia> mixwort(SG(1050), 1, SG(1100), 1)
(sg = SG 1075, vol = 2)

julia> mixwort(SG(1080), 10, SG(1200), 5)
(sg = SG 1120, vol = 15)

gristratio(maltweights)

For an array of weights, print the ratio of every malt. Use the same unit, but only the value is needed.

Examples

julia> gristratio([3500, 500])
3500 --> 87.5%
500 --> 12.5%

julia> gristratio([7700, 1200])
7700 --> 86.5%
1200 --> 13.5%

mdwort(sg::SpecificGravity, vwort, vwater)

mdwort is a shorthand for measure diluted wort. In the calculation only the ratio of the volumes of the liquids matter, so it's sufficient to pass their ratio to the function.

Arguments

• sg::SpecificGravity: specific gravity of the measured wort
• vwort: volume of the wort to be diluted.
• vwater: volume of water used for diluting.

Examples

julia> mdwort(SG(1025), 1, 2)
SG 1.0750

julia> mixwort(SG(1.075), 1, SG(1), 2) # check back
(sg = SG 1.0250, vol = 3)

kettlevol(kd, kh, mh; unit=:cm)

Calculate the volume of wort in the kettle. All arguments must have the same unit. Returns the volume in m^3, and prints it in liters.

Arguments

• kd: (inner) kettle diameter.
• kh: (inner) kettle height.
• mh: (inner) measured "height" of the wort: from the top of the kettle to the top of the wort.
• unit=:cm: can be: mm, :cm, :dm, :m.

Examples

julia> kettlevol(2.5, 3, 2, unit=:dm)
Wort volume: 4.91l
0.0049087385212340535

dme2sugar(dme)

Calculate the "equivalent" of dme gramms of DME in gramms of sucrose.

Examples

julia> 44/46
0.9565217391304348

sgvol2sugar(sg::SG, vol)

How much sugar (sucrose) is needed to get vol liters of liquid with sggravity. Result is in gramms.

Examples

julia> sgvol2sugar(SG(1384), 1) # sucrose pkl is 384, so this should be 1000
999.9999999999997

raisesgbysugar(sgpoints, vol)

How much sugar (sucrose) is needed to raise the gravity of vol volume liquid by sgpoints points. Result is in gramms.

Examples

julia> raisesgbysugar(384, 1)
1000.0

sgofsugarliq(sugar, vol)

Calculate the SG of a liquid mixed from vol liters of water and sugar gramms of sugar (sucrose).

Examples

julia> sgofsugarliq(1000, 1)
SG 1384

julia> sgofsugarliq(1000, 0.5)
SG 1768

processlogfile(fname)

Process a logfile. Return with a NamedTuple with keys: "date", "sg", "temperature", "angle", "battery", "plato". Log entries without an "angle" field will be filtered.

processtuyalogfile(fname)

Process a Tuya-Inkbird logfile. Return with a NamedTuple with keys: "date", "temperature", "set_temperature". Log entries without an "cur_temp" field will be filtered.

masg(dates, sg, stepsize)

Moving average of gravity. A pretty stupid implementation.

promasg(logfiletuple::NamedTuple, window::Hour)

Moving average of gravity. A different implementation, but I think still doesn't comply with moving average's definition. But it's smarter: goes through the data in window-sized steps and calculates the mean of the window before every step.
