First sign-in

How to sign in, what an office means, and how the rail is organised.

You reach FlowOS in the browser after signing in. This handbook is the one part that opens without a session.

Sign-in doors

Two ways in, both on the same login screen:

• Microsoft — Entra ID for people whose tenant is enrolled.
• Password — an invited account that sets a password from a one-time link.

If the session expires, the app sends you back to login and then to the page you were on.

FlowOS opens on the Global Inbox, and signing in lands there unless you were on your way to another screen. Someone who cannot see the inbox lands on the Dashboard, which stays on the rail for everyone who holds it.

Office

Every person belongs to a home office. Some people also hold grants to other offices. Lists show records from every office you can see, interleaved — there is no “switch office” control. A borrowed office is a grant with a written reason, not a mode. Mumbai, Delhi and Bengaluru rows can appear in the same list; the office mark on the row is how you tell them apart.

See Roles and access.

The rail

The left rail is the product. Entries you do not have permission for are hidden. Some entries are live screens; others name the slice that will carry them and open a placeholder until that slice is on.

Guide at the bottom of the rail opens this handbook. It leaves the product chrome for a docs sidebar.

The top bar above every screen names where you are, such as Master › Item Master. On a screen opened from a list, such as one role under Role Management, the list’s name links back to it. On a phone it shows just the screen’s name.

What is on a live screen today versus still arriving is in Capabilities and the shorter rail list.

Preview as

Administrators who hold preview permission can look at the product as another person, from Preview as in the menu under their avatar, at the right of the top bar. That is a signed-in preview, not a second login. While it is on, the top bar names the person being previewed beside a Stop button, which ends it, as Stop previewing in the same menu does. Nothing they do in a preview is attributed to the other person as if they had signed in.

Theme

The menu under your avatar, at the right of the top bar, picks how FlowOS looks in this browser: Light, Dark, or Match system, which follows the computer’s own setting. Everyone starts on Light. The choice is kept in this browser only, so another computer starts on Light again. Under Dark, an email’s body is shown light on dark, its pictures as they are, and the quotation preview stays on a white page, as it is printed.

On a laptop the same menu sets Density: Comfortable, or Compact for more rows on screen, also kept in this browser. It is left out on a phone.

Unit converter

The Unit converter button in the top bar, on every signed-in page, opens a converter over the page with the keyboard in its one box. Type a figure and its unit together, such as 1700 LPH, 3 kg/cm2g, -3 °C or SG 1.02, or type the figure and pick the unit from the menu at the box’s edge. The converter names the quantity the unit measures, such as Flow · volumetric, and shows the figure in every common unit of it at once:

Figures are shown to five significant figures, grouped in thousands, such as 1,666.7. Choosing a row copies its plain figure, 1666.7, with no thousands separator and no unit, so it pastes into a number box, and says Copied 1666.7 (LPM); the arrow keys move from the box down the rows, Enter on a row copies it, and Escape closes the converter. + another unit… adds any other unit, picked from the list or typed. Where several figures or a range are typed, the first is used, and the converter says so.

A pipe size is a size on the standard ladder, not a length. A size in NB, inch or NPS, such as 50 NB, DN 50 or 2 NPS, is shown as a pipe size: the other of its nominal bore and its size in inches, and its outside diameter as steel pipe (ASME B36.10) and as hygienic tube (ASTM A270), taken from the tables rather than worked out from millimetres. An outside diameter such as 101.6 OD shows its nominal bore and its size in inches only, so it is 100 NB and 4 inch (business rule R106 governs how an OD figure is read). A figure in inches, such as 2 inch or 2", may be either, so it is shown both ways: as a length, 50.8 mm, and under As a pipe size, 50 NB, 60.3 OD steel and 50.8 OD tube. An inch figure that is not on the ladder, such as 2.3 inch, is shown as a length only. Before an inch or pipe-size unit, a fraction of an inch, 1/2", 1-1/2" or 1½", is read as one figure, and so is one after a pipe-size unit, as in NPS 1-1/2. See Nominal bore.

A pressure marked gauge or absolute (barg, psia) is shown in gauge and absolute units, worked between them against a 1.01325 bar atmosphere, which the row notes as assumed. One that says neither, such as 3 bar, is shown in units that say neither.

The unit menu, here and on every Unit box in the line review, lists units by quantity with the ones last picked first, and finds them by plain spellings: deg finds °C, m3 finds m³/h, micro finds µS/cm, kgcm finds kg/cm²(g). On a size box whose unit is NB the menu lists pipe sizes, inch among them.

A row that needs more than the figure says what, in muted text, such as “needs operating pressure and temperature”, with an Add conditions link. Pressing it opens Conditions beneath the rows with only the inputs the rows ask for. A unit that needs conditions to reach the plain rows, such as 100 kg/h to m³/h, opens them by itself, and a recent conversion that carried conditions opens them too. Once open they stay open for that conversion.

• Liquid, Gas or Steam, which choosing a library fluid sets as the library classes the fluid, whatever its name: its Steam is steam, Steam Reforming Gas a gas and Gas condensate a liquid.
• The Fluid, from the fluid library.
• Pressure, Temperature and Density, each typed or picked in any unit and shown as read: 43.5 psig reads = 3 bar(g), 104 F reads = 40 °C, SG 1.02 reads = 1,020 kg/m³. A pressure must say gauge or absolute.

A gas between actual and normal volume, such as m³/h to Nm³/h, needs the operating pressure and temperature. It is worked out as an ideal gas against a 1.01325 bar atmosphere, whatever the gas. The row shows the pressure and temperature it used, such as at 3 bar(g), 40 °C, and hovering it (or reading its description) gives the whole sentence, with the atmosphere; a temperature left blank is taken as 20 °C, marked assumed. A mass flow and a volume, such as kg/h and m³/h, need the fluid or its density; for a gas the library gives its normal density, and its actual volume also needs the pressure and temperature. Steam needs its pressure or temperature, from which its density is read off the steam tables.

Recent, at the foot, keeps the last five conversions in this browser: each one entered with Enter, copied from, or open when the converter closed. A chip loads it back with its conditions, and Clear forgets them all.
