Object labels on scheme

In version 22.12.1, it is now possible to hide or configure object labels.

For show/hide labels press F7 or menu View → Show object labels.

For configuring open program settings F12 and edit the appropriate templates. In templates, you can specify some parameters in curly brackets, which will be replaced by the value of the corresponding parameter for a specific object.

Node parameters

• {id} – id
• {name} – name
• {Qself} – consumption of consumers
• {Qtransit} – transit flow through node
• {Q} – full debit through the node (transit + consumption)
• {Qauto} – {Qself} + {Qtransit} for consumers with Qtransit > 0; {Qself} if Qtransit = 0
• {Pin} – input pressure
• {Pout} – output pressure
• {Z} – altitude
• {un_Q} – unit of consumption
• {un_P} – ...pressure
• {un_H} – ...head and altitude

Pipe parameters

• {id}, {name}, {Qself}, {Qtransit}, {un_Q}, {un_P}, {un_H} – same as for nodes
• {Q} – Q = 0.5 * Qself + Qtransit
• {Qauto} – {Qself} + Qtransit} when Qself > 0; {Qtransit} when Qself = 0
• {L} – length
• {D} – diameter
• {n} – roughness
• {k} – coefficient for accounting for local losses
• {Lcalc} – Lcalc = L * k
• {Re} – Reynolds number
• {lambda} – friction factor
• {dP} – pressure loss – full
• {dPL} – ...major (on pipe length)
• {dPR} – ...minor (on local resistances)
• {dPZ} – ...due altitude difference
• {dH} – head loss
• {V} – inner volume
• {Vatm} – gas volume (at Patm)
• {v} – flow velocity
• {v_max} – max. allowable velocity
• {un_L}, {un_D}, {un_n}, {un_V}, {un_v} – same units

Attention! Case (large/small letters) is important!

\n To wrap lines, use the \n combination

Default object signature templates

• Consumers: {id}. {name}\nQ = {Qauto} {un_Q}\nP = {Pin} {un_P}\nZ = {Z} {un_H}
• Splitters: {id}. {name}\nQ = {Q} {un_Q}\nP = {Pout} {un_P}\nZ = {Z} {un_H}
• Reductors and Pipes: {id}. {name}\nQ = {Q} {un_Q}\nP = {Pin} → {Pout} {un_P}\nZ = {Z} {un_H}
• Sources: {id}. {name}\nQ = {Q} {un_Q}\nP = {Pout} {un_P}\nZ = {Z} {un_H}
• Pipes: {name}L = {L} D = {D}\nQ = {Qauto} v = {v}

These are the default templates in version 26.08.2. In other versions, default templates may differ slightly.
