Description#

The sample tank simulates the sampling of a material flow. Specifically, this block fills, holds material for a specified amount of time, then empties. The user can optionally specify additional material that should be added when the inflow is non-zero (i.e., material is arriving at this block).

When the tank inventory for Process level basis falls below the Tank off point, flow out is prohibited and the surge signal turns on.

Mask dialog options#

Tank level basis : string

The element or isotope used for the tank level min and max.

Tank off point (kg) : float

The switch off level for the tank. If the tank inventory of the element or isotope specified in Tank level basis falls below this value, then flow out from the block is prohibited and the surge signal is activated.

Tank on point (kg) : float

The switch on level of the tank. If the tank inventory of the element or isotope specified in Tank level basis rises above this value, then flow out from the block is permitted after a hold period Sample time (hr) has elapsed.

Match inflow : boolean

If selected, then the output flow from this block will match the input flow.

Flowrate (kg/hr): float

The flowrate out for the tank in kg/hr.

Additions : string, float

An optional table of strings specifying a species (either elemental or isotopic) and a flow rate. If this table is used, materials are only added when a non-zero signal is present in In(c).

Sample time (hr) : float

The amount of time to hold material after the Tank on point has been reached.

Ports#

In(C) : signal

Signal representing inflow to the tank. Has shape [1677, 1]. Width is dependent on mask dialog input and height is derived to ensure integration of the signal equals the original input entity.

Feed(C) : signal

Optional feed signal. Should have shape [1677, 1].

Outputs#

Out(C) : signal

Continuous signal representing tank output. Has the same shape as In(C).

Srg(C): signal

Surge signal. Should be either 0 or 1 to represent flow disabled or enabled, respectively.

Add(C): signal

Signal that represents material that is being added by the additions dialog table. Can be used for consistency checks.

Inv : signal

Continuous inventory signal with shape [1677, 1]. Updated when entities enter and the residual signal leaves.
